SMTP：简单邮件传输协议

（SMTP：Simple Mail Transfer Protocol）

SMTP 是一种提供可靠且有效电子邮件传输的协议。 SMTP 是建模在 FTP 文件传输服务上的一种邮件服务，主要用于传输系统之间的邮件信息并提供来信有关的通知。

SMTP 独立于特定的传输子系统，且只需要可靠有序的数据流信道支持。 SMTP 重要特性之一是其能跨越网络传输邮件，即“ SMTP 邮件中继”。通常，一个网络可以由公用互联网上 TCP 可相互访问的主机、防火墙分隔的 TCP/IP 网络上 TCP 可相互访问的主机，及其它 LAN/WAN 中的主机利用非 TCP 传输层协议组成。使用 SMTP ，可实现相同网络上处理机之间的邮件传输，也可通过中继器或网关实现某处理机与其它网络之间的邮件传输。

在这种方式下，邮件的发送可能经过从发送端到接收端路径上的大量中间中继器或网关主机。域名服务系统（DNS）的邮件交换服务器可以用来识别出传输邮件的下一跳 IP 地址。

SMTP端口号是多少?

25

什么是SMTP服务器?

SMTP是SIMPLE MAIL TRANSFER PROTOCOL的缩写，一般的发信软件，如Outlook Express、FoxMail、Eudora都是使用这个协议进行发信的。如果你的ISP没有提供SMTP服务器，那你就无法使用该协议发送信件。无法从一个邮箱的域名知道它是否提供SMTP服务或者SMTP服务器是什么。如果不知道自己信箱的SMTP服务器，可以向提供信箱的ISP询问。现在为了避免滥发垃圾邮件，许多免费邮件的提供商都不提供SMTP服务器，如Hotmail、eyou，这些免费邮件用户只能登录后通过浏览器发信。收费邮件一般都提供POP3和SMTP服务器

此服务器要求支持Zend Framework(同样支持大多数PHP DEV的需求).

 进入mysql
 /usr/local/mysql/bin/mysql -u root -p
 停止、启动mysql
 /usr/local/mysql/support-files/mysql.server { stat | stop }
 service mysqld { stat | stop }

MySQL路径为/usr/local/mysql

去PHP官网下载最新的源码包，我下的是php-5.2.6.tar.bz2。

pspell-.12.2.tar.gz

mkdir /usr/local/pspell
cd pspell-.12.2
./configure --prefix=/usr/local/pspell
make; make install

a.安装 jpeg6
建立目录：

mkdir -p /usr/local/jpeg
mkdir -p /usr/local/jpeg/bin
mkdir -p /usr/local/jpeg/lib
mkdir -p /usr/local/jpeg/include
mkdir -p /usr/local/jpeg/man
mkdir -p /usr/local/jpeg/man1
mkdir -p /usr/local/jpeg/man/man1
cd /home/source/software/
tar -zvxf jpegsrc.v6b.tar.gz
cd jpeg-6b
./configure --prefix=/usr/local/jpeg/ --enable-shared --enable-static
make; make install

备注：

在64 位下编译jpeg-6b时候报以下错误： 

make: ./libtool: Command not found 
make: *** [jcapimin.lo] Error 127 

错误分析：由于libtool版本过低导致的，重新下载新版本的libtool以默认方式安装，执行以下命令： 

./configure 
make 
make install 

然后进入jpeg-6b的源码目录，然后执行以下步骤，切记！ 

cp /usr/share/libtool/config.sub . 
cp /usr/share/libtool/config.guess . 
./configure --prefix=/usr/local/jpeg/ --enable-shared --enable-static 
make 
make install 

b.:安装zlib

cd /home/source/software/
tar -zxvf zlib-1.2.3.tar.gz
mkdir -p /usr/local/zlib
cd zlib.1.2.3
./configure --prefix=/usr/local/zlib
make;make install

c.安装 freetype

cd /home/source/software/
tar -zvxf freetype-2.1.10.tar.gz
cd freetype-2.1.10
mkdir -p /usr/local/freetype
./configure --prefix=/usr/local/freetype
make;make install

d.安装libpng

cd /home/source/software/
mkdir -p /usr/local/png
tar -zvxf libpng-1.2.8.tar.gz
cd libpng-1.2.8
cp scripts/makefile.std makefile
 
vi makefile

不要用prefix定义路径否则会影响gd安装

ZLIBLIB=/usr/local/zlib
ZLIBINC=/usr/local/zlib/include

make; make install

e.安装gettext
ftp://ftp.gnu.org/gnu/gettext/gettext-0.17.tar.gz

tar xf gettext-0.17.tar.gz
cd gettext-0.17
mkdir /usr/local/gettext
./configure --prefix=/usr/local/gettext
make
make install

f.安装GD库

cd /home/source/software/
tar -zvxf gd-2.0.33.tar.gz
mkdir -p /usr/local/gd2
cd gd-2.0.33
./configure --prefix=/usr/local/gd2 --with-jpeg=/usr/local/jpeg/
--with-zlib=/usr/local/zlib
--with-freetype=/usr/local/freetype/
--with-png
make; make install

安装GD
tar xzvf gd-2.0.35.tar.gz
cd gd-2.0.35
./configure –prefix=/usr/local/gd2 –with-jpeg=/usr/local/jpeg6/ –with-png –with-zlib –with-freetype=/usr/local/freetype/ –with-fontconfig=/usr/local/fontconfig
make
make install
错误：
configure.ac:64: error: possibly undefined macro: AM_ICONV
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
解决：
cd ..
tar zxvf gettext-0.17.tar.gz
cd gettext-0.17
./configure –prefix=/usr/local/gettext –disable-java –disable-native-java
make
make install
/bin/sed: can’t read /lib/libattr.la: No such file or directory
ln -s /usr/lib/* /lib/
再安装gettext
再安装gd

X86 64位LINUX下安装GD的注意事项
错误提示：
/usr/bin/ld: /usr/local/lib/libjpeg.a(jcapimin.o): relocation R_X86_64_32 against `a local symbol’ can not be used when making a shared object; recompile with -fPIC

进入Jpeg目录
CFLAGS=”-O3 -fPIC” ./configure
make
make install-lib

编译前需指定为64位编译模式，否则会出现以下错误：
/usr/bin/ld: /usr/local/lib/libz.a(crc32.o): relocation R_X86_64_32against `a local symbol’ can not be used when making a shared object;recompile with -fPIC
/usr/local/lib/libz.a: could not read symbols: Bad value
解决办法 : 重新安装 zlib-1.2.3.tar.gz

tar -zxvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure

vi Makefile
找到 CFLAGS=-O3 -DUSE_MMAP
在后面加入-fPIC，即变成CFLAGS=-O3 -DUSE_MMAP -fPIC
接下面步骤

make
make install

nfig.so -L/usr/lib64 /usr/local/freetype/lib/libfreetype.so -lpng -lz -lm -Wl,–rpath -Wl,/usr/local/freetype/lib -Wl,-soname -Wl,libgd.so.2 -o .libs/libgd.so.2.0.0
/usr/bin/ld: /usr/local/lib/libpng.a(png.o): relocation R_X86_64_32 against `a local symbol’ can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libpng.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
重新安装libpng;删除解压文件，重新解压
cp scripts/makefile.linux makefile
vi Makefile
找到 CFLAGS=后加上-fPIC
make test
make install

再重新安接gd;
vi Makefile
找到 CFLAGS=后加上-fPIC

g.安装Curl库

cd /home/source/software/
tar -zvxf curl-7.15.0.tar.gz
mkdir -p /usr/local/curl
./configure --prefix=/usr/local/curl
make; make install

h.安装libxml2

cd /home/xiutuo/software/
tar -zxvf libxml2-2.6.24.tar.gz
cd libxml2-2.6.24
mkdir -p /usr/local/libxml2
./configure --prefix=/usr/local/libxml2
make; make install

i.安装libiconv-1.12.tar.gz

tar -zxvf libiconv-1.12.tar.gz
cd libiconv-1.12
./configure --prefix=/usr/local/libiconv
make
make install
make clean

j.安装libmcrypt
ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.7.tar.gz

tar xf libmcrypt-2.5.7.tar.gz
mkdir /usr/local/libmcrypt
cd libmcrypt-2.5.7
./configure --prefix=/usr/local/libmcrypt
make
make install

k.安装mhash

http://voxel.dl.sourceforge.net/sourceforge/mhash/mhash-0.9.9.tar.gz

tar xf mhash-0.9.9.tar.gz
cd mhash-0.9.9
mkdir /usr/local/mhash
./configure --prefix=/usr/local/mhash/
make;make install

j.安装PHP

如果使用PHP-FPM (PHP FastCGI Process Manager)来对进程进行管理，则需要提前做如下工作：
请阅读:《使用PHP-FPM (PHP FastCGI Process Manager)来对php-cgi进程进行管理》

$ sudo -s
$ mkdir /usr/local/php
$ mkdir /usr/local/php/sourcecode
$ mv ~/Download/php-5.2.6.tar.bz2 /usr/local/php/sourcecode
$ cd /usr/local/php/sourcecode
$ tar xf php-5.2.6.tar.bz2
$ cd php-5.2.6

$ ./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-fastcgi --enable-force-cgi-redirect --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-curl=/usr/local/curl --with-libxml-dir=/usr/local/libxml2 --with-libexpat-dir=/usr/lib --with-gd=/usr/local/gd2/ --with-jpeg-dir=/usr/local/jpeg/ --with-zlib-dir=/usr/local/zlib/ --with-png-dir=/usr/local/png/ --with-freetype-dir=/usr/local/freetype/ --enable-soap --enable-sockets --enable-dom --enable-sysvshm=yes --enable-ftp --enable-calendar --enable-sockets --with-db4 --with-bz2 --with-iconv=/usr/local/libiconv --with-gettext=/usr/local/gettext --with-mcrypt=/usr/local/libmcrypt --enable-mbstring=cn --with-mhash=/usr/local/mhash --with-mime-magic --with-openssl --disable-cli --enable-bcmath --enable-calendar --enable-ctype --enable-shmop --enable-soap --enable-sockets --enable-wddx --enable-zip --enable-dba=shared --enable-dbase --enable-exif --with-pspell=/usr/local/pspell --with-gmp
$ make
$ make install

当编译php时如果在64位系统下出现如下报错信息

checking for MySQL UNIX socket location… no
checking for mysql_close in -lmysqlclient… no
checking for mysql_error in -lmysqlclient… no
configure: error: mysql configure failed. Please check config.log for more information.
是使用了二进制的mysql所致，请下载mysql源码进行64位的编译安装。

说明：
sudo -s切换到超级用户模式，输入你的密码；
mkdir /usr/local/php建立php 5.2.6的安装目录；
mkdir /usr/local/php/sourcecode 并建立源码包存放位置，以方便日后快速的往php里面添加所须的模块；
解压缩，然后配置安装。

Mac OS 10.5不带PCRE，而PCRE又是NGINX不可缺少的，所以要我们自己安装。

$ mkdir -p /usr/local/src
$ cd /usr/local/src
$ curl -O ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz
$ tar xvfz pcre-7.7.tar.gz
$ cd pcre-7.7
$ ./configure --prefix=/usr/local --enable-utf8
$ make
$ make install
$ cd ..

可以直接到官方下载源码包，也可以从用下面的CURL下载。

$ cd /tmp
$ curl -O http://sysoev.ru/nginx/nginx-0.6.32.tar.gz
$ tar xvfz nginx-0.6.32.tar.gz
$ cd nginx-0.6.32
$ ./configure --prefix=/usr/local/nginx --with-http_ssl_module
$ make
$ sudo make install

启动NGINX：

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

至此东西安装好了，看下http://localhost/，是不是nginx在欢迎你进入它的世界呢？呵呵，如果你看到了，那么恭喜你。

NGINX配置文件修改:

server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location ~ .*\.php?$ {
fastcgi_pass 127.0.0.1:1026;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

启动PHPCGI：

/usr/local/php/bin/php-cgi -q -b "127.0.0.1:1026"

此时你可以在/usr/local/nginx/html/底下写一个index.php，然后访问http://localhost/index.php
phpinfo();
?>

bash-3.2# curl -o http://www.lighttpd.net/download/lighttpd-1.4.20.tar.gz
bash-3.2# tar xf lighttpd-1.4.20.tar.gz
bash-3.2# cd lighttpd-1.4.20
bash-3.2# ./configure
bash-3.2# make
bash-3.2# cp src/spawn-fcgi /usr/local/nginx/sbin/

bash-3.2# /usr/local/nginx/sbin/spawn-fcgi -p 1026 -C 5 -u nobody -g nobody -f /usr/local/php/bin/php-cgi

也可以自己写个shell脚本，在此就不多写了。

大公告成～！

备注：

若出现这个错误

error while loading shared libraries: /usr/local/gd/lib/libgd.so.2: cannot restore segment prot after reloc: Permission denied

原来这是SELinux搞的鬼，解决办法有如下两个
1. 使用chcon 命令
示例: chcon -t texrel_shlib_t /usr/local/gd/lib/libgd/*.so.2
2. 禁止掉SELinux
更改/etc/sysconfig/selinux 文件的内容为 SELINUX=disabled

附加使用教程：
关闭NGINX:(Mac OS 用户可以通过活动监视器杀死nginx进程)

killall -9 nginx

不中断服务，重新启动NGINX:

ps -aux | grep nginx

查看主进程号pid

kill -HUP pid

作者：JoshuaLJD

wget命令可以在linux下进行下载文件，这里的用法是摘自其GNU的帮助文档，由于都是E文，所以亲自用了一下，并记录其要点，以便日后翻阅:

Simple Usage 简单用法：
1、Say you want to download a URL. Just type:
wget http://fly.srk.fer.hr/ 最简单直接下载

2、But what will happen if the connection is slow, and the file is lengthy? The connection will probably fail before the whole file is retrieved, more than once. In this case, Wget will try getting the file until it either gets the whole of it, or exceeds the default number of retries (this being 20). It is easy to change the number of tries to 45, to insure that the whole file will arrive safely:
wget –tries=45 http://fly.srk.fer.hr/jpg/flyweb.jpg 注:–tries=45是当服务器无反应时，连续重试连接45次，当为0是则无限次重下载.

Now let’s leave Wget to work in the background, and write its progress to log file log. It is tiring to type –tries, so we shall use -t.
wget -t 45 -o log http://fly.srk.fer.hr/jpg/flyweb.jpg 注：-o log 把显示的信息写信到log文件中，亦可改为:wget -t 45 -o log.txt http://www.wcsky.com 即信息写入到log.txt文件中。

The ampersand at the end of the line makes sure that Wget works in the background. To unlimit the number of retries, use -t inf.

The usage of FTP is as simple. Wget will take care of login and password.
wget ftp://gnjilux.srk.fer.hr/welcome.msg

Advanced Usage 高级用法
1、Create a five levels deep mirror image of the GNU web site, with the same directory structure the original has, with only one try per document, saving the log of the activities to gnulog:
wget -r http://www.gnu.org/ -o log 注：-r 下载http://www.gnu.org/文件的镜像内容。

The same as the above, but convert the links in the HTML files to point to local files, so you can view the documents off-line:
wget –convert-links -r http://www.gnu.org/ -o gnulog 注：下载http://www.gnu.org/文件的镜像内容以及内容中的链接为本地的链接。

2、Retrieve only one HTML page, but make sure that all the elements needed for the page to be displayed, such as inline images and external style sheets, are also downloaded. Also make sure the downloaded page references the downloaded links.
wget -p –convert-links http://www.server.com/dir/page.html

The HTML page will be saved to www.server.com/dir/page.html, and the images, stylesheets, etc., somewhere under www.server.com/, depending on where they were on the remote server.

3、The same as the above, but without the www.server.com/ directory. In fact, I don’t want to have all those random server directories anyway–just save all those files under a download/ subdirectory of the current directory.
wget -p –convert-links -nH -nd -Pdownload http://www.server.com/dir/page.html

wget -Pdownload http://www.wcsky.com 注：下载http://www.wcsky.com里的面容到download文件夹中，如果此文件夹不存在，它会自动创建。

4、Retrieve the index.html of www.lycos.com, showing the original server headers:
wget -S http://www.lycos.com/ 注：-S : 用来显示服务器端的头信息，

5、Save the server headers with the file, perhaps for post-processing.
wget -s http://www.lycos.com/ 注：-s:下载其URL文件，并把头信息写入到文件中。

6、Retrieve the first two levels of wuarchive.wustl.edu, saving them to /tmp.
wget -r -l2 -P/tmp ftp://wuarchive.wustl.edu/

7、You want to download all the GIFs from a directory on an HTTP server. You tried wget http://www.server.com/dir/*.gif, but that didn’t work because HTTP retrieval does not support globbing. In that case, use:
wget -r -l1 –no-parent -A.gif http://www.server.com/dir/

More verbose, but the effect is the same. -r -l1 means to retrieve recursively (see Recursive Retrieval), with maximum depth of 1. –no-parent means that references to the parent directory are ignored (see Directory-Based Limits), and -A.gif means to download only the GIF files. -A “*.gif” would have worked too.

8、Suppose you were in the middle of downloading, when Wget was interrupted. Now you do not want to clobber the files already present. It would be:
wget -nc -r http://www.gnu.org/

wget -c http://www.wcsky.com/1.mp3 注：-c:用于断点续传。超实用！！

9、If you want to encode your own username and password to HTTP or FTP, use the appropriate URL syntax (see URL Format).
wget ftp://hniksic:mypassword@unix.server.com/.emacs

Note, however, that this usage is not advisable on multi-user systems because it reveals your password to anyone who looks at the output of ps.

10、You would like the output documents to go to standard output instead of to files?
wget -O – http://jagor.srce.hr/ http://www.srce.hr/

You can also combine the two options and make pipelines to retrieve the documents from remote hotlists:wget -O – http://cool.list.com/ | wget –force-html -i -

首先Apache的Rewite规则差别不是很大,但是Nginx的Rewrite规则比Apache的简单灵活多了
Nginx可以用if进行条件匹配，语法规则类似C

if ($http_user_agent ~ MSIE) {
rewrite ^(.*)$ /msie/$1 break;
}
官方文档请点击这里
Rewrite的Flags

Flags can be any of the following:
* last - completes processing of rewrite directives, after which searches for corresponding URI and location
* break - completes processing of rewrite directives
*redirect - returns temporary redirect with code 302; it is used if the substituting line begins with http://
* permanent - returns permanent redirect with code 301

last – 完成重写指令后，搜索相应的URI和位置。相当于Apache里的[L]标记，表示完成rewrite，不再匹配后面的规则。
break – 中止Rewirte，不在继续匹配。
redirect – 返回临时重定向的HTTP状态302。
permanent – 返回永久重定向的HTTP状态301。

ZEND Framework的重定向规则：
案例一：
全部重定向到 /index.php
rewrite ^/(.*) /index.php?$1&;
案例二：
如果文件或目录不存在则重定向到index.php
if (!-e $request_filename) {
rewrite ^/(.*) /index.php?$1&;
}

WordPress的重定向规则：
案例一：
http://www.wemvc.com/12 重定向到 http://www.wemvc.com/index.php?p=12
if (!-e $request_filename) {
rewrite ^/(.+)$ /index.php?p=$1 last;
}
案例二：
与zendframework配置很像
if (!-e $request_filename) {
rewrite ^/(.*) /index.php?$1&;
}

以下为Discuz完整的Rewrite for Nginx规则
if (!-f $request_filename) {
rewrite ^/archiver/((fid|tid)-[\w\-]+\.html)$ /archiver/index.php?$1 last;
rewrite ^/forum-([0-9]+)-([0-9]+)\.html$ /forumdisplay.php?fid=$1&page=$2 last;
rewrite ^/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /viewthread.php?tid=$1&extra=page%3D$3&page=$2 last;
rewrite ^/space-(username|uid)-(.+)\.html$ /space.php?$1=$2 last;rewrite ^/tag-(.+)\.html$ /tag.php?name=$1 last;
}

文件及目录匹配，其中：
-f和!-f用来判断是否存在文件
-d和!-d用来判断是否存在目录
-e和!-e用来判断是否存在文件或目录
-x和!-x用来判断文件是否可执行

正则表达式全部符号解释
~ 为区分大小写匹配
~* 为不区分大小写匹配
!~和!~* 分别为区分大小写不匹配及不区分大小写不匹配
(pattern) 匹配 pattern 并获取这一匹配。所获取的匹配可以从产生的 Matches 集合得到，在VBScript 中使用 SubMatches 集合，在JScript 中则使用 $0…$9 属性。要匹配圆括号字符，请使用 ‘\(‘ 或 ‘\)’。
^ 匹配输入字符串的开始位置。
$ 匹配输入字符串的结束位置。
