Nginx+Apache有效提高服务器负载能力-LNAMP

之前流行过一段时间的Nginx+以fastCGI方式运行的PHP来搭建Web站点的方法。但是经过一段时间考量之后,大家经常发现会出现一些502的错误。其实一般是Nginx+fastCGIPHP的形式不太稳定造成。于是尝试了牛人推荐的一种是用Nginx做前端转发PHP请求给Apache的方法来进行服务器平台建设。这种方法有效的避免了Apache在应付大并发时候的些许不足和Nginx配合fastCGIPHP不太稳定的弊端。同时又在一定程度上利用了Nginx速度上的优势。说白了就是一些静态文件有Nginx来处理,PHP请求转发给后端Apache来处理。但是在效率上或者内存等资源占用上不如Nginx+fastCGI方式。

在PHP页面处理使用了suPHP,关于suPHP各位可以参照这里。suPHP其实现在被应用在很多空间租用商的服务器上。主要功能为了使用目录所有者的权限来执行特定位置的PHP页面,不是使用Apache默认Apache或者wwwdata或者nobody用户。

这样的好处主要有两点:
1.空间租用者(使用者)不需要在设置复杂权限了,在自己空间中PHP拥有完全权限。
2.空间租用者(使用者)存放网站文件的目录更安全,不需要开启Apache,wwwdate或者nobody之类权限对于自己站点,避免了777这样的高危权限。但是suPHP要求在编译安装PHP的时候必须编译为PHP-CGI形式才能是用,也就是不能使用平时我们所使用的CLI启动方式。

简单原理如下: CLI传统模式的图解:PHP是作为Apache一个模块存在,就像Apache的一个功能一样。

Apache_Mod-PHP-CLI

suPHP模式图解:suPHP作为Apache一个模块,在需要的时候以特定用户权限来启动PHP-CGI,从而实现以目录所有者权限执行PHP的功能。

Apache_Mod-suPHP_PHP-CGI

最终原理图大致如下:由Nginx接受全部目的端口为80的Web请求,根据请求内容的不同进行过滤。静态文件例如:MP3、GIF、JPG、JS等文件 由Nginx处理,其他PHP Web请求转发到后端Apache服务器上。Apache服务器利用suPHP模块按照目录所有者权限运行PHP程序从而返回页面给客户端。稍加改动就可 以实现跨越多台计算机的群集功能。

我们操作系统平台为CentOS5.5,姑且称呼他为:Nginx+Apache+MySQL+suPHP
Nginx-Apache-MySQL-suPHP

编辑Pure-FTP配置文件

#配置pure-ftpd,这里采用PureDB的验证方式.
vim /usr/local/pureftpd/etc/pure-ftpd.conf
#查找 PureDB /etc/pureftpd.pdb 取消前面的#号并设置成
PureDB /usr/local/pureftpd/etc/pureftpd.pdb
#查找 PassivePortRange 取消前面的#号
# PS:如果想用系统用户验证
设置成以下值。
UnixAuthentication            yes
#MinUID                      100
UnixAuthentication yes表示系统用户可以登录FTP。
MinUID 100表示用户的ID大于100才能登录,我们注释掉它,任何的用户ID都能登录了。

三、设置各服务开机自运行并启动服务

chkconfig --level 35 mysql on
chkconfig --level 35 httpd on
chkconfig --level 35 nginx on

启动和停止PureFTPd
service pure-ftpd stop
service pure-ftpd start
service pure-ftpd status

#以下内容为一行,请注意
echo '/usr/local/bin/memcached -d -m 64 -p 11211 -u nobody -l localhost' >>/etc/rc.d/rc.local
service mysql start
service httpd start
service nginx start
/usr/local/bin/memcached -d -m 64 -p 11211 -u nobody -l localhost

四、如何使用和创建虚拟主机 更改用户模板文件

mkdir /etc/skel/public_html

添加FTP帐户用于维护Web服务器

useradd -s /sbin/nologin whypc_info
chmod a+x ~whypc_info
pure-pw useradd whypc_info -u whypc_info -g \
whypc_info -d /home/whypc_info/  #该命令之后会提示你设置FTP用户密码
pure-pw mkdb   #该命令每次添加用户之后都需要执行,不需要重启服务。

#启动Pure-FTP因为刚才还没有产生用户数据库,所以在这里启动。
/usr/local/pureftpd/sbin/pure-config.pl\
/usr/local/pureftpd/etc/pure-ftpd.conf --daemonize

更改Apache配置文件增加虚拟主机

cd /usr/local/apache/conf/vhosts
vim whypc.info.conf
#添加如下内容,IP地址和域名根据实际情况。
<VirtualHost 204.74.291.132:81>
  ServerName whypc.info
  ServerAlias www.whypc.info
  DocumentRoot /home/whypc_info/public_html
  UseCanonicalName Off
  CustomLog /usr/local/apache/domlogs/whypc.info combined
  Options -ExecCGI -Includes
  RemoveHandler cgi-script .cgi .pl .plx .ppl .perl
  suPHP_Engine on
  suPHP_UserGroup whypc_info whypc_info
  AddHandler x-httpd-php .php .php3 .php4 .php5
  suPHP_AddHandler x-httpd-php
  <IfModule !mod_disable_suexec.c>
    SuexecUserGroup whypc_info whypc_info
  </IfModule>
  ScriptAlias /cgi-bin/ /home/whypc_info/public_html/cgi-bin/
</VirtualHost>

更改Nginx配置文件增加虚拟主机

cd /usr/local/nginx/conf/vhosts/
vim whypc.info.conf
#添加如下内容,IP地址和域名根据实际情况。
server {
access_log off;
error_log /usr/local/nginx/logs/whypc.info-error_log warn;
listen 80;
server_name whypc.info www.whypc.info;
access_log off;
location ~* ^.+.(gif|jpg|jpeg|png|ico|wmv|avi|asf|asx|mpg|mpeg\
|mp4|pls|mp3|mid|wav|swf|flv|html|htm|txt|js|css|exe|zip|rar\
|gz|tgz|bz2|uha|7z|doc|docx|xls|xlsx|pdf|iso)$ {
access_log /usr/local/apache/domlogs/whypc.info combined;
root /home/whypc_info/public_html/;
expires 24h;
try_files $uri @backend;
}
error_page 400 401 402 403 404 405 406 407 408 409 500 501 502 503 504 @backend;
location @backend {
internal;
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_send_timeout   300;
proxy_read_timeout   300;
proxy_buffer_size    4k;
proxy_buffers     16 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_connect_timeout 30s;
proxy_redirect http://whypc.info:81 http://whypc.info;
proxy_redirect http://www.whypc.info:81 http://www.whypc.info;
proxy_pass http://204.74.291.132:81;
proxy_set_header   Host   $host;
proxy_set_header   X-Real-IP  $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ~* \.(ftpquota|htaccess|asp|aspx|jsp|asa|mdb)$ {
deny  all;
}
location / {
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_send_timeout   300;
proxy_read_timeout   300;
proxy_buffer_size    4k;
proxy_buffers     16 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_connect_timeout 30s;
proxy_redirect http://whypc.info:81 http://whypc.info;
proxy_redirect http://www.whypc.info:81 http://www.whypc.info;
proxy_pass http://204.74.291.132:81;
proxy_set_header   Host   $host;
proxy_set_header   X-Real-IP  $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

五、创建测试文件

vim ~whypc_info/public_html/test.php
#写入如下内容
<?php
         system("id");
?>
chown whypc_info:whypc_info ~whypc_info/public_html/test.php
通过浏览器查看是否为目录所有者权限(非nobody)。

    新版PHP,已经不会出现502错误了,建议用新版PHP-FPM

    1. JavasBoy 2013年6月24日 16:10

      是的,已经在使用单Nginx配合PHP-FPM。^_^
