LAMP 三层独立架构部署

倒流’s Bolg

考虑到复杂的应用环境,我们将apache/php/mysql三种服务独立配置不同主机

我们知道apache与php有三种工作模式:
[list]
[*]CGI
[*]Modules
[*]FastCGI
[/list]
第一种现在用得很少了,性能差;对于动态页面全部由apache进程启用php解释器,然后再释放
第二种需要到本地磁盘加载Modules模块,性能比第一种好,但还是会有很多消耗资源
第三种php是一个独立应用,通过网络套接字接口,接收apache进程传过来的请求,所有php进程都由php自身管理
在php5.4以前,如果php需要连接mysql需要mysql头文件等,
在php5.4以后就不需要了,直接使用 “–with-mysql=mysqlnd –with-pdo-mysql=mysqlnd –with-mysqli=mysqlnd”
由于apache并不处理动态页面,所以前端用户请求的php页面需要转发到php服务器上,这里就需要对apache做反向代理设置
当然了,我们在这里最好启用虚拟主机功能,这样方便管理。

[root@station02 php-5.4.13]# chkconfig php-fpm on
[root@station02 php-5.4.13]# cd /usr/local/php/
[root@station02 php]# cp etc/php-fpm.conf.default etc/php-fpm.conf
[root@station02 php]# vim etc/php-fpm.conf

配置fpm的相关选项为你所需要的值,并启用pid文件:

pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8
pid = /usr/local/php/var/run/php-fpm.pid
[root@station02 php]# service php-fpm start

检查php-fpm是否正常

[root@station02 php]# netstat -tunlp |grep 9000
[root@station02 php]# ps -ef |grep php-fpm
