CentOS 上部署Discuz!X论坛1
前言
应公司需求,最近需要搭建一个内部员工交流的论坛,任务自然落到我的头上。所以这篇博文也就是记录一下部署过程,也希望各位博友多多指点。
Discuz! X 是一款以 PHP 为编程语言,以 MySQL 为数据库,并使用 Apache/IIS/Nginx(任意一种即可) 提供 web 服务的产品。要搭建 Discuz! X 站点,服务器必须安装由 PHP、MySQL、Apache/IIS/Nginx 构成的环境。其中,IIS 主要用于 Windows 服务器,Apache、Nginx 多用于 Linux 服务器(即 LAMP 和 LNMP)。
我这里采用的是LAMP架构,具体的部署环境如下:
CentOS 6.5 x64
Apache 2.4.10
MySQL 5.5.39
PHP 5.4
Discuz_X3.2_SC_UTF8
部署过程
CentOS系统的安装过程
这里就不讲解了,否则篇幅过于冗长。如果有需要的同学,请参考《使用VMware Workstation安装CentOS 5.8》。或者google之。
系统安装完成之后,做一些基本的优化操作
更新yum源为国内网易163的源
同步时间
打开文件数量限制
SELinux 和 iptables
内核参数调优
关闭不需要的服务
ssh服务配置
注意:如果是root用户通过ssh软件远程连接到Linux服务器可要小心了,因为此脚本会配置sshd禁止root用户远程登录。

LAMP环境搭建
在安装之前,我们先关闭掉iptables,最后再开启它。
因为后期要编译源码包,所以我们需要安装所需的开发工具包。
编译安装的原则:对于我来说,需要定制的就直接编译,其余的一切皆yum / apt-get搞定
下载的软件包列表如下:在开始安装之前,最好先用rpm -qa 检查一下是否已经安装了相应的包,因为我这里是最小化安装,所以就跳过这个步骤了。
[root@localhost lamp]# ls -l total 196880 -rw-r--r--. 1 root root 1020833 Sep 13 16:29 apr-1.5.1.tar.gz -rw-r--r--. 1 root root 874462 Mar 18 17:16 apr-util-1.5.3.tar.gz -rw-r--r--. 1 root root 6820719 Sep 13 16:27 httpd-2.4.10.tar.gz -rw-r--r--. 1 root root 172464 Mar 20 13:54 libmcrypt-2.5.7-1.2.el6.rf.i686.rpm -rw-r--r--. 1 root root 84680 Mar 20 13:54 libmcrypt-devel-2.5.7-1.2.el6.rf.i686.rpm -rw-r--r--. 1 root root 100230 Mar 26 13:49 mod_fastcgi-2.4.6.tar.gz -rw-r--r--. 1 root root 177020618 Jul 20 11:00 mysql-5.5.38-linux2.6-i686.tar.gz -rw-r--r--. 1 root root 15323862 Sep 13 16:27 php-5.4.32.tar.gz -rw-r--r--. 1 root root 166263 Sep 13 16:28 xcache-3.0.4.tar.gz
1、编译安装httpd
我这里仅列出简明扼要的命令,详细的安装步骤可以参考《编译安装LAMP之一》。
