简明过程
1. 参考
但是，实际上可以不用这么复杂。而且由于nginx配置php比较费劲，最后用apache解决了。
[root@discuz ~]# rpm -ivh Fedora/epel/6/i386/epel-release-6-8.noarch.rpm
[root@discuz ~]# wget
[root@discuz ~]# rpm --import RPM-GPG-KEY-EPEL-6
[root@discuz ~]# wget
[root@discuz ~]# tar zxvf libiconv-1.14.tar.gz
[root@discuz ~]# cd libiconv-1.14
[root@discuz libiconv-1.14]# ./configure --prefix=/usr/local
[root@discuz libiconv-1.14]# make
[root@discuz libiconv-1.14]# make install
[root@discuz ~]# setenforce 0
[root@discuz ~]# yum install nginx php mysql-server php-pecl-memcache memcached
[root@discuz ~]# chkconfig --level 345 memcached on
[root@discuz ~]# chkconfig --level 345 mysqld on
[root@discuz ~]# vi /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="256"
OPTIONS=""
[root@discuz ~]# service memcached start
[root@discuz ~]# service mysqld start
[root@discuz ~]# mysqladmin -u root password 'your_password'
[root@discuz ~]# vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
[root@discuz ~]# reboot
[root@discuz ~]# wget
[root@discuz ~]# yum install unzip
[root@discuz ~]# mkdir discuz
[root@discuz ~]# unzip Discuz_X2.5_SC_UTF8.zip -d discuz
[root@discuz ~]# yum erase nginx
[root@discuz ~]# chkconfig --level 345 httpd on
[root@discuz ~]# service httpd start
[root@discuz ~]# cp -r /opt/discuz /var/www/html/
start in Firefox
./config 不可写
./data 不可写
./uc_client 不可写
./uc_server 不可写
mysql_connect() 不支持 请检查 mysql 模块是否正确加载
[root@discuz ~]# chown -R apache:apache /var/www/html/discuz/data
[root@discuz ~]# chown -R apache:apache /var/www/html/discuz/config
[root@discuz ~]# chown -R apache:apache /var/www/html/discuz/uc_client
[root@discuz ~]# chown -R apache:apache /var/www/html/discuz/uc_server
[root@discuz ~]# yum install php-mysql
[root@discuz ~]# service httpd restart
