在CentOS6上安装Discuz! X2.5

简明过程
1. 参考 http://www.discuz.net/thread-1833489-1-1.html
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 http://mirrors.ustc.edu.cn/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
[root@discuz ~]# wget http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6
[root@discuz ~]# rpm --import RPM-GPG-KEY-EPEL-6
[root@discuz ~]# wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
[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 http://download2.comsenz.com/DiscuzX/2.5/Discuz_X2.5_SC_UTF8.zip
[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/

[root@discuz ~]# chown -R apache:apache /var/www/html/discuz/uc_server
[root@discuz ~]# yum install php-mysql
[root@discuz ~]# service httpd restart

Is this ok [y/N]:


7.查看php版本
[root@discuz ~]# php -v
PHP 5.3.3 (cli) (built: Jul  3 2012 16:53:21)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
[root@discuz ~]#

【ZendOptimizer？ 只有Zend Optimizer (Runtime for PHP 5.2 and earlier)，是不是php5.3不用Zend Optimizer了？？】


8.配置服务
[root@discuz ~]# chkconfig --level 345 memcached on
[root@discuz ~]# chkconfig --level 345 nginx 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
Starting memcached:

[root@discuz ~]# service nginx start
Starting nginx:                                            [  OK  ]

[root@discuz ~]# service mysqld start
Initializing MySQL database:  WARNING: The host 'discuz.flysky.intra' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h discuz.flysky.intra password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

[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
