安装MySQL和phpMyAdmin记

安装phpMyAdmin,遇到几个问题，记录一下要点：

安装phpMyAdmin
解压到/var/www
配置Apache
Listen 8030
<VirtualHost *:8030>
DocumentRoot /var/www/phpMyAdmin
</VirtualHost>

cp config.sample.inc.php config.inc.php
vi config.inc.php
修改以下段
/*
* First server
*/
$i++;
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
/* Server parameters */
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysqli if your server has it */
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

连接多个host，复制上面一段，改变一下$cfg['Servers'][$i]['host']即可，
在登录的时候会多亿个host选择框。

RedHat php升级到5.2

default-character-set=utf8
default-character-set=utf8
[mysqld]
datadir         = /opt/mysql_data
default-character-set=utf8

增加mysql用户

赋执行权限
chomd +x /etc/init.d/mysql

启动mysql
service mysql restart
