添加用户和分组

useradd -r -g mysql mysql

配置与初始化
cd /software/installed/mysql/
chown -R mysql:mysql .
chown -R mysql:mysql /usr/local/mysql/data
cp support-files/my-large.cnf /etc/my.cnf //增加配置文件
cp support-files/mysql.server /etc/init.d/mysql //加入service
scripts/mysql_install_db --datadir=/usr/local/mysql/data --user=mysql --basedir=/software/installed/mysql
启动mysql
service mysql start

为root设置密码

设置PATH
vi /etc/profile
在文件末尾加上
PATH=/software/installed/mysql/bin:$PATH
export PATH
source /etc/profile

mysql -uroot
mysql> SET PASSWORD = PASSWORD('mysqlroot123456');
设置远程可以访问
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.%' IDENTIFIED BY 'mysql123456' WITH GRANT OPTION;
eixt;

配置iptables 3306端口通过
vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
service iptables restart

关闭mysql DNS反向解析，

MySQL数据库收到一个网络连接后，首先拿到对方的IP地址，然后对这个IP地址进行反向DNS解析从而得到这个IP地址对应的主机名。用主机名在权限系统里面进行权限判断。反向DNS解析是耗费时间的，有可能让用户感觉起来很慢。甚至有的时候，反向解析出来的主机名并没有指向这个IP地址，这时候就无法连接成功了。 

只需在my.cnf的[mysqld]段落中加入如下行即可：

skip-name-resolve
