1. 配置my.cnf

cd /usr/local/mysql/support-files
cp my-default.cnf /etc/my.cnf
vim /etc/my.cnf
=====================================
[client]
#password   = your_password
port        = 3306

default-character-set=utf8

[mysqld]
port        = 3306
socket      = /data/mysql_data/run/mysql.sock
basedir    = /usr/local/mysql
datadir     = /data/mysql_data

2.初始化MYSQL配置表

cd /usr/local/mysql
./scripts/mysql_install_db  --basedir=/usr/local/mysql --datadir=/data/mysql_data/data --user=mysql --force

Installing MySQL system tables...2015-07-30 18:09:19 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2015-07-30 18:09:19 0 [Note] /usr/local/mysql/bin/mysqld (mysqld 5.6.25-73.1-log) starting as process 8165 ...

3.设置开机自启动

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 
chmod +x /etc/init.d/mysql 
chkconfig --add mysql 
chkconfig --level 345 mysql on

4.设置环境变量，方便使用mysql命令

vim /etc/profile
在末尾加入：
PATH=/usr/local/mysql/bin:$PATH  
export PATH  
保存退出后执行：
. /etc/profile  或者  source /etc/profile

5.启动mysql,设置root密码

service mysql start
mysqladmin -uroot password '******'
