一、解压tar包
#tar zxvf mysql-5.6-linux-glibc2.5-x86_64.tar.gz
改名
#mv mysql-5.6-linux-glibc2.5-x86_64 mysql二、创建用户
#useradd mysql
#passwd mysql
三、修改目录权限
#chown -R mysql:mysql mysql#su - mysql
四、创建参数文件（路径修改成自己的）
#vi my.cnf
复制粘贴以下内容到my.cnf文件中
##===========================================================

五、初始化，初始化mysql表、test表、infomation表等
#scripts/mysql_install_db --user=mysql --basedir=/opt/mysql --datadir=/opt/mysql/data
六、创建日志目录
#cd /opt/mysql
#mkdir logs/
七、启动服务(必须在mysql家目录下启动)
#/opt/mysql/bin/mysqld_safe --defaults-file=/opt/mysql/my.cnf
后台启动服务
#/opt/mysql/bin/mysqld_safe --defaults-file=/opt/mysql/my.cnf &
八、进入mysql客户端
#/opt/mysql/bin/mysql -uroot -p -S /opt/mysql/mysql.sock
mysql>show databases;
九、退出mysql
mysql>exit;
十、关库并停止服务
#/opt/mysql/bin/mysqladmin -uroot -p -S /opt/mysql/mysql.sock shutdown
