2 解压

root用户登陆，上传安装包到服务器
cd /opt
rz
解压
tar -xvf mysql-5.6.41-linux-glibc2.12-x86_64.tar
复制解压后的mysql目录
cd mysql-5.6.41-linux-glibc2.12-x86_64

mkdir /usr/loacl/mysql

cp -r ./* /usr/local/mysql

3 添加用户组和用户

添加用户组
groupadd mysql
添加用户mysql到用户组
useradd -g mysql mysql

4 安装

cd /usr/local/mysql
chown -R mysql:mysql ./
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
cp support-files/mysql.server /etc/init.d/mysql
cp support-files/my-default.cnf /etc/my.cnf    

vi /etc/my.cnf

修改：

basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port=3306
server_id=1
socket=/tmp/mysql.sock

添加：

character_set_server=utf8

加入环境变量，编辑 /etc/profile，这样能够在任何地方用mysql命令了

export PATH=$PATH:/usr/local/mysql/bin
source /etc/profile

启动mysql
service mysql start

修改root密码

mysqladmin -u root password '123456'

测试链接
mysql -u root -p
关闭mysql
service mysql stop
查看运行状态
service mysql status

开机自启动配置
chkconfig --add mysql
chkconfig --list
chkconfig --level 345 mysql on

容许全部外部连接访问

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH PRIVILEGES;
