1.解压MySQL,并拷贝到/application目录下

MySQL-5.7.19-Linux-glibc2.5-x86_64.tar.gz 
tar -zxvf mysql-5.7.19-linux-glibc2.5-x86_64.tar.gz

2.添加MySQL用户

useradd mysql -s -M mysql mysql

3.切换到/application/mysql 改变目录拥有者为MySQL，创建软连接

chown -R mysql.myssql /application/mysql-5.7.19-linux-glibc2.5-x86_64
ln -s /application/mysql-5.7.19-linux-glibc2.5-x86_64 /application/mysql

4.安装MySQL(--basedir mysql基础目录  --datadir mysql数据存放目录)

./bin/mysqld --initialize --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

MySQL二进制安装方式_mysql

5.修改当前目录拥有者为root用户，修改data目录拥有者为MySQL

chown -R mysql:mysql /application/mysql/

6.修改my.cnf

[mysqld]
character-set-server=utf8
datadir=/application/mysql/data
basedir=/application/mysql
socket=/application/mysql/mysql.sock

7.配置my.cnf

cp mysql.server /etc/init.d/mysqld                                           #备份
sed -i 's#/usr/local/mysql#/application/mysql#g' /etc/init.d/mysqld /application/mysql/bin/mysqld_safe   #替换目录

8启动

service mysql start
