[root@VMOS01 mysql]# cd /usr/local
[root@VMOS01 local]# mv mysql-advanced-5.7.17-linux-glibc2.5-x86_64 mysql-5.7.17
建立软链接：
[root@VMOS01 local]# ln -s mysql-5.7.17 mysql
[root@VMOS01 local]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
添加MYSQL 运行用户：
[root@VMOS01 local]# useradd -r -M -u 496 -s /sbin/nologin mysql
将软件、目录赋权给运行用户mysql:
[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql-5.7.17/
[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql
[root@VMOS01 local]# chgrp -R mysql /usr/local/mysql-5.7.17/
初始化mysql db:
[root@VMOS01 local]# cd /usr/local/mysql
[root@VMOS01 bin]# cd ..
[root@VMOS01 mysql]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
