MYSQL 5.7.17 安装：
软件获取：
官网下载 mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
解压安装：
解压 mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
tar -xvzf mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
将解压的安装文件拷贝到安装目录（可自定义）
[root@VMOS01 mysql]# cp -r mysql-advanced-5.7.17-linux-glibc2.5-x86_64 /usr/local/
[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/
2017-04-09 22:38:11 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld –initialize

mysql5.7 新特性：由上面可以看出， mysql_install_db 已经不再推荐使用了，建议改成 mysqld –initialize 完成实例初始化。
[root@VMOS01 mysql]# ./bin/mysqld –defaults-file=/etc/my.cnf –user=mysql –basedir=/usr/local/mysql/ –datadir=/usr/local/mysql/data/ –initialize

启动 mysql：
[root@VMOS01 support-files]# ./mysql.server start
Starting MySQL SUCCESS!
***
将 mysql 添加到系统服务管理：
[root@VMOS01 support-files]# cp -v mysql.server /etc/init.d
`mysql.server – `/etc/init.d/mysql.server
[root@VMOS01 support-files]# cd /etc/init.d
[root@VMOS01 init.d]# chkconfig –add mysql.server
[root@VMOS01 init.d]# service mysql.server status
SUCCESS! MySQL running (33215)
[root@VMOS01 init.d]# service mysql.server stop
Shutting down MySQL.. SUCCESS!
[root@VMOS01 init.d]# service mysql.server start
Starting MySQL. SUCCESS!
注意点：
编辑 my.cnf 让本地命令行登陆管理 mysql，不会提示找不到 mysql.sock 文件错误：
[root@VMOS01 mysql]# more /etc/my.cnf
[client]
socket=/var/lib/mysql/mysql.sock
[root@VMOS01 init.d]# mysql -uroot -p
Enter password:【输入初始 DB 的密码】
**************************
需要更改 root@localhost 初始密码：
第一次登陆 mysql, 需要更改 root@localhost 密码，否则会出现如下错误：
[root@VMOS01 support-files]# mysql -ur0ot -p
Enter password:
mysql show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
