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

2017-04-09 22:38:20 [WARNING] The bootstrap log isn't empty:

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.

mysql> alter user root@localhost identified by "Root15()";
