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/

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

[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

[root@VMOS01 init.d]# service mysql.server start

  • 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()";
