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:
2017-04-09 22:38:20 [WARNING] 2017-04-10T05:38:12.530858Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead

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

2017-04-10T06:12:09.706181Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

  • 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()";
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
至此mysql 5.7.17安装完成。
