下载rpm安装包
Mysql官网:https://dev.mysql.com/downloads/mysql/
选择版本下载:
可以使用wget命令下载:
[root@localhost opt]#wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.20-1.el6.x86_64.rpm-bundle.tar
注意RedHat的版本和系统位数。
查看依赖的库
[root@localhost opt]# yum search libaio [root@localhost opt]# yum install libaio
查看系统之前是否有安装过mysql相关版本
[root@localhost opt]# rpm -qa | grep mysql [root@localhost opt]# rpm -qa | grep mariadb
有则删除,有几个删除几个
[root@localhost opt]# rpm -e mariadb-libs-5.5.44-2.el7.x86_64 --nodeps
安装
按照顺序安装软件包
[root@localhost opt]# rpm -ivh mysql-community-common-5.7.20-1.el6.x86_64.rpm [root@localhost opt]# rpm -ivh mysql-community-libs-5.7.20-1.el6.x86_64.rpm [root@localhost opt]# rpm -ivh mysql-community-client-5.7.20-1.el6.x86_64.rpm [root@localhost opt]# rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm
创建mysql用户和用户组
[root@localhost /]# groupadd mysql [root@localhost /]# useradd -r -g mysql -s /bin/false mysql
创建mysql数据存放目录
[root@localhost /]# mkdir -p /data/mysql [root@localhost /]# chown mysql.mysql /data/mysql [root@localhost /]# ll -d /data/mysql/ drwxr-xr-x. 2 mysql mysql 6 9月 17 17:37 /data/mysql/
修改/etc/my.cnf配置文件
[mysqld] init-connect='SET NAMES utf8mb4' default-storage-engine=INNODB character-set-server=utf8mb4 datadir=/data/mysql socket=/var/lib/mysql/mysql.sock assorted security risks symbolic-links=0 log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid validate_password=off sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION lower_case_table_names=1 [mysql] default-character-set = utf8mb4 [client] default-character-set = utf8mb4
初始化mysql
[root@localhost /]# /usr/sbin/mysqld --initialize --user=mysql
查看初始化密码
[root@localhost /]# grep "root@localhost" /var/log/mysqld.log
登录mysql并修改密码
mysql> set password = password('123456');
允许远程访问(不推荐)
mysql> use mysql; mysql> select host,user,password from user; mysql> update user set password=password('xxxxxx') where user='root'; mysql> update user set host='%' where user='root' and host='localhost'; mysql> flush privileges;
