CentOS7安装配置MySQL5.6

安装MySQL

cd /usr/local
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
sudo yum install mysql-server

配置文件

vim /etc/my.cnf

在[mysqld]中添加：

#--------------UTF-8------------------
init-connect='SET NAMES utf8'
character_set_server=utf8
#--------------UTF-8------------------

保存退出

重启mysql

service mysqld restart

发现mysql启动不了，提示：

Job for mysqld.service failed because a timeout was exceeded. See "systemctl status mysqld.service" and "journalctl -xe" for details.

查看下mysql错误日志，

cat /var/log/mysqld.log

发现日志中提示：

[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

解决办法：

mysql_install_db --user=mysql --ldata=/var/lib/mysql/

之后再执行重启命令，启动成功！

登录、修改密码

默认账号root，密码为空
