作者：登峰小蚁
这篇文章主要为大家详细介绍了Ubuntu18.04安装mysql5.7.23的教程，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文为大家分享了Ubuntu18.04安装mysql5.7.23的具体方法，供大家参考，具体内容如下
1、安装服务器和客户端
# 安装mysql服务 sudo apt-get install mysql-server # 安装客户端 sudo apt install mysql-client # 安装依赖 sudo apt install libmysqlclient-dev
2、检查安装状态
# 检查状态 sudo netstat -tap | grep mysql
出现下图表示安装成功
3、安装完以后配置
mysql5.7安装完成后普通用户不能进mysql，原因：root的plugin被修改成了auth_socket，用密码登陆的plugin应该是mysql_native_password，直接用root权限登录就不用密码,修改root密码和登录验证方式
$ sudo su
# mysql
mysql>
mysql> select user, plugin from mysql.user;
+------------------+-----------------------+
| user | plugin |
+------------------+-----------------------+
| root | auth_socket |
| mysql.session | mysql_native_password |
| mysql.sys | mysql_native_password |
| debian-sys-maint | mysql_native_password |
+------------------+-----------------------+
4 rows in set (0.00 sec)
mysql> update mysql.user set authentication_string=PASSWORD('123456'), plugin='mysql_native_password' where user='root';
mysql> flush privileges;
mysql> exit
Bye
# exit
$ sudo /etc/init.d/mysql restart
$ mysql -uroot -p
Enter password:
