本文主要是介绍Ubuntu18.04安装mysql5.7.23的教程，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

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: 
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2

mysql>

4、配置mysql远程登录

# 修改配置文件，注释掉bind-address = 127.0.0.1
$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf
 
# 保存退出，然后进入mysql服务，执行授权命令：
$ mysql -uroot -p
 
mysql> grant all on *.* to root@'%' identified by '123456' with grant option;
Query OK, 0 rows affected, 1 warning (0.00 sec)
 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
 
mysql> exit
Bye
$ sudo /etc/init.d/mysql restart
