Ubuntu安装mysql

1、安装mysql

#此命令直接安装最新版mysql8.0
sudo apt-get install mysql-server

2、查看默认用户及密码

cat /etc/mysql/debian.cnf

user	=debian-sys-maint
password	=s8hjWltF0W2EBU32

3、登录该用户

mysql -u debian-sys-maint -p
use mysql;
update user set plugin = 'mysql_native_password' where user = 'root';
alter user 'root'@'localhost' identified by 'wo990414';

flush privileges;
exit
service mysql restart

mysql -u root -pwo990414

4、修改访问权限

select user,host from user;
update user set host='%' where user='root';
exit
service mysql restart

5、修改配置文件，支持远程访问

vim /etc/mysql/mysql.conf.d/mysqld.cnf
...
bind-address            = 0.0.0.0
mysqlx-bind-address     = 0.0.0.0
...

service mysql restart

6、防火墙放行3306端口

ufw enable
ufw status
ufw allow 3306
ufw reload

7、服务器安全组添加3306规则，便可远程连接服务器的数据库了

1、执行安装命令

apt-get install openjdk-8-jdk

                server_name localhost;

                }
	...
}

2、重启nginx服务器

service nginx restart

2、防火墙放行6868端口
