安装Mysql

• 1)安装

apt install default-mysql-server 

• 2)初始化数据库

mysql_install_db  

• 3)启动mysql

service mysql start  

• 4)修改root用户密码

/usr/bin/mysqladmin -u root password '1234'  # 这里用的密码是1234，可自行更改成其他的密码

• 5)登录mysql

mysql -u root -p1234  # 密码自行更改

• 6)开启root用户远程访问权限(自行更改密码)

# 写入权限
grant all on *.* to root@'%' identified by '1234' with grant option;
# 刷新权限并退出  
flush privileges;
quit;

• 7)修改配置文件
  进入full screen 模式 --> 打开配置文件 --> i 插入 --> 更改bind-address --> ES返回 --> :wq保存并退出

# 打开配置文件
vim /etc/mysql/mariadb.conf.d/50-server.cnf  

# 更改bind-address
bind-address=0.0.0.0

• 8)重启mysql

kill -9 `pgrep mysql`

 # 问题一:每次启动都会报错.回车一下就行(有没有大佬知道怎么解决的QAQ)
# 问题二:不能自动启动
