ubuntu18.04下安装mariaDB
在windows10中安装了ubuntu18.04，需要安装mariadb
更新源或者替换源
之后进行安装
apt-get install mariadb-server
启动和停止
sudo /etc/init.d/mysql start
sudo /etc/init.d/mysql stop
设置密码
sudo mysql_secure_installation
上面可以配置登录密码，是否允许远程访问等。
后续的一些配置
5.使用navicate远程连接时出现"10061error“
解决方法:
(1） 修改/etc/mysql/my.cnf文件。打开文件，找到下面内容：
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
# 把上面这一行注释掉或者把127.0.0.1换成合适的IP，建议注释掉。
(2）但现在最新版的mariaDB 已将配置文件拆分此时my.cnf文件里面显示如下
!includedir /etc/mysqql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/
# 这两句话的意思是配置文件包含了上面两个文件夹所有的文件，那么现在一一查找bind-address = 127.0.0.1这句话写在哪了。
之后在/etc/mysql/mariadb.conf.d/50-server.cnf此文件下找到bind-address = 127.0.0.1这句话，注释掉就行了。

编辑文件
ubuntu@DESKTOP-22ADTJ6:/etc/mysql/mariadb.conf.d$ sudo vi 50-server.cnf
#bind-address = 127.0.0.1 #注释这行
修改后重启即可

出现这样的提示，应该是mysql的主机设置了访问的主机，需要只需登录主机，只需如下命令即可
sudo mysql -uroot -p
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)
