出发点
因为桥梁我的项目须要用到 MySQL 数据库，想着本人实验室服务器的 MySQL 曾经装好了，就装置 Navicat 筹备近程连贯，通过 shell 进行连贯发现运行失常
mysql -u root -p然而应用 Navicat 连贯时呈现谬误，回绝连贯，于是想到可能 MySQL 不容许近程登录
开启近程 IP 登录许可
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf将 bind-address = 127.0.0.1 后面加上#
lc-messages-dir = /usr/share/mysql
skip-external-locking
#
# 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之后重启 MySQL 即可
/etc/init.d/mysql restart增加用户
开启近程登录之后发现呈现了新的谬误：... is not allowed to connect to this MySql server
于是通过 shell 登录 MySQL，顺次执行以下命令
use mysql;
update user set host=’%’where user=’root’;遂近程连贯胜利
