連接Mysql報錯lost connection to MySQL server at "waiting for initial communication packet

打開了3306端口，設置了user表host為'%'，依然無法連接，telnet 3306端口不同，原因是配置文件中設置了 bind-address: 127.0.0.1，（/etc/mysql/mysql.conf.d/sqld.cnf ）把他注釋掉，端口能連上，但是又報下面的錯誤

lost connection to MySQL server at "waiting for initial communication packet

在 /etc/mysql/mysql.conf.d/sqld.cnf 文件中增加 skip-name-resolve 就可以連接了
