Linux 设置远程连接,并添加远程连接用户(10038)

1:配置mysql服务器

# 1.更改配置文件

#因为远程mysql服务器,设置只监听本地的端口,更改mysql配置文件,注释掉下面的一行。打开远程服务器的配置文件.

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf # 注释下面一行。
# bind-address = 127.0.0.1
# 如果没注释上面的一行,客户端连接时,会出现如下错误。
ERROR 2003 (HY000): Can't connect to MySQLserver on '192.168.1.249' (111)

# 2. 打开mysql服务

sudo service /etc/init.d/mysql start
