MySQL Turn on remote access

1.mysql-server only allow native (localhost, 127.0.0.1) to connect access for security reasons. This is not a problem for the site architecture of Web-server and Mysql-server on the same server. However, as the site traffic increases, the late server architecture may place web-server and mysql-server on separate servers for greater performance, at which point Mysql-server is modified to allow web-server remote connections.

2. Do not log on to the server every time to add the modified table, as long as the graphical interface can be remotely managed.

We can modify the following steps as follows:
1, login mysql-server to connect to local Mysql (only local connection is allowed by default)

2. Modify Mysql-server User Configuration

mysql> use MySQL;--switch to MySQL dbdatabase changedmysql> SELECT user, Password, Host from user;--View existing user, password and allow connection Host +------+----------+-----------+| User | Password | Host |+------+----------+-----------+|          Root | | localhost |+------+----------+-----------+1 row in Set (0.00 sec) Mysql>--only one default root user, password is empty, only localhost connection 12mys is allowed Ql>--Below we add a new root user, password is empty, only allow 192.168.1.100 connection mysql> GRANT all privileges on * * to ' root ' 192.168.1.1 "Identified by" with GRANT OPTION; Mysql>-- @ ' 192.168.1.100 ' can be replaced by the @ '% ' to any IP access , of course, we can also update the root user Host directly with update, but not recommended, SQL is as follows:mysql>-Updat E user SET host= ' 192.168.1.100 ' WHERE user= ' root ' and host= ' localhost ' LIMIT 1;
mysql> flush privileges;

Change Root password

mysql> use mysql
Database changed


mysql> update user setpassword=PASSWORD(‘123456‘) whereuser=‘root‘;
