Mysql > GRANT ALL PRIVILEGES ON *. * TO 'root'@'%' WITH GRANT OPTION;mysql > FLUSH PRIVILEGES

Note: centos7 needs to open the mysql service port in both the CVM management backend and the server firewall. Default is 3306. View the firewall configuration.

Firewall-cmd-permanent-zone=public-add-service=mysqlfirewall-cmd-reload

Connection attempts can be made through remote connection tools such as Navicat, such as connection failure 2003. Unknown error 1006 is a firewall problem. For other problems, you can try to change / etc/my.cnf and restart.

[mysqld] # allows any host to log in to MySQLbind-address = 0.0.0.0port=3306default-authentication-plugin=mysql_native_passwordapache installation

(1) check whether the system has apache installed by default before installation.

Rpm-qa | grep httpd

Delete if any

# Update yum update# installation prerequisite package yum-y install gcc gcc-c++ make# install apacheyum install httpd# apache service enable systemctl start httpd# setup apache boot boot systemctl enable httpd

If not, try changing the vi / etc/httpd/conf/httpd.conf configuration file before restarting

ServerName localhost:80php installation

(1) check whether there are previous files. The default installation of yum is not 7.0. if you try, you need to delete the previous version completely.
