1.Update source
yum update
2.Install nginx
yum install nginx
3. Start nginx
service nginx start

5. Install mysql:
Install mysql source yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7. noarch.rpm
Installation: yum install mysql mysql-server
Start: /etc/init.d/mysqld start or service mysqld restart
Reset password :mysql -u root -p
Chance of error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Reason: Permission problem
Solution: sudo chown -R root:root /var/lib/mysql (Both roots can be changed to owners, but they need to be consistent)
Restart service
service mysqld restart
Log in to mysql
mysql -u root -p // Press Enter to log in directly. There is no password for mysql just after installing it
Modify mysql password
Use mysql;
Modify earlier versions: update user set password =password('your password') where user='root';
High version modification: update user set authentication_string = password('your password'), password_expired = 'N', password_last_changed = now( ) where user = 'root';
alter user 'root'@'localhost' identified by 'your password';
If the password is not strong enough, you can check the password level: SHOW VARIABLES LIKE "%password%" ;
Then set to low level: SET GLOBAL validate_password_policy=0;
Finally exit;
exit;
Restart service mysqld restart
Allow remote access
1 .Add the following command line if necessary to add remote connection capabilities to root. The link password is 'your password'
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
