[Nginx] install the lnmp environment in centos6.5

[Nginx] install the lnmp environment in centos6.5

 

Preface

I haven't written a blog for a long time. It's really bad. I feel more and more things are coming into contact. If I don't record them, I will slowly forget them. Because of service requirements, apache's load capacity can no longer meet the current needs, so we decided to use nginx as the server to carry more interface access.

Preparations

One centos6.5 virtual machine, reinstalled system, nothing else

Nginx update source

Because yum does not support nginx, you need to update it yourself.

Set nginx to start and start the service

 

[Root @ localhost ~] # Chkconfig nginx on [root @ localhost ~] # Service nginx start is starting nginx: [OK]

I tried it. I didn't think it was successful. I didn't configure a firewall. So I stopped the firewall and then restarted nginx.

 

 

[Root @ localhost ~] # Service iptables stopiptables: Set the chain to the policy ACCEPT: filter [OK] iptables: Clear the firewall rule: [OK] iptables: uninstalling the module: [OK] [root @ localhost ~] # Service nginx start [root @ localhost ~] # Service nginx restart stop nginx: [OK] Starting nginx: [OK]

Nginx is installed successfully!

Install MySQL directly on the MySQL client and server

 

[root@localhost ~]# yum install mysql mysql-server

Start the service

 

[Root @ localhost ~] # Service mysqld start initialize MySQL database: Installing MySQL system tables... OKFilling help tables... OKTo start mysqld at boot time you have to copysupport-files/mysql. server to the right place for your systemPLEASE remember to set a password for the MySQL root USER! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin-u root password 'new-password'/usr/bin/mysqladmin-u root-h localhost. localdomain password 'new-password' Alternatively you can run:/usr/bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default. this isstronugly recommended for production serv Ers. see the manual for more instructions. you can start the MySQL daemon with: cd/usr;/usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.plcd/usr/mysql-test; perl mysql-test-run.plPlease report any problems with the/usr/bin/mysqlbug script! [OK] Starting mysqld: [OK]

Set to start mysql at startup and back up the configuration file

 

[Root @ localhost ~] # Chkconfig mysqld on [root @ localhost ~] # Cp/usr/share/mysql/my-medium.cnf/etc/my. cnfcp: overwrite "/etc/my. cnf "? Y

Set the root user password

 

[root@localhost ~]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!In order to log into MySQL to secure it, we'll need the currentpassword for the root user.  If you've just installed MySQL, andyou haven't set the root password yet, the password will be blank,so you should just press enter here.Enter current password for root (enter for none):OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MySQLroot user without the proper authorisation.Set root password? [Y/n] yNew password:Re-enter new password:Password updated successfully!Reloading privilege tables.. ... Success!By default, a MySQL installation has an anonymous user, allowing anyoneto log into MySQL without having to have a user account created forthem.  This is intended only for testing, and to make the installationgo a bit smoother.  You should remove them before moving into aproduction environment.Remove anonymous users? [Y/n] ... Success!Normally, root should only be allowed to connect from 'localhost'.  Thisensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] ... Success!By default, MySQL comes with a database named 'test' that anyone canaccess.  This is also intended only for testing, and should be removedbefore moving into a production environment.Remove test database and access to it? [Y/n] - Dropping test database... ... Success! - Removing privileges on test database... ... Success!Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] ... Success!Cleaning up...All done!  If you've completed all of the above steps, your MySQLinstallation should now be secure.Thanks for using MySQL!

Restart mysql

 

[Root @ localhost ~] # Service mysqld restart stop mysqld: [OK] Starting mysqld: [OK]

 

Install PHP and install php-fpm

As a server, Nginx does not support php. We need a php-fpm to support php parsing.

[root@localhost ~]# yum install php php-fpm

Install php Extension

 

[root@localhost ~]# yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

Several extensions are not installed. Please note!

 

 

Setting up Install ProcessNo package php-mcrypt available.No package php-mhash available.No package libmcrypt available.

Start php-fpm and php-fpm

 

[Root @ localhost ~] # Chkconfig php-fpm on [root @ localhost ~] # Service php-fpm start is starting php-fpm: [OK]

Save

Modify php-fpm Configuration

Back up the configuration file and modify it.

Test

 

Write the test file in the directory where nginx is located, Set permissions, and restart nginx and php-prm
