CentOS 6.5 installation and configuration LNMP server (Nginx+PHP+MySQL)

Build an LNMP server under CentOS and take notes after practicing.

Preparation

Configure the firewall and open port 80 and 3306

vi /etc/sysconfig/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport   80    -j ACCEPT   #Allow port 80 through the firewall -A INPUT -m state --state NEW -m tcp -p tcp --dport   3306    -j ACCEPT   #Allow port 3306 through the firewall  /etc/init.d/iptables restart #Finally restart the firewall to make the configuration take effect

If that fails, you can use:

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport  80    -j ACCEPT  

Close SELINUX

vi /etc/selinux/config #SELINUX=enforcing #Comment out #SELINUXTYPE=targeted #Comment out SELINUX=disabled  #Increase :wq    #Save and exit  shutdown -r now #Restart the system

Install third-party yum source

wget http://www.atomicorp.com/installers/atomic  #download sh ./atomic  #Install yum check-update  #Update yum source

Installation

Install nginx

yum remove httpd* php*  #Delete the software package that comes with the system yum install nginx  #Install nginx Enter y according to the prompt to install chkconfig nginx on  #Set nginx to start at boot service nginx start  #Start nginx

InstallMySQL

• InstallMySQL

yum install mysql mysql-server  #Enter Y to automatically install until the installation is completed /etc/init.d/mysqld start   #StartMySQL chkconfig mysqld on  #Set to start at boot cp /usr/share/mysql/my-medium.cnf /etc/my.cnf  #Copy the configuration file (note: if there is a my.cnf by default under the /etc directory, just overwrite it directly)

• Set password for root account

mysql_secure_installation

Enter Y according to the prompts, enter the password twice, press Enter, enter Y all the way according to the prompts, and finally appear: Thanks for using MySQL!
MySql password setting is completed, restart MySQL:

/etc/init.d/mysqld restart  #restart /etc/init.d/mysqld stop  #stop /etc/init.d/mysqld start   #start up

Install PHP5

• Install PHP5

  yum install php php-fpm #Enter Y according to the prompts until the installation is completed

• Install PHP components so that PHP5 supports MySQL
  

  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 #Select the above installation package to install, enter Y according to the prompts and press Enter chkconfig php-fpm on #Set php-fpm to start at boot /etc/init.d/php-fpm start #Start php-fpm

Configuration

• Configure nginx to support php

cp /etc/nginx/nginx.conf /etc/nginx/nginx.confbak  #Back up the original configuration file vi /etc/nginx/nginx.conf  #edit user nginx nginx;  #Modify the nginx running account to: nginx user of the nginx group :wq    #Save and exit 

cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.confbak  #Back up the original configuration file vi /etc/nginx/conf.d/default.conf  #edit index index.php index.html index.htm;  #Add index.php # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { roothtml; fastcgi_pass  127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name; include fastcgi_params; } #Uncomment the location of the FastCGI server part, and pay attention to the parameters of the fastcgi_param line, change it to $document_root$fastcgi_script_name, or use an absolute path

service nginx restart #Restart nginx

• php configuration

vi /etc/php.ini  #edit date.timezone = PRC  #Remove the semicolon in front and change it to date.timezone = PRC disable_functions  =passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space ,posix_ctermid,posix_get_last_error,posix_getcwd,posix_getegid,posix_geteuid,posix_getgid,posix_getgrgid,posix_getgrna m,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid,posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty,posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid,posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname #On line 386, list the functions that can be disabled in PHP. If some programs need to use this function, it can be deleted and undisabled. expose_php = Off  #Suppress display of php version information short_open_tag = ON  #Support php short tags open_basedir = website root directory:/tmp/ #Setting means allowing access to the current directory (that is, the directory where the PHP script file is located) and the /tmp/ directory; the colon is the separator. :wq!   #Save and exit 

Some tutorials in the open_basedir configuration option will be configured asopen_basedir=.:/tmp/, where '.' represents the current directory. This method does not seem to work under nginx+phpfastcgi.

• Configure php-fpm

cp /etc/php-fpm.d/www.conf /etc/php-fpm.d/www.confbak  #Back up the original configuration file vi /etc/php-fpm.d/www.conf  #edit user=nginx  #Modify user to nginx group=nginx  #Modify the group to nginx :wq    #Save and exit 

Test article

cd  /usr/share/nginx/html vi index.php  #Add the following code  phpinfo(); ?> :wq!   #Save and exit  chown nginx.nginx /usr/share/nginx/html -R  #Set permissions service nginx restart  #Restart nginx service php-fpm restart  #restartphp-fpm

Enter the server IP address in the client browser and you can see the relevant configuration information! It means lnmp configuration is successful!

At this point, the CnetOS 6.5 installation and configuration LNMP (Nginx+PHP+MySQL) tutorial is completed.
