The 17th Chapter LNMP the environment to build

Unlike lamp, the N in Lnmp refers to the Nginx (a Web service software similar to Apache). At present this kind of environment application is also very many. Nginx Design is designed to provide a fast and efficient and multiple concurrent Web services software. In the static page processing Nginx really wins Apache, however, in the dynamic page processing Nginx no more than Apache advantages. However, there are still many enthusiasts are more enthusiastic about nginx, with the Nginx technology gradually mature, it in the field of Web services software more and more high.

"MySQL Installation"

1. Download MySQL to/usr/local/src/

cd/usr/local/src/

wget http://syslab.comsenz.com/downloads/linux/mysql-5.0.86-linux-i686-icc-glibc23.tar.gz

2. Decompression

Tar zxvf/usr/local/src/mysql-5.0.86-linux-i686-icc-glibc23.tar.gz

3. Move the extracted data to the/usr/local/mysql

MV Mysql-5.0.86-linux-i686-ii-glibc23/usr/local/mysql

4. Establish MySQL User

Useradd MySQL

5. Initializing the database

Cd/usr/local/mysql

Mkdir/data/mysql; Chown-r Mysql:mysql/data/mysql

./scripts/mysql_install_db--user=mysql--datadir=/data/mysql

--user defines the owner of the database,--datadir defines where the database is installed, and recommends placing it on a large-space partition that needs to be created by itself.

6. Copy configuration file

CP SUPPORT-FILES/MY-LARGE.CNF/ETC/MY.CNF

7. Copy startup script file and modify its properties

CP Support-files/mysql.server/etc/init.d/mysqld

chmod 755/etc/init.d/mysqld

8. Modify the startup script

Vim/etc/init.d/mysqld

Where you need to modify is Datadir=/data/mysql (the directory defined before initializing the database)

9. Add the boot script to the system service and set boot up and start MySQL

Chkconfig--add mysqld

Chkconfig mysqld on

Service mysqld Start

If it does not start, check the error log under/data/mysql/, which is the hostname. Err.

" installation of PHP"

Here to declare, for nginx PHP installation and for the Apache PHP installation is a difference, because Nginx PHP is fastcgi way to combine nginx, can be understood as nginx agent of PHP fastcgi, And Apache is the use of PHP as its own module to invoke.

Download the second package php-5.2.10-fpm-0.5.13.diff.gz is used to patch PHP, by default, PHP is unable to compile the fastcgi.

"nginx Installation and Configuration "

1. Nginx Source code installation

cd/usr/local/src/

wget http://syslab.comsenz.com/downloads/linux/nginx-0.9.6.tar.gz

Tar zxvf nginx-0.9.6.tar.gz

CD nginx-0.9.6

./configure--prefix=/usr/local/nginx--sbin-path=/usr/local/nginx/sbin/nginx--conf-path=/usr/local/nginx/conf/ nginx.conf--error-log-path=/usr/local/nginx/logs/error.log--http-log-path=/usr/local/nginx/logs/access.log-- Pid-path=/usr/local/nginx/var/nginx.pid--lock-path=/usr/local/nginx/var/nginx.lock--http-client-body-temp-path =/dev/shm/nginx_temp/client_body--http-proxy-temp-path=/dev/shm/nginx_temp/proxy--http-fastcgi-temp-path=/dev/ shm/nginx_temp/fastcgi--user=www--group=www--with-cpu-opt=pentium4f--without-select_module--without-poll_ Module--with-http_realip_module--with-http_sub_module--with-http_gzip_static_module--with-http_stub_status_ Module--without-http_ssi_module--without-http_userid_module--without-http_geo_module--without-http_memcached_ Module--without-http_map_module--without-mail_pop3_module--without-mail_imap_module--without-mail_smtp_module- -with-pcre

Make && make install

Mkdir/dev/shm/nginx_temp

Some nginx version will be compiled because Pcre compiler, need to modify the--with-pcre=/usr/local/src/pcre-7.8, provided that the PCRE source package has been downloaded pcre-7.8.tar.gz, and extracted to the/usr/ local/src/pcre-7.8, no need to compile Pcre

2. write nginx startup scripts and join the system services

Vi/etc/init.d/nginx writes the following:

#!/bin/bash
# Chkconfig:-30 21
# Description:http Service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
Nginx_sbin= "/usr/local/nginx/sbin/nginx"
nginx_conf= "/usr/local/nginx/conf/nginx.conf"
Nginx_pid= "/usr/local/nginx/var/nginx.pid"
Retval=0
Prog= "Nginx"
Start () {
Echo-n $ "Starting $prog:"
Mkdir-p/dev/shm/nginx_temp
Daemon $NGINX _sbin-c $NGINX _conf
Retval=$?
Echo
Return $RETVAL
}
Stop () {
Echo-n $ "Stopping $prog:"
Killproc-p $NGINX _pid $NGINX _sbin-term
Rm-rf/dev/shm/nginx_temp
Retval=$?
Echo
Return $RETVAL
}
Reload () {
Echo-n $ "Reloading $prog:"
Killproc-p $NGINX _pid $NGINX _sbin-hup
Retval=$?
Echo
Return $RETVAL
}
Restart () {
Stop
Start
}
Configtest () {
$NGINX _sbin-c $NGINX _conf-t
return 0
}
Case "$" in
Start
Start
;;
Stop
Stop
;;
Reload
Reload
;;
Restart)
Restart
;;
Configtest)
Configtest
;;
*)
echo $ "Usage: $ {start|stop|reload|restart|configtest}"
Retval=1
Esac

Exit $RETVAL

After saving, change the permissions of the/etc/init.d/nginx

chmod 755/etc/init.d/nginx

Chkconfig--add Nginx

Chkconfig Nginx on

3. configuration of Nginx

Vim/usr/local/nginx/conf/nginx.conf

Empty the original file and paste the following:

User www www.

Worker_processes 2;

Error_log/usr/local/nginx/logs/nginx_error.log Crit;

}

}

}

After you save it, you can start Nginx, and before you reboot, it's a good idea to check for problems.

/USR/LOCAL/NGINX/SBIN/NGINX-T If you display information such as "syntax is OK and nginx.conf was tested successfully," The configuration is no problem, otherwise you will need to modify it as prompted.
Service Nginx Start

If not, please check the Nginx_error.log log file in the/usr/local/nginx/logs/directory. If you do not have this log file, it is most likely that the directory does not write permissions, please perform

chmod +w/usr/local/nginx/logs/
Service Nginx Restart

Refer to the following posts for detailed configuration of the Nginx configuration file:

Nginx Main configuration file
Nginx Virtual Host configuration file
