LNMP Environment Construction--nginx Chapter

1.Nginx configuration file Test

root@kallen:/usr/local/nginx/sbin# nginx -t nginx:nginx: configuration file /etc/nginx/nginx.conf test is successful

2.Nginx Boot

[root@kallen ~]# /usr/local/nginx/sbin/nginx 

3.Nginx Load Balancing

Nginx's upstream currently supports 4 different ways of distribution--

(1) Polling (default):

Each request is assigned to a different back-end server in chronological order, and can be automatically rejected if the backend server is down.

(2) Weight:

Specifies the polling probability, proportional to the weight and access ratios, for situations where the performance of the backend server is uneven.

(3) Ip_hash:

Each request is allocated according to the hash result of the access IP, so that each visitor has fixed access to a back-end server that resolves the session issue. You can select the same back-end server for clients in the same Class C address segment, unless that backend server is down for another one.

(4) Fair (third party):

The response time of the back-end server is allocated to the request, and the response time is short of priority allocation.

(5) Url_hash (third party):

Assign requests by the hash result of the access URL so that each URL is directed to the same back-end server, which is more efficient when the backend server is cached.

4.Nginx Installation and Configuration

(1) Nginx source installation

[root@kallen ~]# cd /usr/local/src/

[root@kallen ~]# wget http://syslab.comsenz.com/downloads/linux/nginx-0.9.6.tar.gz[root@kallen ~]# tar zxvf nginx-0.9.6.tar.gz[root@kallen ~]# 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=/usr/local/src/pcre-8.32/--with-zlib=/usr/local/zlib 

[root@kallen ~]# make && make install [root@kallen ~]# mkdir /dev/shm/nginx_temp

Some of the Nginx version will be compiled because the Pcre compilation does not pass, need to modify
--with-pcre=/usr/local/src/pcre-8.32, the premise is already downloaded Pcre source package pcre-7.8.tar.gz, and extracted to /usr/local/src/pcre-8.32 , do not need to compile pcre.

You may need to manually install the following dependency packages during the actual installation process:

A. Installing dependent software

apt-get--install-suggestsinstallgccg++make

B. Download related software

wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gzwget http://zlib.net/zlib-1.2.8.tar.gzwget http://www.openssl.org/source/openssl-1.0.1g.tar.gzwget http://www.canonware.com/download/jemalloc/jemalloc-3.6.0.tar.bz2wget http://tengine.taobao.org/download/tengine-2.0.2.tar.gz

C. Installing Pcre

  tar zxvf pcre-8.35.tar.gz  cd pcre-8.35 ./configure --prefix=/usr/local/pcre-8.35  make && make install

D. Installing zlib

  tar zxvf zlib-1.2.8.tar.gz  cd zlib-1.2.8  ./configure --prefix=/usr/local/zlib-1.2.8  make && make install

[Error]-1:

The configuration information after the installation is complete is as follows:

(2) Writing Nginx startup script

[root@kallen init.d]# vi /etc/init.d/nginx

Write the following content:

#!/bin/bash#        # Startup script for the Nginx HTTP Server## Kallen Ding, APRNginx_path="/usr/local/nginx/"options="-C ${nginx_path}conf/nginx.conf"prog=nginxnginx=${nginx_path}Sbin/nginxpidfile=/var/run/nginx.pid# Source function library.. /etc/rc.d/init.d/functionsStart() {Echo-N"Starting $prog:"Daemon--pidfile=${pidfile}$nginx$OPTIONSRetval=$?Echoreturn$RETVAL}Stop() {Echo-N"Stopping $prog:"Killproc-p${pidfile}$nginxRetval=$?Echo}Reload() {Echo-N $"Reloading $prog:"Killproc-p${pidfile}$nginx-hup retval=$?Echo}# See how we were called. Case"$"inchStart) Start;  stop) stop;;  restart) stop start;;  reload) reload;; Status) status$progRetval=$?  ;; *)Echo"Usage: $prog {start|stop|restart|reload|status}"Retval=3EsacExit$RETVAL

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

[root@kallen ~]# chmod 755 /etc/init.d/nginx[root@kallen ~]# chkconfig --add nginx[root@kallen ~]# chkconfig nginx on

The above describes the LNMP environment to build--nginx, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
