所有的安裝包可以去以下地址下載，或者自行去官網(wǎng)下載，下面都有介紹.
所有安裝包地址：http://download.csdn.net/detail/carboncomputer/9238037
原文地址：http://www.cnblogs.com/zhongshengzhen/p/nginx.html
1、下載PCRE， 是一個用C語言編寫的正則表達式函數(shù)庫 [root@localhost pcre-8.36]# cd /tmp/download/
[root@localhost download]# wget http://nchc.dl./project/pcre/pcre/8.37/pcre-8.37.tar.gz
[root@localhost download]# tar zxvf pcre-8.36.tar.gz
2、下載zlib庫
[root@localhost pcre-8.36]# cd /tmp/download/
[root@localhost download]# wget http://ncu.dl./project/libpng/zlib/1.2.8/zlib-1.2.8.tar.gz [root@localhost download]# tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
4、下載SSL [root@localhost zlib-1.2.8]# cd ..
[root@localhost download]# wget http://www./source/openssl-1.0.1p.tar.gz [root@localhost download]# cd openssl-1.0.1c
[root@localhost openssl-1.0.1c]# tar -zxvf openssl-1.0.1c.tar.gz
5、下載nginx
[root@localhost download]# wget http:///download/nginx-1.2.8.tar.gz
[root@localhost download]# tar -zxvf nginx-1.2.8.tar.gz
6、安裝
[root@localhost download]mv pcre-8.36 /usr/local/
[root@localhost download]mv zlib-1.2.8 /usr/local/
[root@localhost download]mv openssl-1.0.1c /usr/local/
[root@localhost download]mv nginx-1.2.8 /usr/local/
[root@localhost download]cd /usr/local/
[root@localhost local]# cd pcre-8.36
[root@localhost pcre-8.36]# ./configure&&make&&make install
[root@localhost pcre-8.36] cd ../zlib-1.2.8
[root@localhost zlib-1.2.8]# ./configure && make && make install
[root@localhost zlib-1.2.8]# cd ../openssl-1.0.1c
[root@localhost openssl-1.0.1c]# ./config && make && make install
[root@localhost openssl-1.0.1c]# cd ../nginx-1.2.8
[root@localhost nginx-1.2.8]# ./configure --prefix=/usr/local/nginx && make && make install
7、啟動nginx
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
8、測試
在確?？梢赃B接到服務(wù)器的電腦上，瀏覽器輸入裝了nginx的機器的ip地址，會看到Welcome to nginx!的提示說明安裝配配置成功了。
 9、設(shè)置開機自動啟動（shell腳本處理）
[root@localhost logs]# vi /etc/init.d/nginx
添加以下shell腳本。
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server # it is v.0.0.2 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it's not for everyone. # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf nginxd=/usr/local/nginx/sbin/nginx nginx_config=/usr/local/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid RETVAL=0 prog="nginx" # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x $nginxd ] || exit 0 # Start nginx daemons functions. start() { if [ -e $nginx_pid ];then echo "nginx already running...." exit 1 fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL } # Stop nginx daemons functions. stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid } # reload nginx service functions. reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo } # See how we were called. case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $RETVAL 保存后，設(shè)置權(quán)限讓所有人可以操作。
[root@localhost ~]# chmod a+x /etc/init.d/nginx
[root@localhost logs]# /etc/init.d/nginx status
nginx (pid 2417 2416) is running... [root@localhost logs]# /etc/init.d/nginx stop Stopping nginx: [ OK ] [root@localhost logs]# /etc/init.d/nginx start Starting nginx: [ OK ] [root@localhost logs]# /etc/init.d/nginx status nginx (pid 2454 2452) is running... [root@localhost ~]# vi /etc/rc.local
添加：
/etc/init.d/nginx start
重啟電腦就會生效。
注意：腳本里面關(guān)于啟動目錄的，如果你的安裝地址不一樣，要進行修改。
負載均衡配置：
現(xiàn)有兩部服務(wù)器：
192.168.137.197 （按照以上操作安裝有nginx，作為轉(zhuǎn)發(fā)機，虛擬機）
192.168.137.33 （無安裝nginx，運行有測試用的web工程，虛擬機）
10.10.33.59 （無安裝nginx，運行有測試用的web工程，本地電腦地址）
，運行有測試用的web工程
127.0.0.1 web_app
[root@a conf]# vi /usr/local/nginx/conf/nginx.conf
配置如下展示：
worker_processes 8;
pid /usr/local/nginx/nginx.pid; worker_rlimit_nofile 102400; events { use epoll; worker_connections 102400; } http { include mime.types; default_type application/octet-stream; fastcgi_intercept_errors on; charset utf-8; server_names_hash_bucket_size 128; client_header_buffer_size 4k; large_client_header_buffers 4 32k; client_max_body_size 300m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; client_body_buffer_size 512k; proxy_connect_timeout 5; proxy_read_timeout 60; proxy_send_timeout 5; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; gzip on;

[root@a conf]# vi /etc/hosts
添加hosts：
127.0.0.1 web_app
啟動nginx
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
啟動三部服務(wù)器的web應(yīng)用：
在192.168.137.197執(zhí)行指令：
[root@a PROGRAM]# curl "http://web_app/index.jsp"
測試結(jié)果如下：
 常見問題及解決辦法：
1、安裝PCRE時提示configure: error: You need a C++ compiler for C++ support.
原因是沒有安裝c++編譯器，采用下面的命令安裝：
[root@localhost pcre-8.37]# yum install -y gcc gcc-c++
2、啟動nginx失敗
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory 原因是64bit的系統(tǒng)，但是默認(rèn)取了/usr/local/lib里面的包
檢查方法：
[root@localhost nginx]# cd /usr/local/
[root@localhost local]# ls /lib64/ |grep pcre
libpcre.so.0 libpcre.so.0.0.1 [root@localhost local]# ls /lib/ |grep pcre 說明缺失的包在lib64
設(shè)置軟連接來解決：
[root@localhost local]# ln -s /lib64/libpcre.so.0.0.1 /lib64/libpcre.so.1
[root@localhost local]# cd nginx [root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf 3、啟動報錯：
報錯：nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
解決辦法：sudo fuser -k 80/tcp
端口被占用，關(guān)閉占用端口
