需要先裝pcre, zlib，前者為了重寫rewrite，後者為了gzip壓縮。
1.選定源碼目錄
選定目錄 /usr/local/
cd /usr/local/
2.安裝PCRE庫
cd /usr/local/
wget http://exim.mirror.fr/pcre/pcre-8.02.tar.gz
tar -zxvf pcre-8.02.tar.gz
cd pcre-8.02
./configure && make && make install
3.安裝zlib庫
cd /usr/local/
wget http://zlib.net/zlib-1.2.8.tar.gz
tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
./configure
make
make install
4.安裝ssl
cd /usr/local/
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar -zxvf openssl-1.0.1c.tar.gz
./config
make
make install
5.安裝nginx
Nginx 一般有兩個版本，分別是穩定版和開發版，您可以根據您的目的來選擇這兩個版本的其中一個，下面是把 Nginx 安裝到 /usr/local/nginx 目錄下的詳細步驟：
cd /usr/local/
wget http://nginx.org/download/nginx-1.2.8.tar.gz
tar -zxvf nginx-1.2.8.tar.gz
cd nginx-1.2.8
./configure --prefix=/usr/local/nginx
make
make install
--with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源碼路徑。
--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源碼路徑。
6.啟動
確保系統的 80 端口沒被其他程序占用，
/usr/local/nginx/sbin/nginx
檢查是否啟動成功：
netstat -ano|grep 80 有結果輸入說明啟動成功
打開浏覽器訪問此機器的 IP，如果浏覽器出現 Welcome to nginx! 則表示 Nginx 已經安裝並運行成功。
7.重啟
/usr/local/nginx/sbin/nginx –s reload
8.修改配置文件
cd /usr/local/nginx/conf
vi nginx.conf
9.常用配置
#nginx運行用戶和組
user www www;
#啟動進程,通常設置成和cpu的數量相等
worker_processes 4;
#全局錯誤日志及PID文件
pid /var/run/nginx.pid;
error_log /var/log/nginx/error.log;
events {
#epoll是多路復用IO(I/O Multiplexing)中的一種方式,但是僅用於linux2.6以上內核,可以大大提高nginx的性能
use epoll;
#單個後台worker process進程的最大並發鏈接數
worker_connections 10240;
}
#設定http服務器，利用它的反向代理功能提供負載均衡支持
http {
include mime.types;
default_type application/octet-stream;
error_page 400 403 500 502 503 504 /50x.html;
index index.html index.shtml
autoindex off;
fastcgi_intercept_errors on;
sendfile on;
# These are good default values.
tcp_nopush on;
tcp_nodelay off;
# output compression saves bandwidth
gzip off;
#gzip_static on;
#gzip_min_length 1k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_buffers 4 16k;
gzip_proxied any;
gzip_disable "MSIE [1-6]\.";
gzip_types text/plain text/html text/css application/x-javascript application/xml application/xml+rss text/javascript;
#gzip_vary on;
server_name_in_redirect off;
#設定負載均衡的服務器列表
