一.安装编译工具及库文件 系统平台：CentOS release 6.6 (Final) 64位。
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二.首先要安装 PCRE PCRE 作用是让 Nginx 支持 Rewrite 功能。 1、下载 PCRE 安装包，下载地址：
wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装
tar zxvf nginx-1.6.2.tar.gzcd nginx-1.6.2 ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35makemake install
3.查看nginx版本
/usr/local/webserver/nginx/sbin/nginx -v
三.Nginx 配置 1.创建 Nginx 运行使用的用户 www
/usr/sbin/groupadd www /usr/sbin/useradd -g www www
2.配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
cat /usr/local/webserver/nginx/conf/nginx.confuser www www;worker_processes 2; #设置值和CPU核心数一致error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别pid /usr/local/webserver/nginx/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.worker_rlimit_nofile 65535;events{ use epoll; worker_connections 65535;}http{ include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; #charset gb2312; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; #limit_zone crawler $binary_remote_addr 10m; #下面是server虚拟主机的配置 server { listen 80;#监听端口 server_name localhost;#域名 index index.html index.htm index.php; root /usr/local/webserver/nginx/html;#站点目录 location ~ .*\.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$ { expires 30d; # access_log off; } location ~ .*\.(js|css)?$ { expires 15d; # access_log off; } access_log off; }} 3.检查配置文件nginx.conf的正确性命令：
/usr/local/webserver/nginx/sbin/nginx -t
4.启动 Nginx
/usr/local/webserver/nginx/sbin/nginx
5.nginx 常用命令
/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx
