cenos 安装nginx并添加到service

 

系统平台：CentOS release 6.6 (Final) 64位。

一、安装编译工具及库文件

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 Ngnix 支持 Rewrite 功能。

1、下载 PCRE 安装包，下载地址： http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解压安装包:

[root@bogon src]# tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

[root@bogon src]# cd pcre-8.35

4、编译安装 

[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install

5、查看pcre版本

[root@bogon pcre-8.35]# pcre-config --version

安装 Nginx

1、下载 Nginx，下载地址：http://nginx.org/download/nginx-1.6.2.tar.gz

[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

2、解压安装包

[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz

3、进入安装包目录

[root@bogon src]# cd nginx-1.6.2

4、编译安装

[root@bogon 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-8.35
[root@bogon nginx-1.6.2]# make
[root@bogon nginx-1.6.2]# make install

5、查看nginx版本

[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

到此，nginx安装完成。

Nginx 配置

创建 Nginx 运行使用的用户 www：

[root@bogon conf]# /usr/sbin/groupadd www 
[root@bogon conf]# /usr/sbin/useradd -g www www

配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容

 

[root@bogon conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf

user 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;
  }

}

检查配置文件ngnix.conf的正确性命令：

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

---

启动 Nginx

Nginx 启动命令如下：

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx

---

访问站点

从浏览器访问我们配置的站点ip：

---

Nginx 其他命令

以下包含了 Nginx 常用的几个命令：

/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

 三：将nginx添加到系统service

1. vim /etc/init.d/nginx       将下面的代码复制进去保存

#!/bin/bash  
# nginx Startup script for the Nginx HTTP Server  
#  
# 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=/usr/local/nginx/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: " 
 $nginxd -s reload  
    #if your nginx version is below 0.8, please use this command: "kill -HUP `cat ${nginx_pid}`" 
    RETVAL=$?  
    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 

3. 保存文件后执行以下代码：

 [root@localhost /]# cd /etc/rc.d/init.d

[root@localhost init.d]#  chmod +x nginx

 [root@localhost init.d]# /sbin/chkconfig --level 345 nginx on

任何位置都能运行   service nginx start           可选  start | stop | restart | reload | status |  help
