六、Nginx的安裝與部署

1、安裝工具包 wget、vim和gcc

yum install -y wget  
yum install -y vim-enhanced  
yum install -y make cmake gcc gcc-c++  

2、下載nginx安裝包

wget http://nginx.org/download/nginx-1.6.2.tar.gz

3、安裝依賴包

yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel

4、解壓nginx-1.6.2.tar.gz

tar -zxvf nginx-1.6.2.tar.gz

5、編譯安裝

./configure --prefix=/usr/local/nginx

make && make install

6、啟動Nginx

/usr/local/nginx/sbin/nginx

 ps -ef  |grep nginx

如果要關閉nginx，我們可以使用如下命令：

# /usr/local/nginx/sbin/nginx -s stop

如果想要重新熱啟動nginx

 # /usr/local/nginx/sbin/nginx -s reload

新增Nginx 到 service 啟動

cd /etc/init.d/

vi  nginx

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: 2345 30 30

#              It has a lot of features, but it's not for everyone.

   echo "nginx already running...."
   exit 1

   echo -n $"Starting $prog: "

   echo

   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/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

        exit 1
esac
exit $RETVAL

　
chmod 755 /etc/init.d/nginx 
chkconfig --add nginx 

nginx啟動、停止、無間斷服務重啟 
　　# service nginx start 
　　# service nginx stop 
　  # service nginx reload
