Nginx安装

一、安装所需的库及插件

1.pcre （重写功能需用到此库）

[root@localhost ~]# yum install pcre pcre-devel

2.open-ssl  （https需要用到，没装此插件会报错）

[root@localhost ~]# yum install openssl-devel

3.安装编译功能

yum -y install gcc gcc-c++ autoconf automake make

二、安装Nginx

1.创建存放目录

mkdir -p /home/minki/tools

2.下载安装包

wget -q http://nginx.org/download/nginx-1.6.3.tar.gz

3.创建nginx用户

[root@localhost tools]# useradd nginx -s /sbin/nologin -M

4.解压nginx安装包

[root@localhost tools]# tar -zxvf nginx-1.6.3.tar.gz

5.编译安装nginx

 [root@localhost nginx-1.6.3]#./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.3/ --with-http_stub_status_module --with-http_ssl_module

 解释： --prefix=/application/nginx-1.6.3/ （安装目录） --user=nginx --group=nginx（进程用户和组权限）  --with-http_ssl_module（启用ssl功能）

[root@localhost nginx-1.6.3]#make&&make install

[root@localhost nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx     ####将安装目录软链接到/application/nginx

，方便人员使用

6.启动前检查配置文件语法

[root@localhost nginx-1.6.3]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful

7.启动nginx

[root@localhost nginx-1.6.3]# /application/nginx/sbin/nginx

8.检查对应端口是否启动成功

[root@localhost nginx-1.6.3]# lsof -i:80

COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   8705  root    6u  IPv4  64849      0t0  TCP *:http (LISTEN)
nginx   8706 nginx    6u  IPv4  64849      0t0  TCP *:http (LISTEN)

9.访问http://192.168.26.133或者 curl 127.0.0.1

10.查看进程

[root@localhost nginx-1.6.3]# ps -ef|grep nginx

root      8705     1  0 21:07 ?        00:00:00 nginx: master process /application/nginx/sbin/nginx
nginx     8706  8705  0 21:07 ?        00:00:00 nginx: worker process        
root      8748  6065  0 21:15 pts/0    00:00:00 grep nginx

11.设置开机启动

一、在/etc/init.d/中添加nginx文件，并在nginx配置文件中添加如下参数：

#!/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

##########如下参数根据自己安装路径设置
nginxd=/application/nginx/sbin/nginx
nginx_config=/application/nginx/conf/nginx.conf
nginx_pid=/application/nginx/logs/nginx.pid

###################################
RETVAL=0
prog="nginx"
# Source function library.

# Source networking configuration.

# 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 /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

case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;

        status $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

二、设置权限

chmod a+x /etc/init.d/nginx (a+x参数表示 ==> all user can execute  所有用户可执行)

三、在/etc/rc.local中添加nginx启动参数

加入 /etc/init.d/nginx start
