CentOS下安装Nginx

一、安装Nginx准备:

1、yum -y install pcre* #将所有的pcre安装包安装上,需连网

2、下载nginx安装包

下载地址:http://nginx.org/en/download.html

二、安装:

1、解压nginx-xxx.tar.gz包

命令:tar -xvf nginx-xxx.tar.gz

2、进入解压包

命令:cd nginx-xxx

3、进行安装

命令:./configure --prefix=/usr/local/nginx-1.9 --with-http_stub_status_module

加入--with-http_stub_status_module是为了后面负载做准备

4、修改配置

命令:vim /usr/local/nginx/conf/nginx.conf,修改servername这里的服务器名称,先修改为自己的IP地址

5、启动

命令:/usr/local/nginx/sbin/nginx

6、将防火墙关闭

        关闭命令:  service iptables stop 
        永久关闭防火墙:chkconfig iptables off

7、验证结果

在浏览器上输入 http://sername 回车,看是否存在welconme nginx页面,是,表示安装成功

三、配置服务

nginx如果每次用脚本启动,比较麻烦,喜欢使用脚本,所以,特意添加nginx添加到service中的脚本,vim /etc/rc.d/init.d/nginx

该配置代码由官网提供,地址:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

#               proxy and IMAP/POP3 proxy server

make_dirs() {
   # make required directories

   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    configtest || return $?
    stop
    sleep 1
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}

force_reload() {
    restart
}

configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;

        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;

        rh_status_q || exit 0
            ;;

        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"

二。将shell脚本放入到 /etc/rc.d/init.d/中,并执行下列命令

1:chmod +x /etc/rc.d/init.d/nginx (设置可执行权限)

2:chkconfig --add nginx (添加系统服务)
