本文介绍如何安装Nginx 1.4.7版本并进行基本配置，包括设置启动脚本，调整文件权限，将Nginx添加为系统服务，以及如何使用命令行工具启动、停止和重启Nginx服务。

1、安装命令

wget http://nginx.org/download/nginx-1.4.7.tar.gz
tar zxvf nginx-1.4.7.tar.gz
cd nginx-1.4.7
./configure --prefix=/usr/local/webserver/nginx
make && make install

2、启动脚本配置

#配置nginx在任意目录都可以执行nginx的启动、停止、重启的脚本
#执行以下命令，书写脚本
vi /etc/init.d/nginx

写入如下脚本：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/webserver/nginx/conf/nginx.conf
# pidfile:     /usr/local/webserver/nginx/logs/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/local/webserver/nginx/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/usr/local/webserver/nginx/conf/nginx.conf"

lockfile=/var/lock/subsys/nginx

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    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
    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
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

3、修改权限

chmod +x /etc/init.d/nginx

4、添加到系统服务

 /sbin/chkconfig nginx on

5、如下命令操作nginx

 service nginx start
    service nginx stop
    service nginx restart
    service nginx reload

    /etc/init.d/nginx start
    /etc/init.d/nginx stop
    /etc/init.d/nginx restart
    /etc/init.d/nginx reload
