配置Nginx服务

一，安装之前准备
1、nginx依赖: gcc openssl-devel pcre-devel zlib-devel
    安装依赖：yum install gcc openssl-devel pcre-devel zlib-devel
2、创建用户和用户组。为了方便nginx运行而不影响linux安全(不是必须要做的)
    创建组：groupadd -r nginx
    创建用户：useradd -r -g nginx  -M nginx
        　　　-M 表示不创建用户的家目录。

二，安装Nginx

./configure (预编译检查依赖关系)
make && make install

默认安装目录：

/usr/local/nginx

三，配置Nginx为系统服务，以方便管理
  1、在/etc/rc.d/init.d/目录中建立文本文件nginx
  2、在文件中粘贴下面的内容：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   -
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/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 

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

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

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

make_dirs() {
   # make required directories
   user=`nginx -V >& | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   options=`$nginx -V >& | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f `
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}

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

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

restart() {
    configtest || return $?
    stop
    sleep
    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 >&
}

case "$1" in
    start)
        rh_status_q && exit
        $
        ;;
    stop)
        rh_status_q || exit
        $
        ;;
    restart|configtest)
        $
        ;;
    reload)
        rh_status_q || exit
        $
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit
esac

3、修改nginx文件的执行权限

  chmod +x nginx

4、添加该文件到系统服务中去

 chkconfig --add nginx(上面创建的文件)

查看是否添加成功

    chkconfig --list nginx

四，启动，停止，重新装载

service nginx start|stop|reload
