在安装完nginx后,重新启动需要“kill -HUP nginx进程编号”来进行重新加载,显然十分不方便。如果能像apache一样,直接通过脚本进行管理就方便多了。nginx官方早就想好了,也提供了这个脚本,地址:http://wiki.nginx.org/RedHatNginxInitScript。这里将管理脚本收录在这里:
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# 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"] && exit0
  
nginx="/usr/sbin/nginx"
prog=$(basename$nginx)
  
NGINX_C/etc/nginx/nginx.conf"
  
[ -f /etc/sysconfig/nginx] && . /etc/sysconfig/nginx
  
lockfile=/var/lock/subsys/nginx
  
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep"configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if[ -z "`grep $user /etc/passwd`"]; then
       useradd-M -s /bin/nologin$user
   fi
   opti -V 2>&1 | grep'configure arguments:'`
   foropt 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 ] || exit5
    [ -f $NGINX_CONF_FILE ] || exit6
    make_dirs
    echo-n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq0 ] && touch$lockfile
    return$retval
}
  
stop() {
    echo-n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq0 ] && rm-f $lockfile
    return$retval
}
  
restart() {
    configtest || return$?
    stop
    sleep1
    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/null2>&1
}
  
case"$1" in
    start)
        rh_status_q && exit0
        $1
        ;;
    stop)
        rh_status_q || exit0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit0
            ;;
    *)
        echo$"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit2
esac

将以上脚本保存到/etc/init.d/nginx文件,并修改两个地方:
  • nginx=”/usr/sbin/nginx” 修改成nginx执行程序的路径。
  • NGINX_C/etc/nginx/nginx.conf” 修改成配置文件的路径。
  • 保存后,就可以通过该脚本对nginx服务进行管理了:$ /etc/init.d/nginx start $ /etc/init.d/nginx stop $ /etc/init.d/nginx reload ...使用chkconfig进行管理上面的方法完成了用脚本管理nginx服务的功能,但是还是不太方便,比如要设置nginx开机启动等。这时可以使用chkconfig来设置。先将nginx服务加入chkconfig管理列表:chkconfig --add /etc/init.d/nginx加完这个之后,就可以使用service对nginx进行启动,重启等操作了。$ service nginx start $ service nginx stop $ service nginx reload ...设置终端模式开机启动:$ chkconfig --level 3 nginx on

    以上就介绍了centos下nginx启动脚本和chkconfig管理,包括了方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
