Nginx 启动、重启、停止脚本
 
第一步
先运行命令关闭nginx
sudo kill `cat /usr/local/nginx/logs/nginx.pid`
 
第二步
vi /etc/init.d/nginx
输入以下内容 :
 
#!/bin/bash
#
# 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: /usr/local/nginx/conf/nginx.conf
# pidfile: /usr/local/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/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/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
    start
    ;;
 
    stop)
    rh_status_q || exit 0
    stop
    ;;
    restart|configtest)
    restart
    ;;
    reload)
    rh_status_q || exit 7
    reload
    ;;
    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
 
保存退出
 
第三步
chmod +x /etc/init.d/nginx
 
第四步
/sbin/chkconfig nginx on
检查一下
sudo /sbin/chkconfig --list nginx
nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off
 
完成!
之后,就可以使用以下命令了
service nginx start
service nginx stop
service nginx restart
service nginx reload
service nginx status
 
/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart
/etc/init.d/nginx reload
/etc/init.d/nginx status
