1、错误原因是没有添加nginx服务，所以启动失败
解决办法
1、在etc/init.d/目录下创建文件，文件名叫nginx，内容为：
#!/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/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
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart|configtest)
$1
;;

rh_status_q || exit 7
$1

force-reload)
force_reload
;;

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
注：nginx安装目录为/usr/local/nginx，目录不对的需要修改以上代码内的nginx路径
2、
cd /etc/init.d
chmod 755 /etc/init.d/nginx
chkconfig --add nginx文章来源：https://www.toymoban.com/news/detail-799969.html
3、开启nginx
开启之前先kill掉之前的nginx服务
systemctl start nginx文章来源地址https://www.toymoban.com/news/detail-799969.html
