sudo systemctl start nginx => Failed to start nginx.service: Unit not found.
原因就是没有添加nginx服务,所以启动失败。
解决方法:
1. 在/root/etc/init.d/目录下新建文件名为nginx及命令行执行 touch nginx
或者用命令在根目录下执行:# vim /etc/init.d/nginx (注意vim旁边有一个空格)
2. 插入以下代码
#!/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 ;; 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. 用命令进入此目录
# cd /etc/init.d
4. 依此执行以下命令
# chmod 755 /etc/init.d/nginx
# chkconfig --add nginx (注意add前面是两个短横线-)
5. 开启nginx
# service nginx start
补充:Centos nginx重启
service nginx restart /etc/init.d/nginx stop /etc/init.d/nginx start $sudo service nginx start $sudo service nginx stop
