环境：
centos7、nginx 1.10.1
在以上都已经安装完成，能正常启动之后
配置服务：
centos7 的服务管理 与 centos6 发生了一些变化 ，此处参考
启动、停止、重启、重载、检查服务：
6: service httpd start|stop|restart|reload|status 7: systemctl start|stop|restart|reload|status httpd.service允许、禁止服务自启动：
6: chkconfig httpd on|off 7: system enable|disable httpd.service列出服务：
6: chkconfig –list 7: systemctl list-unit-files –type=service 或 ls /etc/systemd/system/*.wants/添加服务：
6: chkconfig httpd –add 7: systemctl daemon-reload
可以先通过上述命令查询是否已经配置nginx服务，如果没有
centos7：
服务文件
#systemd 下的 system 或 usr 创建 nginx.service 文件vim /usr/lib/systemd/system/nginx.service #nginx服务配置到该文件中#服务描述性的配置[Unit]Description=nginx - high performance web serverDocumentation=http://nginx.org/en/docs/After=network.target remote-fs.target nss-lookup.target#服务关键配置[Service]Type=forking#pid文件位置 #要与nginx配置文件中的pid配置路径一致，这个很重要，否则会服务启动失败PIDFile=/var/run/nginx.pid#启动前检测 nginx配置文件 是否正确ExecStartPre=/usr/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf#启动ExecStart=/usr/sbin/nginx -c /usr/local/nginx/conf/nginx.conf#重启ExecReload=/bin/kill -s HUP $MAINPID#关闭ExecStop=/bin/kill -s QUIT $MAINPIDPrivateTmp=true[Install]WantedBy=multi-user.target
启动服务
systemctl start nginx.service
设置开机自启
systemctl enable nginx.service
centos6:
在 /etc/init.d 中新增 nginx 文件，内容如下
#!/bin/bash# nginx Startup script for the Nginx HTTP Server# it is v.0.0.2 version.# chkconfig: - 85 15# description: Nginx is a high-performance web and proxy server.# It has a lot of features, but it's not for everyone.# processname: nginx# pidfile: /var/run/nginx.pid# config: /usr/local/nginx/conf/nginx.confnginxd=/usr/local/nginx/sbin/nginxnginx_config=/usr/local/nginx/conf/nginx.confnginx_pid=/var/run/nginx.pidRETVAL=0prog="nginx"# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ ${NETWORKING} = "no" ] && exit 0[ -x $nginxd ] || exit 0# Start nginx daemons functions.start() {if [ -e $nginx_pid ];then echo "nginx already running...." exit 1fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL}# Stop nginx daemons functions.stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid}# reload nginx service functions.reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo}# See how we were called.case "$1" instart) start ;;stop) stop ;;reload) reload ;;restart) stop start ;;status) status $prog RETVAL=$? ;;*) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1esacexit $RETVAL 然后设置自启
#添加服务chkconfig --add nginxchkconfig nginx on
启动服务
service nginx start
