检查nginx的配置

[root@localhost ~]# /usr/local/nginx/sbin/nginx -t -c /usr/nginx/conf/nginx.conf

四、启动测试

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
/usr/local/tomcats/tomcat-a/bin/startup.sh
/usr/local/tomcats/tomcat-b/bin/startup.sh
/usr/local/tomcats/tomcat-c/bin/startup.sh

停止服务

/usr/local/tomcats/tomcat-a/bin/shutdown.sh
/usr/local/tomcats/tomcat-b/bin/shutdown.sh
/usr/local/tomcats/tomcat-c/bin/shutdown.sh
pkill -9 nginx

重启服务

/usr/local/nginx/sbin/nginx -s reload
