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
