linux部署项目，日志显示发布成功却无法访问的问题

### **1.排查是否主程序是否运行成功，** ###

可以telnet一下tomact的ip+端口，如果telnet成功就说明成功运行，获取tomcat端口的方法

1.首先通过命令：ps -ef|grep tomcat 获得进程号

2.再通过netstat -nlp|grep （进程号）获取端口号

### **2.排除是否代理转发的问题** ###

（排除Nginx是否挂掉了Nginx是否代理成功）

打开Nginx目录下的conf查看nginx.conf

查看转发端口以及转发ip是否有误

无误排查是否是nginx挂掉了，telnet nginx的端口

和上面的一样ps -ef | grep nginx查看进程号查看进程，查看目录路径

netstat -nlp|grep （进程号）获取端口号去telnet

### **3.排除防火墙的问题** ###

查看服务器防火墙是否封禁了对外的端口ip，确定对外开放接口：比如80还是443什么的（是否统一打包对外开放）

查看防火墙firewall-cmd --list-all

看白名单内有没有对外发布的ip以及端口

没有的话就通过firewall-cmd --permanent --add-rich-rule='rule family=“ipv4” source address=“192.168.31.0/24” port protocol=“tcp” port=“80” accept’添加，确定success以后 firewall-cmd --reload重启

# firewall-cmd --list-all

    [root@lixiao-app-22-184 bin]# firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.31.0/24" port protocol="tcp" port="80" accept'
    success
    [root@lixiao-app-22-184 bin]# firewall-cmd reload
    usage: see firewall-cmd man page
    firewall-cmd: error: unrecognized arguments: reload
    [root@lixiao-app-22-184 bin]# firewall-cmd -reload
    usage: see firewall-cmd man page
    firewall-cmd: error: unrecognized arguments: -reload
    [root@lixiao-app-22-184 bin]# firewall-cmd --reload

### **4.排除安全策略的问题（是否安全部封掉了）** ###
