[colintheunique]

你正在使用哪个版本的 V2Ray？

你的使用场景是什么？

正常翻墙

你看到的异常现象是什么？

安装完后端口还是TCP不可用，国内外均不可用
安装过程中，出现fastmirror链接超时，启用cache 镜像：

vps的防火墙配置了没有？除了22端口，其他端口vps默认不开放的。
233boy的脚本说明里有写：
使用国际大厂的 VPS，请自行在安全组 (防火墙) 开放端口和 UDP 协议 (如果你要使用含有 mKCP 的传输协议)

解决了打开端口问题，为什么我现在安装V2RAY之后，查看状态还是未运行呢？
5.1和之前版本都试过了

[root@vultr ~]# v2ray status

[root@vultr ~]# v2ray start

V2Ray 已启动

这是安装V2ray的问题造成的吗？

跟安装时的mirror有关系吗？

systemctl status v2ray

用systemctl status v2ray -l看看完整日志，另外你IP暴露了

你的防火墙激活了么？我看到你的结果public后面没有(active)字样。

应该是激活了的，我也不知奥为啥没有active

firewall-cmd --state;查是active的状态

[azzvx]

firewall-cmd --get-active-zones的结果呢？

[colintheunique]

firewall-cmd --get-active-zones

[root@vultr ~]# firewall-cmd --get-active-zones
[root@vultr ~]#

无返回

[azzvx]

你的防火墙没有应用到接口。应用到接口后看看结果。

firewall-cmd --permanent --zone=public --add-interface=eth0
firewall-cmd --reload
firewall-cmd --list-all

[azzvx]

或者换个版本看看。
