记录一次v2ray安装过程

主要是这类错误，如果出现这条，即表明CAPABILITIES这个有问题ExecStart=/usr/local/bin/v2ray -config /usr/local/etc/v2ray/config.json (code=exited, status=218/CAPABILITIES)


文件在/etc/systemd/system/v2ray.service，删掉CapabilityBoundingSet=CAP_NET_ADMIN CAP_NET_BIND_SERVICE
AmbientCapabilities=CAP_NET_ADMIN CAP_NET_BIND_SERVICE
如果修改了User=nobody 还会出现user错误(code=exited, status=217/USER)

出现Could not resolve host: raw.githubusercontent.com; Unknown error这类解析错误，需要增加DNS服务，
/etc/resolv.conf被清空的原因是/etc/sysconfig/network-scripts/ifcfg-eth0中没有dns server信息，所以重启后系统自动使用/etc/sysconfig/network-scripts/ifcfg-eth0中的设置重新设置/etc/resolv.conf，导致修改/etc/resolv.conf无效。只要将/etc/sysconfig/network-scripts/ifcfg-eth0中加入nameserver信息， /etc/resolv.conf根本不用做修改，系统重启或网络重启后会自动根据ifcfg-eth0设置resolv.conf。
知道了原因，彻底解决的方法就有了：打开ifcfg-eth0，在末尾加上下面语句：下面xxx用dns server的地址代替。
DNS1=8.8.8.8
DNS2=8.8.4.4
重启网络服务：service network restart

删掉后运行命令1重新载入、systemctl daemon-reload
2重启v2、service v2ray restart
3查看运行状态、service v2ray status
安装BT，安装Nginx
一键去除注册命令sed -i "s|if (bind_user == 'True') {|if (bind_user == 'REMOVED') {|g" /www/server/panel/BTPanel/static/js/index.js
新建网站，申请SSL，放行23450端口
修改配置文件 location /目录 {
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_intercept_errors on;
if ($http_upgrade = "websocket" ){
proxy_pass http://127.0.0.1:23450; #自定义端口，与下同
}
}
修改/usr/local/etc/v2ray/config.json
