ui失败

服务器意外断电后使用命令“zstack-ctl start_ui”报错：

请先在命令行输入 ：ps aux | grep pm2。 如果发现有许多的pm2进程，就ps aux | grep pm2 |xargs kill -9 杀掉他们。

[admin-ping]

查找并未发现存在pm2进程

[sinbargit]

ps aux | grep node 会出现很多进程么

[admin-ping]

这是具体返回结果 [root@192-168-1-70 ~]# ps aux | grep pm2 root 26945 0.0 0.0 112708 976 pts/2 S+ 14:41 0:00 grep --color=auto pm2

[sinbargit]

如果ps aux | grep node 有进程，就杀掉他们。 不管有没有都可以尝试运行下systemctl start pm2-zstack

运行这个 /usr/local/zstack/zstack-ui/node_modules/pm2/bin/pm2 resurrect

那么 这个看起来并不是断电造成的，似乎是底层库没有兼容，或者说node本身的问题。 你可以尝试直接运行 node 看看是否工作，如果不工作，重新安装node就可以。

[admin-ping]

运行node提示： [root@192-168-1-70 ~]# node node: relocation error: node: symbol -Emcmp, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference

断电前是正常运行的，断电重启后就出现错误，具体原因还未知

zstack-ctl里未发现install node，请问该如何安装

[sinbargit]

这个只要是14.15.1版本或者以上的nodejs都可以的。 可以使用yum install 安装，也可以网上下载安装包安装，或者自己编译构建安装都可以。

整合解决方案：

运行一下命令 yum -y remove nodejs yum -y install nodejs zstack-ctl stop zstack-ctl start 成功解决
