今天在安装完成hhvm以后出现了没法访问的情况，老出现NGINX的502 bad getway，后来发现是hhvm没有启动起来。
HHVM 权限设置：
查日志发现如下错误：
[crit] 2332#0: *681 connect() to unix:/tmp/hhvm.sock failed (13: Permission denied) while connecting to upstream, client: 104.224.169.175, server: b.jiloc.com, request: “GET /p.php HTTP/1.1”, upstream: “fastcgi://unix:/tmp/hhvm.sock:”, host: “b.jiloc.com”
Permission denied 表示权限不足，我们把socket文件设置在了 /tmp 文件夹下。如果我们手动设置成777权限就可以运行了。
我们的HHVM 版本是 3.2的，网上的一些方法好像已经不能用了。
现在我们通过修改配置文件方式进行修改。
vi /etc/hhvm/server.hdf
文件内容如下：
PidFile = /var/run/hhvm.pid
Server {
#Port = 9000
# SourceRoot = /var/www/
Type=fastcgi ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?# 我们这里是配合nginx，作为fastcgi启动
FileSocket = /tmp/hhvm.sock ? ? ? ? ? ?# 在这里设置socket方式，这里说一下这个值要跟nginx里的php段?fastcgi_pass后面的参数一致
DefaultDocument = index.php
}

HHVM启动脚本修复：
比较奇怪的是，我安装完成以后发现/etc/init.d/hhvm 脚本出了问题，原先连正常启动都不行，我们修改后可以启动start跟停止stop了，下面贴一下代码：
cat /etc/init.d/hhvm
代码如下：
#!/bin/bash
#
# /etc/rc.d/init.d/hhvm
#
# Starts the hhvm daemon
#
# chkconfig: 345 26 74

stop() {
echo -n “Shutting down hhvm: ”
#killproc `cat /var/run/hhvm.pid`
ps -ef | grep -e hhvm | grep -v grep | awk ‘{print $2}’ | xargs -i kill -9 {}
rm -f /var/lock/subsys/hhvm
}
