在运行Ubuntu的Homestead vagrant盒子上执行PHP命令时,我一直在挂起.在控制台甚至启动php cli执行之前有一个显着的延迟.
strace -vyT -S time php artisan help从流浪者的盒子里跑出来.在第一次到最后一次通话时recvfrom(3,所有东西都会卡住几分钟,但我不明白为什么:

这是以下内容/etc/hosts:
127.0.0.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
127.0.1.1 homestead homestead
内容/etc/resolve.conf:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 10.0.2.3
问题是现在影响我所拥有的每个无关的流浪者盒子,而不仅仅是Homestead盒子.对于每个CLI执行,几乎每个盒子上的每个PHP命令都会停止5-15分钟.如果必须调用一系列命令,则可能需要一个小时才能完成一个需要30秒的过程.
在Mac运行后,这些盒子运行升级为El Capitan.
根据流浪者的盒子,有时这个strace线:
connect(3, {sa_family=AF_INET, sin_port=htons(9000), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
替换为:
connect(3, {sa_family=AF_INET, sin_port=htons(9000), sin_addr=inet_addr("192.168.56.1")}, 16) = 0
IP 192.168.56.1似乎是VirtualBox的默认路由器.
请注意,所有流浪盒都是标准配置或在我的其他团队成员的Mac/Windows系统上没有问题的那些.
Vagrant 1.7.4和VirtualBox 4.3.30.
响应请求route -n:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.0.2.2 0.0.0.0 UG 0 0 0 eth0
10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
结果sudo netstat -tulnp | grep 9000:
tcp6 0 0 :::9000 :::* LISTEN 1317/hhvm
为什么hhvm出现,我不知道,因为该框应该使用标准的PHP解释器.
tl;dr：我责怪 xdebug 客户端。尝试在 Ubuntu 上禁用 xdebug。
我的理由：
我在 strace 日志中没有看到任何主机解析问题。
它/etc/resolv.conf首先检查，然后/etc/hosts连接到 127.0.0.1:9000connect(3, {sa_family=AF_INET, sin_port=htons(9000), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EINPROGRESS (Operation now in progress) <0.000094>
端口 9000 是 xdebug 的默认端口，除非在/etc/php5/mods-available/xdebug.ini或类似中重新定义。
write(3<socket:[78362]>, "478\0<?xml version=\"1.0\" encoding"..., 483) = 483 <0.000042>看起来像是从 xdebug 扩展发送到客户端的消息。
它等待 2 分钟recvfrom(3, 0x7ffc489b16d0, 128, 0, 0, 0) = ? ERESTARTSYS，然后放弃并执行您的 php 脚本。
自 v2.2.4 以来，等待时间已减少至 200 毫秒： https: //github.com/xdebug/xdebug/pull/90
假设禁用 xdebug 可以解决问题，有几个选项：
xdebug.remote_autostart=off
