我正在尝试由无业游民自动安装的/vagrant进行nginx负载配置。
所以我编辑了nginx.service以使其在挂载共享文件夹后启动，但它不起作用。
当然，nginx已在virtualbox-guest-utils.service之后启动，但是似乎在vagrant.mount（/ vagrant）之前启动了。因为nginx无法从/ vagrant加载配置，并且在手动运行命令systemctl restart nginx.service后可以正常工作。
自动生成的.mount单元启动后如何运行.service单元？
# /lib/systemd/system/nginx.service

# ExecStop sends SIGSTOP (graceful stop) to the nginx process.
# If, after 5s (--retry QUIT/5) nginx is still running, systemd takes control
# and sends SIGTERM (fast shutdown) to the main process.
# After another 5s (TimeoutStopSec=5), and if nginx is alive, systemd sends
# SIGKILL to all the remaining processes in the process group (KillMode=mixed).

我写了post how I'm using udev event to restart nginx and php5-fpm。
简而言之，我将udev与规则相加：
/etc/udev/rules.d/50-vagrant-mount.rules脚本SUBSYSTEM=="bdi",ACTION=="add",RUN+="/bin/bash /root/.udev-mount-restart-services.sh"
是：
/root/.udev-mount-restart-services.sh使用mount.target单位似乎起作用。
Vagrantfile：
sleep 5 # wait for a bit for NFS to make sure resources are available
systemctl restart php5-fpm > /dev/null 2>&1
systemctl restart nginx > /dev/null 2>&1
bootstrap.sh：
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/wily64"
config.vm.provision :shell, path: "bootstrap.sh"
# Disabling mounting of the /vagrant directory to make sure ngnix is blocked
# Comment this out to allow the shared folder
config.vm.synced_folder ".", "/vagrant", disabled: true
end
通过运行#!/usr/bin/env bash
apt-get update
apt-get install -y nginx
# Make vagrant.mount loosely dependent on nginx.service
sed -i 's/WantedBy=multi-user.target/WantedBy=vagrant.mount/' /lib/systemd/system/nginx.service
systemctl daemon-reload
# Update service symlinks
systemctl disable nginx.service
systemctl enable nginx.service
进行测试，以使VM在未安装/ vagrant目录的情况下启动。登录到虚拟机，然后查看nginx没有运行：
vagrant reload然后注释掉禁用共享文件夹的Vagrantfile行和再次单击vagrant@vagrant-ubuntu-wily-64:~$ sudo systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
Active: inactive (dead)
。再次登录到VM，然后查看nginx是否正在运行：
vagrant reload编辑vagrant@vagrant-ubuntu-wily-64:~$ systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

并在/lib/systemd/system/nginx.service部分下更改WantedBy指令...
Install您可以通过以下方式检查WantedBy=vagrant.mount
事件是否存在：vagrant.mount。您应该看到以下内容：
systemctl list-units vagrant.mount根据Ansible总结先前的答案和评论（如果用于提供）：
UNIT LOAD ACTIVE SUB DESCRIPTION
vagrant.mount loaded active mounted /vagrant
LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
用流浪汉安装单元名称替换- name: Copy Nginx Systemd unit to /etc/
copy:
src: /lib/systemd/system/nginx.service
dest: /etc/systemd/system/nginx.service
remote_src: yes
- name: Change Nginx Systemd unit
lineinfile:
path: /etc/systemd/system/nginx.service
regexp: '^WantedBy='
line: 'WantedBy={{ vagrant_mount_unit }}'
state: present
- name: Systemd daemon reload
systemd:
daemon_reload: yes
- name: Disable Nginx
service:
name: nginx
enabled: no
- name: Enable Nginx
service:
name: nginx
enabled: yes
。它取决于安装点，例如如果安装点为{{ vagrant_mount_unit }}，则单元名称为/home/vagrant/app。
我想在这里放下自己的答案，因为似乎每个答案都包含正确答案的一部分，并且某些详细信息只能在注释中找到。
在此示例中，我在/ var / www / mymount1和/ var / www / mymount2中有2个文件系统挂载
我的Vagrantfile的这一部分：
home-vagrant-app.mount我将下面的脚本作为我的供应商文件放在/docs/vagrant/init-vagrant.sh中。
config.vm.provision "shell", path: "docs/vagrant/init-vagrant.sh"
config.vm.synced_folder "mymount1", "/var/www/mymount1", type: "nfs"
config.vm.synced_folder "mymount2", "/var/www/mymount2", type: "nfs"
