概要

その2の続き

Vagrantで構築したCentOS 7上にyumリポジトリ追加したりNginx/MySQL/Redis/PHPをインストールした

今回はインストールした諸々の自動起動設定とかして、一旦イメージとしてexportする

今後拡張していった時にぶっ壊れてもここまでは戻れるセーブポイント的な意味で

復習

インストールしたのはこれら

※ RedisとかPHPとか若干バージョン上がっているのは、yum updateかけたから

[vagrant@localhost ~]$ sudo yum clean all && sudo yum update -y

自動起動の設定確認

CentOS 7ではsystemctlを使う

systemctl list-unit-filesで各serviceの自動起動の設定が確認できる

[vagrant@localhost ~]$ systemctl list-unit-files | grep -i "nginx\|mysql\|redis\|php"
mysqld.service                                enabled
mysqld@.service                               disabled
nginx.service                                 disabled
php-fpm.service                               disabled
redis-sentinel.service                        disabled
redis.service                                 disabled

mysqld.serviceが有効でそれ以外は無効な様子

そもそもmysqld.serviceとmysqld@.serviceの違いはなんだ…

[vagrant@localhost ~]$ systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2018-07-09 11:25:48 UTC; 43min ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
 Main PID: 1549 (mysqld)
   CGroup: /system.slice/mysqld.service
           └─1549 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid
[vagrant@localhost ~]$ systemctl status mysqld@
Failed to get properties: Unit name mysqld@.service is missing the instance name.

mysqldは起動しているが、mysqld@は知らないと言われてしまったので無視する

自動起動の有効化

自動起動有効になっていないNginx/Redis/php-fpmの設定を有効にする

有効にするときはsystemctl enableを使う

※ 無効にするときはsystemctl disable

こんな感じで有効化してあげる

[vagrant@localhost ~]$ sudo systemctl enable nginx redis redis-sentinel php-fpm

以下のようになっていればOK

[vagrant@localhost ~]$ systemctl list-unit-files | grep -i "nginx\|mysql\|redis\|php"
mysqld.service                                enabled
mysqld@.service                               disabled
nginx.service                                 enabled
php-fpm.service                               enabled
redis-sentinel.service                        enabled
redis.service                                 enabled

自動起動するか確認

OS再起動してちゃんと各プロセスが自動起動するか確認する

まず停止しておく

[vagrant@localhost ~]$ sudo systemctl stop nginx mysqld redis redis-sentinel php-fpm | grep Active
[vagrant@localhost ~]$ systemctl status nginx mysqld redis redis-sentinel php-fpm | grep Active
   Active: inactive (dead) since Mon 2018-07-09 13:50:58 UTC; 5s ago

   Active: inactive (dead) since Mon 2018-07-09 13:50:58 UTC; 5s ago
   Active: inactive (dead) since Mon 2018-07-09 13:50:58 UTC; 5s ago
[vagrant@localhost ~]$ ps aux | grep -i "nginx\|mysql\|redis\|php"

止まっている

Vagrantなので、logoutしてからvagrant reloadで再起動

[vagrant@localhost ~]$ logout
Connection to 127.0.0.1 closed.
$ vagrant reload
$ vagrant ssh

sshしたらそのまま確認

[vagrant@localhost ~]$ systemctl status nginx mysqld redis redis-sentinel php-fpm | grep Active

無事に諸々動いている模様

イメージとしてExport

今の状態をVagrantのboxイメージとしてファイルにexportする

※ ファイルとかいらないものがあったら消しておくと良いかも

ログアウトする

[vagrant@localhost ~]$ logout
Connection to 127.0.0.1 closed.

vagrant packageコマンドでexportする

$ vagrant package --help
Usage: vagrant package [options] [name|id]

Options:

        --base NAME                  Name of a VM in VirtualBox to package as a base box (VirtualBox Only)
        --output NAME                Name of the file to output
        --include FILE,FILE..        Comma separated additional files to package with the box
        --vagrantfile FILE           Vagrantfile to package with the box
    -h, --help                       Print this help

$ vagrant package --output sample.box
==> default: Attempting graceful shutdown of VM...
==> default: Clearing any previously set forwarded ports...
==> default: Exporting VM...
==> default: Compressing package to: hogehoge/sample.box
$ ll
total 1179556
-rw-r--r-- 1 hoge 197609 1207860212 7月   9 22:00 sample.box
-rw-r--r-- 1 hoge 197609       3085 6月   4 19:39 Vagrantfile

こんな感じで出来上がる

Exportしたイメージを使う

流れとしては↓

作成したイメージファイルをvagrant box addする
vagrant initでaddしたイメージを指定する
vagrant upする

現在ローカルマシンに登録されているイメージを確認

$ vagrant box list
centos/7 (virtualbox, 1804.02)

その1でCentOS 7のイメージを使ったから、そいつが登録されている

先ほど作成したsample.boxを登録してやる

$ vagrant box add --help
Usage: vagrant box add [options] <name, url, or path>

Options:

    -c, --clean                      Clean any temporary download files
    -f, --force                      Overwrite an existing box if it exists
        --insecure                   Do not validate SSL certificates
        --cacert FILE                CA certificate for SSL download
        --capath DIR                 CA certificate directory for SSL download
        --cert FILE                  A client SSL cert, if needed
        --location-trusted           Trust 'Location' header from HTTP redirects and use the same credentials for subsequent urls as for the initial one
        --provider PROVIDER          Provider the box should satisfy
        --box-version VERSION        Constrain version of the added box

The box descriptor can be the name of a box on HashiCorp's Vagrant Cloud,
or a URL, or a local .box file, or a local .json file containing
the catalog metadata.

The options below only apply if you're adding a box file directly,
and not using a Vagrant server or a box structured like 'user/box':

        --checksum CHECKSUM          Checksum for the box
        --checksum-type TYPE         Checksum type (md5, sha1, sha256)
        --name BOX                   Name of the box
    -h, --help                       Print this help

$ vagrant box add --name sample sample.box
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'sample' (v0) for provider:
    box: Unpacking necessary files from: file://hogehoge/sample.box
    box:
==> box: Successfully added box 'sample' (v0) for 'virtualbox'!
$ vagrant box list
centos/7 (virtualbox, 1804.02)
sample   (virtualbox, 0)

これでsampleという名前で自作イメージが使えるようになったので、このイメージからVMを起動してみる

今まで使っていたCentOS 7ベースのものとは別で立ち上げる

$ vagrant status
Current machine states:

default                   poweroff (virtualbox)

The VM is powered off. To restart the VM, simply run `vagrant up`

vagrant packageした時に停止されたままなのでこのまま放っておき、別ディレクトリで作業する

※ これはこのままvagrant upすればまた動くので、以降うまくいかなかったらここからやり直せばOK

$ cd {適当なディレクトリ}
$ vagrant init sample
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

いざ

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'sample'...
==> default: Matching MAC address for NAT networking...
...
Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant

The error output from the command was:

mount: unknown filesystem type 'vboxsf'

失敗した…そんなに変なもの入れたりしてないけどなー

ホストとゲストでバージョン不一致があると起こる？という情報があった

最後に

Windows10(64bit)にVagrant+VirtualBoxで開発環境作るのは一旦ここまで

このあとやっていきたいことは↓

Laravelを使ってPHPのWebアプリを作る
ChefやAnsibleを使ってInfra as Codeを進める
Dockerで環境構築する

などなど
