WordPressを動かすためにPHPやApatch、データベースソフトのMySql、環境移行のときに用い得るruby環境下で動くwordmoveなどの各種ツールのインストールや設定を自動化しているのが、VCCWである。 その開発のための仮想環境を構築するVirtualBoxとvagrantをインストールし、WordPressを起動しようとした際に以下のエラーが起こった。 もろもろのインストールや環境設定の変更後、最後に
vagrant up
のコマンドを実行したところ、

というエラーが発生し、WordPressの初期画面を開くことが出来なかった。 エラーにはno implicit conversion of nil into String (TypeError)とあったので、どこかのファイルに問題があるのかと思い確認したが、結果的にはvagrantの起動時に仮想環境のIPアドレスを自動設定する際にエラーが発生していた。 vccwのファイル「Vagrantfile」に、hostmanagerの設定を以下のように追記していたものを修正することで解決。 （初期）
config.vm.hostname = _conf['hostname'] config.vm.network :private_network, ip: _conf['ip'] config.vm.synced_folder ".", "/vagrant", :mount_options => ['dmode=755', 'fmode=644'] config.vm.synced_folder _conf['sync_folder'], _conf['document_root'], :create => "true", :mount_options => ['dmode=755', 'fmode=644']
↓ （誤）
config.vm.hostname = _conf['hostname']
config.vm.network :public_network, type: 'dhcp', bridge: 'en1: Wi-Fi (AirPort)'
config.hostmanager.enabled = true
config.hostmanager.manage_host = true
config.hostmanager.ip_resolver = proc do |vm, resolving_vm|
ip_address = ''
if hostname = (vm.ssh_info && vm.ssh_info[:host])
vm.communicate.execute("/sbin/ifconfig enp0s8 | grep 'inet addr' | tail -n 1 | egrep -o '[0-9\.]+' | head -n 1 2>&1") do |type, contents|
ip_address = contents.split("\n").first
end
end
ip_address
end
config.vm.synced_folder ".", "/vagrant", :mount_options => ['dmode=755', 'fmode=644']
config.vm.synced_folder _conf['sync_folder'], _conf['document_root'], :create => "true", :mount_options => ['dmode=755', 'fmode=644']
↓ （正）
config.vm.hostname = _conf['hostname']
config.vm.network :public_network, type: 'dhcp', bridge: 'en1: Wi-Fi (AirPort)'
config.hostmanager.enabled = true
config.hostmanager.manage_host = true
config.hostmanager.ip_resolver = proc do |vm, resolving_vm|
ip_address = ''
if hostname = (vm.ssh_info && vm.ssh_info[:host])
vm.communicate.execute("/sbin/ifconfig enp0s8 | grep 'inet addr' | tail -n 1 | egrep -o '[0-9\.]+' | head -n 1 2>&1") do |type, contents|
ip_address = contents.split("\n").first
end
end
ip_address
end
具体的に修正では
config.vm.synced_folder ".", "/vagrant", :mount_options => ['dmode=755', 'fmode=644'] config.vm.synced_folder _conf['sync_folder'], _conf['document_root'], :create => "true", :mount_options => ['dmode=755', 'fmode=644']
の部分を削除したのだが、この部分はNFSを使ってファイルアクセスを速くするための記述である。基本的にコメントアウトする所を変更するだけであるため、本来であれば再起動することにより、速さを実感できるようである。そのため、今回のエラーも再起動することにより、何かしらの改善が見られたかもしれません。。。（実行済みではないため、真偽不明です）
