備忘録 Vagrant + VirtualBox + Centos7.2 の環境構築

ローカル環境にCentos7.2サーバーを２つ立ち上げる

• バックエンド用とフロントエンド用のサーバーを別々に立ち上げた時のメモ [サーバー仕様]

設定	バックエンド	フロントエンド	備考
OS	centos7	centos7
hostname	backend	front	設定するとVirtual Boxのマシン名になった気がする
public ip	192.168.0.10	192.168.0.50
private ip	192.168.33.10	192.168.33.50
port(guest)	8080	80
port(host)	8080	80

ローカル環境にCentos7.2サーバーを立ち上げる

• バックエンド用とフロントエンド用のサーバーを別々に立ち上げた時のメモ
• ローカル環境でいくつも仮想環境を立ち上げて開発作業などを行う際などに、ポートが衝突してVagrantが起動出来ない場合がある。そんな時はポートを指定して上げることでポートの衝突を回避できる。

[サーバー仕様]

設定	フロントエンド	備考
OS	centos7
hostname	front	設定するとVirtual Boxのマシン名になった気がする
public ip	192.168.0.50
private ip	192.168.33.50
tcp port(guest)	80
tcp port(host)	80
ssh port(guest)	2200
ssh port(host)	2200
udp port(guest)	2222	上記ポートが衝突した際にudpを利用
udp port(host)	2222	上記ポートが衝突した際にudpを利用
