What are the good points of virtual machines?

I'm working to move my personal financial system which is running on a physical machine to virtual machine because its simplicity of maintenance and portability. currently I'm running the system on tower form PC, but it makes annoying noise, and it consumes power much, so I'm going to make the system virtual, and move it to my old MacBook or something.

Backup of virtual machines are so easy because it exists as regular files in the physical machine, and it can be automated easily thanks to OS X's TimeMachine and VMware Fusion's snapshot. and I can easily move its machine running on in case I need to do it. when I want to do some heavy calculation, I can easily copy the whole of the virtual machine to another high-performance environment anytime while running it on low power-consuming machine regularly.

Installation 

VMware Fusion 6.0.2 supplies "easy installation" function for CentOS 6.5 (not for 7.0). which answers annoying questions instead of me during installation process. all I need to answer were username and password to use. then, VMware will getting almost all of my work done contains installation of VMware Tools. several minutes after, you'll see GUI login prompt. for my purpose GUI is unnecessary but I don't want to do these annoying work by myself so I just followed this way.

I made some changes before installation begins such as following:

• Increase HDD size to 384GB (There's no need to reserve that actual size in the host machine. actual size increases with actual use in the virtual machine. Increasing of size is impossible when snapshots available, but it's possible after deleting all of snapshots)
• Increase CPU number to 2
• Increate amount of memory to 2GB
• Set network interface to physical (I want to login via ssh from my LAN)
• Enable VNC daemon

[kyle@localhost ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3       374G  2.6G  353G   1% /
tmpfs           935M  228K  935M   1% /dev/shm
/dev/sda1       291M   39M  238M  14% /boot

環境

• さくらインターネット VPS 1G
• CentOS 6.5
• WildFly 8.0.0CR1
• Apache 2.2.24
• tomcat-connectors-1.2.37-src.tar.gz
• ここに書いた作業をした後

何をするの？

ApacheとWildFlyをmod_jkで繋ぎます

mod_jkを入れる

ビルドとインストール

yumとかでインストール出来れば楽なのですが、見当たらなかったのでここからソースを取ってきます

sudo yum install httpd-devel
tar zxvf tomcat-connectors-1.2.37-src.tar.gz
cd tomcat-connectors-1.2.37-src/native
./configure --with-apxs=/usr/sbin/apxs
make -j 2
sudo make install

設定ファイルの雛型をコピー

sudo cp tomcat-connectors-1.2.37-src/conf/httpd-jk.conf /etc/httpd/conf.d
sudo cp tomcat-connectors-1.2.37-src/conf/workers.properties.minimal /etc/httpd/conf/workers.properties
sudo service httpd restart

動作確認

jk-status画面を表示したいのですが、localhostからのアクセスしか許可してないので、sshのトンネル経由でアクセスしてみる。手元の端末で以下を実行

ssh [SERVER ADDRESS] -L 10080:localhost:80

その後ブラウザでここを開いてみると

まだWildFly側で受け入れの設定はしてないけど一応動いてますね

WildFly側の設定

CLIの管理コンソールを起動する

sudo -u wildfly /usr/local/wildfly/bin/jboss-cli.sh

設定コマンドを打ち込む

connect
/subsystem=undertow/server=default-server/ajp-listener=myListener:add(socket-binding=ajp, scheme=http, enabled=true)
exit

こういう感じになればOK

$ sudo -u wildfly /usr/local/wildfly/bin/jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /] connect
[standalone@localhost:9990 /] /subsystem=undertow/server=default-server/ajp-listener=myListener:add(socket-binding=ajp, scheme=http, enabled=true)
{"outcome" => "success"}
[standalone@localhost:9990 /]

telnetで覗いてみる

ちゃんとポートが開いているようです

$ telnet localhost 8009
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
^]

telnet> quit
Connection closed.
$ 

Apache側の設定

ここではとりあえず何も考えず全部WildFlyに飛ばすことにします

sudo sh -c 'cat > /etc/httpd/conf.d/jk.conf' <<EOF
<IfModule jk_module>
    JkMount /* lb
</IfModule>
EOF
sudo service httpd restart
]]>

終わったらグローバルIPアドレス経由でアクセスしてみましょう。

単純な設定しかしてませんがとりあえず繋がったようですね。管理コンソールは9990番ポート経由でないとアクセス出来ないので、リモートから80番経由で管理コンソールを触られる心配はないようです。

環境

• さくらインターネット VPS 1G
• CentOS 6.5
• ここに書いた作業をした後

何をするの？

1. JRE (jre-7u51-linux-x64.rpm) を入れる
2. WildFly (wildfly-8.0.0.CR1.tar.gz) を入れる
3. PostgreSQL 9.2.6を入れる
4. Apacheを入れる

JREを入れる

いまのところこのへんにあります。私はjre-7u51-linux-x64.rpmを取ってきました。

<![CDATA[
sudo rpm -ivh jre-7u51-linux-x64.rpm
]]>

動作確認

$ java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
$ 

WildFlyを入れる

ユーザを作ります

sudo useradd wildfly

tarballを展開します

sudo tar zxvf wildfly-8.0.0.CR1.tar.gz -C /usr/local --no-same-owner
sudo chown -R wildfly:wildfly /usr/local/wildfly-8.0.0.CR1
sudo ln -s /usr/local/wildfly-8.0.0.CR1 /usr/local/wildfly

設定ファイルを作ります

sudo mkdir /etc/java
sudo sh -c 'cat > /etc/java/java.conf' <<EOF
export JAVA_HOME=/usr/java/default
EOF
sudo sh -c 'cat > /etc/default/wildfly.conf' <<EOF
export JBOSS_HOME=/usr/local/wildfly
export JBOSS_USER=wildfly
export LANG=ja_JP.UTF-8
EOF

ログとpid出力用のディレクトリを作ります

sudo mkdir /var/run/wildfly
sudo mkdir /var/log/wildfly

起動スクリプトを置きます

sudo cp /usr/local/wildfly-8.0.0.CR1/bin/init.d/wildfly-init-redhat.sh /etc/init.d/wildfly
sudo chkconfig --add wildfly
sudo chkconfig wildfly on

起動してみます

$ sudo service wildfly start
Starting wildfly:                                          [  OK  ]
$

ログとpidファイルを確認してみます

$ ls -l /var/log/wildfly
合計 8
-rw-r--r-- 1 root root 4670  1月 19 11:54 2014 console.log
$ ls -l /var/run/wildfly
合計 4
-rw-r--r-- 1 wildfly wildfly 6  1月 19 11:54 2014 wildfly.pid
$

listenしているポートを確認してみます

$ netstat -an | grep LISTEN | grep tcp
tcp        0      0 127.0.0.1:9999              0.0.0.0:*                   LISTEN

$ 

WildFlyの管理ユーザを作ります

別に今すぐは使いませんが一応。

sudo -u wildfly /usr/local/wildfly/bin/add-user.sh [USERNAME] [PASSWORD]

Webの管理コンソールから設定状況を見てみます

手元の端末でトンネルを作ります

ssh [IP ADDRESS] -L 10080:localhost:80 -L 19990:localhost:9990

ここにアクセスするとトンネル経由でWebの管理コンソールにアクセス出来ます。ユーザ名とパスワードは先ほど入力した物を使います。

止めてみます

$ sudo service wildfly stop
Stopping wildfly:                                          [  OK  ]
$ ps -Af | grep java
kyle     25222 24452  0 11:58 pts/0    00:00:00 grep java
$

PostgreSQLを入れる

インストール

<![CDATA[
sudo yum install http://yum.postgresql.org/9.2/redhat/rhel-6-x86_64/pgdg-centos92-9.2-6.noarch.rpm
sudo yum install postgresql92-server postgresql92-contrib
sudo service postgresql-9.2 initdb
sudo chkconfig postgresql-9.2 on
]]>

WildFlyから接続できるように認証方式を変更する

sudo -u postgres cp /var/lib/pgsql/9.2/data/pg_hba.conf /var/lib/pgsql/9.2/data/pg_hba.conf.bak
sudo -u postgres sed -i -e "s/^host    all             all             127.0.0.1\/32            ident/host    all             all             127.0.0.1\/32            md5/" /var/lib/pgsql/9.2/data/pg_hba.conf

動かしてみる

$ sudo service postgresql-9.2 start
Starting postgresql-9.2 service:                           [  OK  ]
$

Apacheを入れる

インストール

sudo yum install httpd
sudo chkconfig httpd on

動かしてみる

$ sudo service httpd start
Starting httpd:                                            [  OK  ]
$

アクセスしてみる

普通に手元の端末のブラウザからアクセス可。
