1. sudo yum update
   sudo yum install git
   sudo yum groupinstall -y 'development tools'
   sudo yum install -y gcc-c++ glibc-headers openssl-devel readline libyaml-devel readline-devel zlib zlib-devel  sqlite-devel

   1. gem install rails

postgresql

1. sudo yum install postgresql-server postgresql-contrib postgresql-devel
2. sudo postgresql-setup initdb
3. nano /var/lib/pgsql/data/pg_hba.conf
   1. 외부 접속 허용하기 [pg_hba.conf]
      1. host    all     all     0.0.0.0/0       password
   2. rails와의 연결을 위해 md5로 암호화 설정
      1. local   all             all                                     md5
         host    all             all             127.0.0.1/32            md5
4. nano /var/lib/pgsql/data/postgresql.conf
   1. 외부 접속 허용하기 2 [postgresql.conf]
      1. #listen_address = 'localhost' 에서 listen_address = '*'로 수정.
5. 계정 생성
   1. postgres로 로그인
      1. sudo su - postgres 
   2. Create a PostgreSQL superuser user with this command (substitute the highlighted word with your own username):
      1. createuser -s pguser
   3. To set a password for the database user, enter the PostgreSQL console with this command: 
      1. psql
   4. The PostgreSQL console is indicated by the postgres=# prompt. At the PostgreSQL prompt, enter this command to set the password for the database user that you created:
      1. \password pguser
   5. Enter your desired password at the prompt, and confirm it. Now you may exit the PostgreSQL console by entering this command: 
      1. \q 
   6. Now that your PostgreSQL user is set up, switch back to your normal user:
      1. exit
6. 방화벽 개방

      2. PONG [PONG이 안오면 실패]

머신 초기 세팅 [디스크 할당 및 폴더 설정]

#디스크 목록 보기

• fdisk -l

 

#디스크 할당

• fdisk /dev/[디스크명]

• 이후 옵션은 http://yonoo88.tistory.com/651 참조

 

#디스크 초기화 [ext4로 초기화] 아래 디스크3은 nextmv에서 제공해준 디스크가 500gb씩 분리되어있는 3개의 디스크만 사용할 것 이므로.

• mkfs.ext4 /dev/xvdg1

• mkfs.ext4 /dev/xvde1

• mkfs.ext4 /dev/xvdc1

 

#ext 폴더 생성

• cd /usr/local

• mkdir ext1

• mkdir ext2

• mkdir ext3

 

#디스크 마운트

• mount -t ext4 /dev/xvdg1 /usr/local/ext1

• mount -t ext4 /dev/xvde1 /usr/local/ext2

• mount -t ext4 /dev/xvdc1 /usr/local/ext3

 

#db 데이터 복사

• cp -r /var/lib/pgsql/data /usr/local/ext2

 

#폴더 권한 설정

• chmod -R 700 /usr/local/ext2

• chown -R postgres:postgres /usr/local/ext2

 

#PGDATA 경로 수정.

• nano /usr/lib/systemd/system/postgresql.service

• /usr/local/ext2/data

• systemctl daemon-reload

• service postgresql restart
• 해당 작업 이후에는 설정 파일 경로가 /usr/local/ext2/data 로 바뀌는 점에 유의하자.
