[설치] 하나의 서버에서 mysql 데몬 두개 실행

간단하게 특별한 설명 없이 적습니다.

/usr/local/mysql 에 소스 컴파일 된 mysql 이 위치

/etc/rc.d/init.d/mysqld start 실행시 /etc/my.cf 를 참조하여 실행됨.

특별한 옵션 없이 실행 상태 모습

[root@arh01 /]# ps aux | grep mysqld

root     32362  0.0  0.0  4184 1084 pts/2    S    15:46   0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe –datadir=/usr/local/mysql/data –pid-file=/usr/local/mysql/data/arh01.clunix.ms.pid

mysql    32389  0.0  0.7 124688 15528 pts/2  Sl   15:46   0:00 /usr/local/mysql/libexec/mysqld –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –user=mysql –pid-file=/usr/local/mysql/data/arh01.clunix.ms.pid –skip-locking –port=3306 –socket=/tmp/mysql.sock

밑에 옵션을 이용해서 두번째 데몬 실행

당연히 데이터 베이스는 복사해 놓고…

팁 데이터 베이스 데이터 디렉은 카피 하시게 되면 user mysql로 그 하위 디렉터리까지 해주어야 실행 됩니다.

# ./mysqld_safe –basedir=/usr/local/mysql –datadir /usr/data –port=3307 –socket=/tmp/mysql1.sock –pid-file=/tmp/mysqld.pid &

새로운 포트로 접속 옵션

mysql -P 3307 -u root -p password

[root@arh01 /]# ps aux | grep mysqld

간단 테스트 였습니다.
