mysql启动多个mysqld

linking

安装mysql-3.23.58-pc-linux-i686.tar,解压出来之后,运行scripts/mysql_install_db,create user mysql,运行bin/safe_mysqld结果发现开了很多/app/remind/mysql/bin/mysqld --defaults-extra-file=/app/remind/mysql/data/my.cnf --basedir=/app/remind/mysql --datadir=/app/remind/mysql/data --pid-file=/app/remind/mysql/data/localhost.localdomain.pid --skip-locking
的线程
如下:


appadmin  2749  2299  0 18:07 pts/1    00:00:00 /bin/sh bin/safe_mysqld
appadmin  2759  2749  0 18:07 pts/1    00:00:00 /app/remind/mysql/bin/mysqld --defaults-extra-file=/app/remind/mysql/data/my.cnf --basedir=/app/remind/mysql --datadir=/app/remind/mysql/data --pid-file=/app/remind/mysql/data/localhost.localdomain.pid --skip-locking
appadmin  2760  2759  0 18:07 pts/1    00:00:00 /app/remind/mysql/bin/mysqld --defaults-extra-file=/app/remind/mysql/data/my.cnf --basedir=/app/remind/mysql --datadir=/app/remind/mysql/data --pid-file=/app/remind/mysql/data/localhost.localdomain.pid --skip-locking
appadmin  2761  2760  0 18:07 pts/1    00:00:00 /app/remind/mysql/bin/mysqld --defaults-extra-file=/app/remind/mysql/data/my.cnf --basedir=/app/remind/mysql --datadir=/app/remind/mysql/data --pid-file=/app/remind/mysql/data/localhost.localdomain.pid --skip-locking


但我以前安装linux自带的mysql,再删除.用他设置好的基础环境.再按照上面的操作来做,只会产生一个这样的进程?

是不是我还有哪些地方漏了!?不过应该启动不成功才对,现在一切正常,只是进程多了. PS:版本都是一模一样的文件.
