同一臺MySQL服務器啓動多個端口

wget  二進制的源碼包

解壓 
cat INSTLL-BINARY 
根據說明操作，具體安裝步驟請看 http://www.lishiming.net/thread-7-1-1.html 
其中1-4步驟是相同的，第5步，也是最重要的一步，要初始化數據庫
因爲是多個端口，所以要根據配置文件來初始化多個數據庫
比如說有2個端口
則要運行兩次 
./scripts/mysql_install_db --datadir=/home/mysql1 --user=mysql
./scripts/mysql_install_db --datadir=/home/mysql2 --user=mysql

配置文件要編輯成這樣
[mysqld0]
port            = 3300
socket          = /tmp/mysql0.sock
pid-file        = /home/mysql0/localhost.localdomain0.pid
datadir         = /home/mysql0
#log            = /data/mysql0/mysql0.log
user            = mysql
skip-locking
skip-name-resolve
#skip-bdb
#skip-innodb
key_buffer = 128M
max_allowed_packet = 1M
table_cache = 864
sort_buffer_size = 1M
read_buffer_size = 512K
read_rnd_buffer_size = 1M
myisam_sort_buffer_size = 32M
thread_cache_size = 16
query_cache_size = 32M
thread_concurrency = 8
#skip-networking

把配置文件放在 /etc/my.cnf

最後就該啓動了 
/usr/local/mysql/bin/mysqld_multi start 0-1  這裏的0或1是根據配置文件中"[mysqld0]"來定的。
