同一台MySQL服务器启动多个端口

参考网站:http://mylinux.5d6d.net/thread-63-1-1.html

wget 二进制的源码包

解压

cat INSTLL-BINARY

根据说明操作，具体安装步骤请看 http://mylinux.5d6d.com/thread-7-1-1.html
其中1-4步骤是相同的，第5步，也是最重要的一步，要初始化数据库

因为是多个端口，所以要根据配置文件来初始化多个数据库

比如说有2个端口

则要运行两次

./scripts/mysql_install_db --datadir=/home/mysql1 --userdir=mysql

./scripts/mysql_install_db --datadir=/home/mysql2 --userdir=mysql

配置文件要编辑成这样

[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

wait_timeout=8

max_connections=512

max_connect_errors = 10000000

max_user_connections=20

#slow_queries=/data/mysql0slowquer.sql

#log_slow_queries=/data/mysql0slowquer.sql

long_query_time=3

log-bin=mysql0-bin

[mysqld1]

port = 3301

pid-file = /home/mysql1/localhost.localdomain1.pid

datadir = /home/mysql1

#log = /data/mysql1/mysql1.log

user = mysql

把配置文件放在 /etc/my.cnf

最后就该启动了

/usr/local/mysql/bin/mysqld_multi start 0-1 这里的0或1是根据配置文件中"[mysqld0]"来定的
