详解绿色版mysql的安装配置

# Example MySQL config file for medium systems.  
#  
# This is for a system with little memory (32M - 64M) where MySQL plays  
# an important part, or systems up to 128M where MySQL is used together with  
# other programs (such as a web server)  
#  
# You can copy this file to  
# /etc/my.cnf to set global options,  
# mysql-data-dir/my.cnf to set server-specific options (in this  
# installation this directory is C:\mysql\data) or  
# ~/.my.cnf to set user-specific options.  
#  
# In this file, you can use all long options that a program supports.  
# If you want to know which options a program supports, run the program  
# with the "--help" option.  

# The following options will be passed to all MySQL clients  
[client]  
#password   = your_password 
port        = 3306 
socket      = /tmp/mysql.sock  

# Here follows entries for some specific programs  

# The MySQL server  
[mysqld]

# Don't listen on a TCP/IP port at all. This can be a security enhancement,  
# if all processes that need to connect to mysqld run on the same host.  
# All interaction with mysqld must be made via Unix sockets or named pipes.  
# Note that using this option without enabling named pipes on Windows  
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)  
# binary logging is required for replication  
log-bin=mysql-bin  

# required unique id between 1 and 2^32 - 1  
# defaults to 1 if master-host is not set  
# but will not function as a master if omitted  
server-id   = 1 

# Replication Slave (comment out master section to use this)  
#  
# To configure this host as a replication slave, you can choose between  
# two methods :  
#  
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -  
#    the syntax is:  
#  
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,  
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;  
#  
#    where you replace <host>, <user>, <password> by quoted strings and  
#    <port> by the master's port number (3306 by default).  
#  
#    Example:  
#  
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,  
#    MASTER_USER='joe', MASTER_PASSWORD='secret';  
#  
# OR  
#  
# 2) Set the variables below. However, in case you choose this method, then  
#    start replication for the first time (even unsuccessfully, for example  
#    if you mistyped the password in master-password and the slave fails to  
#    connect), the slave will create a master.info file, and any later  
#    change in this file to the variables' values below will be ignored and  
#    overridden by the content of the master.info file, unless you shutdown  
#    the slave server, delete master.info and restart the slaver server.  
#    For that reason, you may want to leave the lines below untouched  
#    (commented) and instead use CHANGE MASTER TO (see above)  
#  
# required unique id between 2 and 2^32 - 1  
# (and different from the master)  
# defaults to 2 if master-host is set  
# but will not function as a slave if omitted  
#server-id       = 2 
#  
# The replication master for this slave - required  
#master-host     =   <hostname> 
#  
# The username the slave will use for authentication when connecting  
# to the master - required  
#master-user     =   <username> 
#  
# The password the slave will authenticate with when connecting to  
# the master - required  
#master-password =   <password> 
#  
# The port the master is listening on.  
# optional - defaults to 3306  
#master-port     =  <port> 
#  
# binary logging - not required for slaves, but recommended
