如何快速使用mysqlreplicate搭建MySQL主从

[root@HE1 ~]# tar xvf mysql-utilities-1.5.4.tar.gz

[root@HE1 ~]# cd mysql-utilities-1.5.4

[root@HE1 mysql-utilities-1.5.4]# python setup.py build

[root@HE1 mysql-utilities-1.5.4]# python setup.py install

[root@HE1 ~]# mysqlreplicate --help
MySQL Utilities mysqlreplicate version 1.5.4 
License type: GPLv2
Usage: mysqlreplicate --master=root@localhost:3306 --slave=root@localhost:3310 --rpl-user=rpl:passwd 
mysqlreplicate - establish replication with a master
Options:
 --version show program's version number and exit
 --help display a help message and exit
 --license display program's license and exit
 --master=MASTER connection information for master server in the form:
 <user>[:<password>]@<host>[:<port>][:<socket>] or
 <login-path>[:<port>][:<socket>] or <config-
 path>[<[group]>].
 --slave=SLAVE connection information for slave server in the form:
 <user>[:<password>]@<host>[:<port>][:<socket>] or
 <login-path>[:<port>][:<socket>] or <config-
 path>[<[group]>].
 --rpl-user=RPL_USER the user and password for the replication user
 requirement, in the form: <user>[:<password>] or
 <login-path>. E.g. rpl:passwd
 -p, --pedantic fail if storage engines differ among master and slave.
 --test-db=TEST_DB database name to use in testing replication setup
 (optional)
 --master-log-file=MASTER_LOG_FILE
 use this master log file to initiate the slave.
 --master-log-pos=MASTER_LOG_POS
 use this position in the master log file to initiate
 the slave.
 -b, --start-from-beginning
 start replication from the first event recorded in the
 binary logging of the master. Not valid with --master-
 log-file or --master-log-pos.
 --ssl-ca=SSL_CA The path to a file that contains a list of trusted SSL
 CAs.
 --ssl-cert=SSL_CERT The name of the SSL certificate file to use for
 establishing a secure connection.
 --ssl-key=SSL_KEY The name of the SSL key file to use for establishing a
 secure connection.
 --ssl=SSL Specifies if the server connection requires use of
 SSL. If an encrypted connection cannot be established,
 the connection attempt fails. By default 0 (SSL not
 required).
 -v, --verbose control how much information is displayed. e.g., -v =
 verbose, -vv = more verbose, -vvv = debug
 -q, --quiet turn off all messages for quiet execution.
