說明： 210，104作為mysql數(shù)據(jù)庫.
208作為mysql-proxy.
106作為測(cè)試機(jī)器.

相關(guān)軟件下載：
lua
www.lua.org
mysql-proxy
http://mysql.cdpa.nsysu.edu.tw/Downloads/MySQL-Proxy/

1. 在208上安裝lua

#tar zxvf lua-5.1.4.tar.gz -C /usr/local
# cd /usr/local
#mv lua-5.1.4 lua
#cd lua
#make //make之后可以看到系統(tǒng)列表,下面的
命令要用到
#make linux //我這里是linux

#make install

2.安裝mysql-proxy

# tar -zxvf mysql-proxy-0.6.0-linux-rhas4-x86.tar.gz -C /usr/local/
# cd /usr/local/
# mv mysql-proxy-0.6.0-linux-rhas4-x86 mysql-proxy
# export PATH=$PATH:/usr/local/mysql-proxy/sbin/
#mysql-proxy --proxy-read-only-backendaddresses=192.168.100.210:3306
--proxy-backend-addresses=192.168.100.104:3306
--proxy-lua-script=/home2/mysql-proxy-0.6.0-linux-rhas4-x86/share/mysql-proxy/rw-splitting.lua &

3.在210,104上設(shè)置權(quán)限
mysql> grant all privileges on backup.* to
[email=backup@'%']backup@'%'[/email]
identified by 'shenxun';
//這里給個(gè)賬號(hào)backup,密碼shenxun,讀寫操作的數(shù)據(jù)庫是backup.

4.進(jìn)行測(cè)試.

用106連接208的mysql-proxy：

/usr/bin/mysql -u backup -pshenxun
