4.安装psycopg2
安装包==>psycopg2-2.4.1.tar.gz
#tar -zxvf psycopg2-2.4.1.tar.gz
#cd psycopg2-2.4.1
#vi setup.cfg ==>找到# pg_config= 改为 pg_config=数据库路径/PostgreSQL/8.4/bin/pg_config
#python setup.py build_ext
#python setup.py install
5.安装skytools
安装包==>skytools-2.1.12.tar.gz
#vi ~/.bash_profile
在PATH=$PATH:$HOME/bin行下添加
PATH=$PATH:数据库路径/PostgreSQL/8.4/bin
保存后运行source ~/.bash_profile
#tar -zxvf skytools-2.1.12.tar.gz
#cd skytools-2.1.12
#./configure --with-pgconfig=数据库路径/PostgreSQL/8.4/bin/pg_config
#make
#make install
#python setup.py install
配置主从:
主服务器配置
进入主数据库服务器的../skytools-2.1.7/tests/londiste/conf目录，添加文件ticker_test.ini，文件内容：
[pgqadm]
job_name = ticker_test
db = dbname=数据库名称 host=数据库ip地址 port=数据库端口 user=postgres
# how often to run maintenance [minutes]
maint_delay_min = 60
# how often to check for activity [secs]
loop_delay = 0.5
logfile = /usr/local/pgsqllog/log.%(job_name)s
pidfile = /usr/local/pgsqllog/pid.%(job_name)s
use_skylog = 0
connection_lifetime = 21
queue_refresh_period = 10
安装ticker
#pgqadm.py ticker_service.ini install
#pgqadm.py ticker_service.ini ticker -d
从服务器配置
进入从数据库服务器的../skytools-2.1.7/tests/londiste/conf目录，添加文件replic_test_1.ini,文件内容：
[londiste]
job_name = replic_test_1
provider_db = dbname=数据库名称 host=主数据库ip地址 port=数据库端口 user=postgres password=数据库密码
subscriber_db = dbname=数据库名称 host=从数据库ip地址 port=数据库端口 user=postgres password=数据库密码
# it will be used as sql ident so no dots/spaces
pgq_queue_name = londiste_1_replic
logfile = /usr/local/pgsqllog/log.%(job_name)s
pidfile = /usr/local/pgsqllog/pid.%(job_name)s
loop_delay = 0.5
connection_lifetime = 30
安装londiste
#londiste.py replic_test_1.ini provider install
#londiste.py replic_test_1.ini subscriber install
启用replay
#londiste.py replic_test_1.ini replay -d
添加要复制的表
#londiste.py replic_test_1.ini provider add 需要主从复制的表名(可用*号例如:xw*)
#londiste.py replic_test_1.ini subscriber add 需要主从复制的表名(可用*号例如:xw*)
