简单的Slony-I设置实例

如何删除slony相关的内容呢。

我再另外找一台机器，安装slony，也安装postgresql（这个是为防止万一而已）

编写脚本：

[postgres@pg100 ~]$ cat remove.sh

#!/bin/sh

CLUSTERNAME=testdb3_cluster

MASTERDBNAME=testdb3

SLAVEDBNAME=testdb3

MASTERHOST=192.168.10.102

SLAVEHOST=192.168.10.101

REPLICATIONUSER=postgres

/usr/local/slony/bin/slonik <<_EOF_

    #--

    # define the namespace the replication system

    # uses in our example it is slony_example

    #--

    cluster name = $CLUSTERNAME;

    #--

    # admin conninfo's are used by slonik to connect to

    # the nodes one for eachnode on each side of the cluster,

    # the syntax is that of PQconnectdb in

    # the C-API

    # --

    node  admin conninfo = 'dbname=$MASTERDBNAME \

           host=$MASTERHOST user=$REPLICATIONUSER';

    node  admin conninfo = 'dbname=$SLAVEDBNAME \

           host=$SLAVEHOST user=$REPLICATIONUSER';

    uninstall node (id = );

    uninstall node (id = );

_EOF_

[postgres@pg100 ~]$

然后运行：

[postgres@pg100 ~]$ sh remove.sh
