Barman 安装

Barman需要用到psql客户端，所以需要在Barman服务器安装psql数据库

1 linux操作系统环境准备：

python版本：2.6或2.7
yum -y install epel-release.noarch
yum -y install python-argcomplete.noarch
yum -y install python-argh.noarch
yum -y install python-psycopg2.x86_64 python-psycopg2-doc.x86_64
yum -y install python-dateutil.noarch python-dateutil15.noarch
yum -y install rsync.x86_64

2 创建barman系统用户
groupadd barman
useradd -g barman barman
passwd barman

3 安装Barman
# tar -zxvf barman-1.4.0.tar.gz
# chown -R barman:barman barman-1.4.0

[barman@localhost barman-1.4.0]$ ./setup.py build
[root@localhost barman-1.4.0]# ./setup.py install
[root@localhost barman-1.4.0]# su - barman
[barman@localhost ~]$ cd /software/barman-1.4.0
[barman@localhost barman-1.4.0]$ ./setup.py install --user

将Barman配置文件Barman.conf拷贝到~/.barman.conf
[barman@localhost ~]$ cp /software/barman-1.4.0/doc/barman.conf ~/.barman.conf
[barman@localhost ~]$ ls -al
-rw-r--r--  1 barman barman 2863 Feb 12 15:57 .barman.conf

4 配置.barman.conf文件：
[main-test]
description =  "test"
ssh_command = ssh barman@barmanIP
conninfo = host=IP user=postgres
incoming_wals_directory: /barman_backup/main-test/incoming
minimum_redundancy = 1
retention_policy = REDUNDANCY 2

5 Barman服务器与数据库服务器之间做互信
[barman@localhost ~]$ ssh-keygen -t rsa
[barman@localhost ~]$ ssh-copy-id -i .ssh/id_rsa.pub barman@IP
[barman@localhost ~]$ ssh barman@IP

[barman@erp ~]$ ssh-keygen -t rsa
[barman@erp ~]$ ssh-copy-id -i .ssh/id_rsa.pub barman@barmanIP
[barman@erp ~]$ ssh barman@barmanIP

6 基于时间点的恢复： --基于时间的恢复将数据库恢复到read only状态
[barman@slony ~]$ barman recover --target-time "2015-02-27 15:25:00" --remote-ssh-command "ssh postgres@IP" main-test 20150227T141803 /home/postgres/pgdata

**********************************************************************************
Barman备份standby数据库：

在standby库操作：
安装pgespresso-master.zip       --https://github.com/2ndquadrant-it/pgespresso
[postgres@segdb1 pgespresso-master]$ make
[postgres@segdb1 pgespresso-master]$make install

[postgres@segdb1 ~]$ psql
postgres=# CREATE EXTENSION pgespresso;

在Barman服务器：
vi .barman.conf
添加
backup_options = concurrent_backup

注：
必须将主服务器的归档日志归档到：/home/barman/barman/main-test-standby/incoming目录下
archive_command = 'rsync -a %p barman@barmanIP:/barman_backup/main-test/incoming/%f'
