我试图在我的酒保设置上配置地理冗余，但是当我尝试从主备份复制到辅助备份时出现错误，我的配置是：

服务器 1

  • 虚拟盒子上的 Ubuntu 18
  • Postgres 12
  • 192.168.0.103
  • /etc/barman.conf
backup_method = rsync
archiver = on
compression = gzip
reuse_backup = link
backup_options = concurrent_backup
parallel_jobs = 2
network_compression = true
basebackup_retry_times = 20
basebackup_retry_sleep = 120
  • /etc/barman.d/comauto_20200921_95
[comauto_20200921_95]
description =  "Comauto Local Postgres 9.5 - 21/09/2020"
conninfo = host=192.168.0.102 user=barman dbname=postgres
ssh_command = ssh postgres@192.168.0.102
retention_policy = RECOVERY WINDOW OF 2 WEEKS
backup_options = exclusive_backup

服务器 2

  • 虚拟盒子上的 Ubuntu 18
  • Postgres 9.5
  • ifconfig = 192.168.0.102
  • /etc/barman.conf
backup_method = rsync
archiver = on
compression = gzip
reuse_backup = link
backup_options = concurrent_backup
parallel_jobs = 2
network_compression = true
basebackup_retry_times = 20
basebackup_retry_sleep = 120
; the only difference
primary_ssh_command = barman@192.168.0.103
  • /etc/barman.d/comauto_20200921_95
[comauto_20200921_95]
description =  "Comauto Local Postgres 9.5 - 21/09/2020"
conninfo = host=192.168.0.102 user=barman dbname=postgres
ssh_command = ssh postgres@192.168.0.102
retention_policy = RECOVERY WINDOW OF 2 WEEKS
backup_options = exclusive_backup

在服务器 1 上：

sudo su barman
ssh barman@192.168.0.102 -C true
 # OK
barman check comauto_20200921_95
 # All OK
barman backup comauto_20200921_95
 # OK
barman list-backup comauto_20200921_95
 # comauto_20200921_95 20201111T172643 - Wed Nov 11 17:26:50 2020 - Size: 6.2 GiB - WAL Size: 0 B
 # comauto_20200921_95 20201111T114656 - Wed Nov 11 11:47:08 2020 - Size: 6.2 GiB - WAL Size: 79.9 KiB
 # comauto_20200921_95 20201111T112906 - Wed Nov 11 11:33:10 2020 - Size: 6.2 GiB - WAL Size: 96.4 KiB

错误发生在这里

在服务器 2 上：

sudo su barman
ssh barman@192.168.0.103 -C true
 # OK
barman check comauto_20200921_95
 # WAL archive: FAILED
 # ssh: FAILED (Connection failed using 'barman@192.168.0.103 -o BatchMode=yes -o StrictHostKeyChecking=no' return code 127)
barman cron
 # ERROR: Failed to retrieve the primary node status: sync-info execution on remote primary server comauto_20200921_95 failed: /bin/sh: 1: barman@192.168.0.103: not found
barman list-backup comauto_20200921_95

一个明显的问题是primary_ssh_command缺少实际的ssh；大概应该是：

; the only difference
primary_ssh_command = ssh barman@192.168.0.103

请参阅此处文档中的示例：https ://docs.pgbarman.org/#configuration-1
