Tarantool

無法執行 Tarantool 複製

  • May 21, 2021

我正在嘗試從文件中重現 tarantool 主複製

所以我為每個目錄製作了master/master.lua, rep1/rep1.lua, , cd 並執行它，但它顯示了類似這樣的內容（10 多分鐘，沒有進展）：rep2/rep2.lua

程式碼在這裡：

master.lua

box.cfg{
 listen = 13301,
       replication = {'replicator:password@127.0.0.1:23301',  -- master URI
                'replicator:password@127.0.0.1:33301'}, -- replica URI
 read_only = false
}
box.once("schema", function()
  box.schema.user.create('replicator', {password = 'password'})
  box.schema.user.grant('replicator', 'replication') -- grant replication role
  box.schema.space.create("test")
  box.space.test:create_index("primary")
  print('box.once executed on master')
end)

rep1.lua

box.cfg{
 listen = 23301,
 replication = {'replicator:password@127.0.0.1:13301',  -- master URI
                'replicator:password@127.0.0.1:33301'}, -- replica URI
 read_only = true
}
box.once("schema", function()
  box.schema.user.create('replicator', {password = 'password'})
  box.schema.user.grant('replicator', 'replication') -- grant replication role
  box.schema.space.create("test")
  box.space.test:create_index("primary")
  print('box.once executed on replica 1')
end)

rep2.lua

box.cfg{
 listen = 33301,
 replication = {'replicator:password@127.0.0.1:13301',  -- master URI
                'replicator:password@127.0.0.1:23301'}, -- replica URI
 read_only = true
}
box.once("schema", function()
  box.schema.user.create('replicator', {password = 'password'})
  box.schema.user.grant('replicator', 'replication') -- grant replication role
  box.schema.space.create("test")
  box.space.test:create_index("primary")
  print('box.once executed on replica 2')
end)

它出什麼問題了？

沒關係，我不好，第一條複製線應該是主線，所以它應該是這樣的：

       replication = {'replicator:password@127.0.0.1:13301',  -- master URI
                'replicator:password@127.0.0.1:23301', -- replica URI
                'replicator:password@127.0.0.1:33301'}, -- replica URI
