第 13 章 更改副本的角色

流程

1. 如果要提升的副本是带有复制协议的 hub，且 hub 在提升后不再将数据发送到其他主机，请删除复制协议：

   1. 列出 hub 上的复制协议：

      # dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt list --suffix "dc=example,dc=com"
      dn: cn=example-agreement,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config
      cn: example-agreement
      ...

      cn 属性包含下一步中所需的复制协议名称。

   2. 从 hub 中删除复制协议：

      # dsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreementdsconf -D "cn=Directory Manager" ldap://server.example.com repl-agmt delete --suffix "dc=example,dc=com" example-agreement

2. 提升实例：

   • 如果您将消费者或 hub 提升到供应商，请输入：

     # dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "supplier" --replica-id 2

     重要

     对于拓扑中的所有供应商，副本 ID 必须是 1 到 65534 之间的唯一整数值。

   • 如果将消费者提升到 hub，请输入：

     # dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"dsconf -D "cn=Directory Manager" ldap://server.example.com replication promote --suffix "dc=example,dc=com" --newrole "hub"

3. 如果新角色中的副本应该向拓扑中其他主机发送更新，则创建复制协议。
