ansible yum 安装慢的问题解决

使用ansible yum 模块安装软件时,可能会碰到执行非常慢的情况。

- name: install rpms
  yum:
    name:
      - etcd
    state: latest
    disablerepo: "*"
    enablerepo: some

原因可能是/etc/yum.conf配置的默认yum源响应非常慢,甚至不可达。

解决办法是增加配置项 install_repoquery: no,如下:

- name: install rpms
  yum:
    name:
      - etcd
    state: latest
    disablerepo: "*"
    enablerepo: some
    install_repoquery: no

install_repoquery默认配置是yes。官方释义如:

If repoquery is not available, install yum-utils. If the system is registered to RHN or an RHN Satellite, repoquery allows for querying all channels assigned to the system. It is also required to use the 'list' parameter.
NOTE: This will run and be logged as a separate yum transation which takes place before any other installation or removal.
NOTE: This will use the system's default enabled repositories without regard for disablerepo/enablerepo given to the module.

重点看最后面: 配置为yes时会使用系统默认启用的yum源,即使你配置了disablerepoenablerepo
