Tidb ansible部署报错

🪐 TiDB 技术问题
1

你好！ 目前我的环境是Centos 7.7 版本是3.0.12，tidb和pd 共用三台，三台tikv ,中控机单独部署，中控机一台，目标机一台，我在hosts.ini 和inventory.ini里面是否需要添加中控机的信息？在中控机上执行ansible-playbook bootstrap.yml时，报如下错误：

你好，

请检查是否执行 cd /home/tidb/tidb-ansible && \ sudo pip install -r ./requirements.txt 来安装相关依赖，如果出现 pip 相关提示，可以尝试在 python2.7 执行下。

3.0 版本目前可以使用 tiup 进行部署，简单方便，并且没有 ansible 相互的依赖关系可以尝试下。

已经执行过这个命令了,

4

请检查下当前部署用户是否有相关权限，是否在正确的用户下进行操作

我是用tidb 用户执行的如下命令: cd /home/tidb/tidb-ansible sudo pip install -r ./requirements.txt -i https://pypi.doubanio.com/simple --proxy=代理ip

7

需要添加，host.ini 配置集群中所有服务器；inventory.ini 配置各组件的信息。

8

你好,中控机不作为目标机,那中控机的IP部署在哪个位置?

9

你好，

如果中控机不作为组件部署机，也是需要写在 host.ini 中

10

你好 ，我现在部署成功了，但是ansible-playbook start.yml这个命令只能在中控机上执行，其他的目标机执行不了，这条命令能在其他的目标机执行吗

11

您好：

    1. start.yml需要启动所有的pd，tidb，tikv，只有中控机是和所有节点互信联通的。
    2. 其他目标机可以控制自己的节点，在安装目录/scripts/目录下有对应实例的start_xxx.sh和stop_xx.sh控制单个实例的启停
    3. 可以在其他节点安装中控机的方式部署，类似于在其他地方在装一遍中控机，只是不用部署实例。 这样就有两套中控机可以控制了

好的 谢谢！
