你好：我今天在安装部署TIDB时采用的是v3.0文档里面的[使用 TiDB Ansible 部署 TiDB 集群]部署方式，但是搭建过程中出现了错误，烦请帮忙解答一下，谢谢！具体信息如下： 1、操作系统版本： CentOS Linux release 7.7.1908 (Core) 2、下载的版本： git clone -b v3.0.2 https://github.com/pingcap/tidb-ansible.git 3、执行如下命令报错：

你好，

尝试执行 sudo pip install --upgrade pip ，看是否解决问题

建议使用 tiup 部署 3.0及以上版本哦，如果初次部署可以使用 3.0 最新版本：

好的~

您好，目前最新的稳定版本是哪几个版本？

来了老弟 · 2020 年4 月 13 日 09:42

你好，

目前使用最多的是 3.0 版本， 3.0.12（最新版）即可，可以看下 release note：

https://pingcap.com/docs-cn/stable/releases/3.0.12/

kaizhi · 2020 年4 月 13 日 09:44

你好！执行 `sudo pip install --upgrade pip，换成3.0.12还是报同样的错误 [root@TIDB-02 ~]# sudo pip install --upgrade pip Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f04a1142410>: Failed to establish a new connection: [Errno 101] Network is unreachable’,)’: /simple/pip/ Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f04a1142a50>: Failed to establish a new connection: [Errno 101] Network is unreachable’,)’: /simple/pip/ Retrying (Retry(total=2, connect=None, read=None, redirect=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f04a1142bd0>: Failed to establish a new connection: [Errno 101] Network is unreachable’,)’: /simple/pip/ Retrying (Retry(total=1, connect=None, read=None, redirect=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f04a1142d50>: Failed to establish a new connection: [Errno 101] Network is unreachable’,)’: /simple/pip/ Retrying (Retry(total=0, connect=None, read=None, redirect=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f04a1142ed0>: Failed to establish a new connection: [Errno 101] Network is unreachable’,)’: /simple/pip/ Requirement already up-to-date: pip in /usr/lib/python2.7/site-packages

你好，

ping www.baidu.com

检查下服务器是否可连接外网，感谢！

您好: 我这边生产服务器是代理上网的

kaizhi · 2020 年4 月 14 日 07:26

您好:

我在在中控机上配置部署机器 SSH 互信及 sudo 规则,用tidb用户在中控机上执行如下命令时, ansible-playbook -i hosts.ini create_users.yml -u root -k 报如下错误: [root@TIDB-01 ~]# su - tidb Last login: Tue Apr 14 14:58:26 CST 2020 on pts/0 [tidb@TIDB-01 ~]$ /bin/ansible -i /home/tidb/tidb-ansible/inventory.ini all -m shell -a ‘whoami’ Traceback (most recent call last): File “/bin/ansible”, line 40, in from ansible.errors import AnsibleError, AnsibleOptionsError, AnsibleParserError ImportError: cannot import name AnsibleError [tidb@TIDB-01 ~]$ ansible-playbook -i hosts.ini create_users.yml -u root -k Traceback (most recent call last): File “/bin/ansible-playbook”, line 40, in from ansible.errors import AnsibleError, AnsibleOptionsError, AnsibleParserError ImportError: cannot import name AnsibleError

你好，

上面执行 sudo pip install --upgrade pip 就已经报错网络不通的状态，请检查下先，亦可以提供下 ansible 的版本，如果网络情况良好，按照官网步骤操作是可以成功部署的。

如果有需要可以尝试使用 ansible 离线部署方案
