1、汇总
1.1、问题
多套tidb集群的pd 部署在同样的机器，pd的服务相同，导致pd无法启动
版本：2.1.2
1.2、问题及解决
修改相关文件的端口部分解决
2、具体
2.1、具体问题
2.1.1、系统服务
/etc/systemd/system
pd.service
2.1.2、pd的启停脚本
【${deploy_dir}/scripts/start_pd.sh】
#!/bin/bash
set -e
# WARNING: This file was auto-generated. Do not edit!
# All your edit might be overwritten!
sudo systemctl start pd.service
【 ${deploy_dir} /scripts/stop_pd.sh】
#!/bin/bash
set -e
# WARNING: This file was auto-generated. Do not edit!
# All your edit might be overwritten!
sudo systemctl stop pd.service
2.2、修复
tidb中控机：
【1、更改部署的】
/work/tidb/tidb-ansible-2.1/roles/pd/tasks/ systemd_deployment.yml
更改：
service_name: pd- {{ pd_client_port }}
【2、滚动升级的】
/work/tidb/tidb-ansible-2.1/ rolling_update.yml
更改：
- name: stop PD by systemd
systemd: name=pd -{{ pd_client_port }} .service state=stopped
- name: start PD by systemd
systemd: name=pd -{{ pd_client_port }} .service state=started
【3、更改start的】
/work/tidb/tidb-ansible-2.1/ start.yml
- name: start PD by systemd
systemd: name=pd- {{ pd_client_port }} .service state=started
2.3、修复后结果
手动删除目标pd机器的：
${deploy_dir}/scripts/start_pd.sh
${ deploy_dir } /scripts/stop_pd.sh
${ deploy_dir } /scripts/run_pd.sh
中控机重新部署：
ansible-playbook deploy.yml -l pd机器IP
检查：
start_pd.sh
#!/bin/bash
set -e
# WARNING: This file was auto-generated. Do not edit!
# All your edit might be overwritten!
sudo systemctl start pd-10000 .service
stop_pd.sh
#!/bin/bash
set -e
# WARNING: This file was auto-generated. Do not edit!
# All your edit might be overwritten!
sudo systemctl stop pd-10000 .service
