tidb单机部署文档

1、创建用户

#创建用户
useradd tidb
#设置密码
passwd tidb

2、配置免密码登录

编辑/etc/sudoers文件,文末加入：
tidb ALL=(ALL)  NOPASSWD:ALL如果想要控制某个用户(或某个组用户)只能执行root权限中的一部分命令, 
或者允许某些用户使用sudo时不需要输入密码，一般修改/etc/sudoers文件cat >> /etc/sudoers << "EOF"
tidb ALL=(ALL)  NOPASSWD:ALL
EOF

3、创建免密认证

# 切换用户
su - tidb
# 执行命令，一直按回车键就行
ssh-keygen -t rsa

4、创建目录

mkdir /data/businessServer/tidb/  -p
上传安装包
解压安装包
tar xf  tidb-community-server-v7.1.0-linux-amd64.tar.gz执行初始化脚本

source /home/tidb/.bash_profile

至此，TiDB安装所需的组件已经安装完成

5、配置初始化参数文件

topology.yamlcat >topology.yaml<<'EOF'
global:user: "tidb"ssh_port: 22deploy_dir: "/data/tidb/deploy"data_dir: "/data/tidb/data"# # Monitored variables are applied to all the machines.

EOF

6、初始化并启动集群

tiup cluster deploy  kylin-tidb-test  v7.1.0 /data/businessServer/tidb/conf/topology.yaml  -uroot -p
tiup cluster start kylin-tidb-test --init
