TiUP在线布署TIDB分布式数据库集群
前期准备：
1、安装CentOS7.5，Linux版本要求：
| Linux 操作系统平台 | 版本 |
|---|---|
| Red Hat Enterprise Linux | 7.3 及以上 |
| CentOS | 7.3 及以上 |
| Oracle Enterprise Linux | 7.3 及以上 |
| Ubuntu LTS | 16.04 及以上 |
2、关闭swap
echo "vm.swappiness = 0">> /etc/sysctl.conf
swapoff -a && swapon -a
sysctl -p
3、关闭防火墙
sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service
sudo systemctl status firewalld.service
4、关闭selinux
cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
5、配置NTP服务
6、配置SSH互信及免密登录
7、安装numactl工具
正式安装：
1、在中控机上安装TiUP组件
1)在中控机安装TiUP工具
curl --proto '=https' --tlsv1.2 -sSf | sh
2)设置TiUP环境变量
source .bash_profile
3)确认TiUP是否安装过
which tiup
4)安装TiUP cluster组件
tiup cluster
5)更新TiUP cluster组件至最新版本
tiup update --self && tiup update cluster
6)查看TiUP版本信息
tiup --binary cluster
2 、初始化配置文件
包含最小拓扑的基础上，同时部署 TiFlash。TiFlash 是列式的存储引擎，已经逐步成为集群拓扑的标配。适合 Real-Time HTAP 业务。
