MySQL8.0InnodbCluster部署⽂档（内含基于MGR使⽤mysqlshell。。。⽂章⽬录
⼀、环境说明
1.1 版本说明
软硬件信息参数
配置2C4G
操作系统版本CentOS Linux release 7.7.1908 (Core)
内核版本  3.10.0-1062.el7.x86_64
MySQL版本MySQL 8.0.20
MySQL Shell版本MySQL Shell 8.0.20
MySQL Router版本MySQL Router 8.0.20
1.2 服务器规划
服务器IP端⼝⾓⾊
node1192.168.137.863306Master，shell，router
node2192.168.137.873306Slave
node3192.168.137.883306Slave
1.3 配置⽬录规划
软件⽬录
MySQL软件安装⽬录/usr/local/mysql/mysqlserver
MySQL数据⽂件⽬录/data/mysql/data
MySQL⽇志⽂件⽬录/data/mysql/logs
MySQLbinlog⽇志⽬录/data/mysql/binlog
MySQL配置⽂件⽬录/etc/myf
MySQL Shell安装⽬录/usr/local/mysql
MySQL Router安装⽬录/usr/local/mysql/mysqlserver
⼆、基础配置
所有3个节点都执⾏下述操作
2.1 关闭selinux和防⽕墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
2.2 配置IP域名映射
cat /etc/hosts
127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4
:
:1        localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.137.86 node1
192.168.137.87 node2
192.168.137.88 node3
2.3 更改I/O调度模式
echo deadline > /sys/block/sda/queue/scheduler
cat /sys/block/sda/queue/scheduler
2.4 ⽂件系统选择
  ⽂件系统最好选择xfs，它⽐ext4更⽅便管理。
2.5 操作系统调优
cat>>/f <<EOF
vm.swappiness = 0
fs.aio-max-nr = 1048576
fs.file-max = 681574400
kernel.shmmax = 137438953472
kernel.shmmni = 4096
kernel.sem = 250 32000 100 200
net.ipv4.ip_local_port_range = 9000 65000
EOF
cat>>/etc/f <<EOF
mysql soft nproc 65536
mysql hard nproc 65536
mysql soft nofile 65536
mysql hard nofile 65536
EOF
cat>>/etc/profile<<EOF
if [ $USER = "mysql" ]; then
ulimit -u 16384 -n 65536
fi
EOF
2.6 关闭numa
# sed -i 's/GRUB_CMDLINE_LINUX.*/GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos\/root rd.lvm.lv=centos\/swap rhgb quiet numa=off"/g' /e tc/default/grub
# grub2-mkconfig -o /etc/grub2.cfg
# cat /etc/grub2.cfg
# reboot
# cat /proc/cmdline
# dmesg | grep -i numa
三、部署MySQL
3.1 创建MySQL⽤户组和⽤户
groupadd mysqlmysql帮助文档
useradd -g mysql mysql -s /sbin/nologin
id mysql
3.2 配置⽬录
mkdir -pv /data/mysql/{data,logs,binlog,tmp,redo}
chown -R mysql:mysql /data/mysql/
2.3 解压安装包
mkdir /usr/local/mysql/program -pv
tar xf mysql-8.0.20-el7-x86_64.tar -C /usr/local/mysql/program/
cd /usr/local/mysql/program/
tar xf mysql-8.0.20-el7-x86_ -C /usr/local/mysql/
tar xf mysql-test-8.0.20-el7-x86_  -C /usr/local/mysql/
tar xf mysql-router-8.0.20-el7-x86_ -C /usr/local/mysql/
2.4 软链接程序⽬录并配置环境变量
ln -s /usr/local/mysql/mysql-8.0.20-el7-x86_64/ /usr/local/mysql/mysqlserver
ln -s /usr/local/mysql/mysql-router-8.0.20-el7-x86_64/ /usr/local/mysql/mysqlrouter
export PATH=/usr/local/mysql/mysqlserver/bin:/usr/local/mysql/mysqlrouter/bin:$PATH
echo 'export PATH=/usr/local/mysql/mysqlserver/bin:/usr/local/mysql/mysqlrouter/bin:$PATH' >> /etc/profile source /etc/profile
