1. 系统环境
1.1 系统拓扑
- 共享集群模式由两台实例组成；
- 测试环境集群配置了两块网卡，但是崖山共享集群只需使用一块网卡。
1.2 硬件资源说明

复制1.3 软件资源说明
操作系统：CentOS Linux release 7.9.2009 (Core)
数据库软件：YashanDB Server Enterprise Edition Release 23.1.1.200 x86_64
两个节点一样。
2. 系统规划
2.1 数据库系统安装规划
这里跟Oracle很大差异，没有VIP、scan ip和独立网段的private ip。
3. 安装前准备
3.1 检查操作系统版本
[root@yasrac01 ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
复制3.2 检查物理内存容量
[root@yasrac01 ~]# free -g
total used free shared buff/cache available
Mem: 7 0 7 0 0 7
Swap: 7 0 7
复制3.3 检查系统架构
[root@yasrac01 ~]# uname -a
Linux yasrac01 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
复制3.4 配置内核参数
以root用户身份在所有集群主机节点上执行如下命令：
sysctl -w vm.swappiness=0
sysctl -w net.ipv4.ip_local_port_range='32768 60999'
sysctl -w vm.max_map_count=2000000
cat >> /etc/sysctl.conf << EOF
vm.swappiness=0
net.ipv4.ip_local_port_range=32768 60999
vm.max_map_count=2000000
EOF
sysctl -p
复制3.5 配置资源限制
以root用户身份在所有集群主机节点上执行如下命令：
cat >> /etc/security/limits.conf << EOF
yashan soft nofile 65536
yashan hard nofile 65536
yashan soft nproc 65536
yashan hard nproc 65536
yashan soft rss unlimited
yashan hard rss unlimited
yashan soft stack 8192
yashan hard stack 8192
EOF
复制这里的yashan用户是集群使用的系统用户，按实际情况调整。
3.6 关闭透明大页
以root用户身份在所有集群主机节点上执行如下命令：
1. cat /sys/kernel/mm/transparent_hugepage/enabled 2. vi /etc/default/grub 在 GRUB_CMDLINE_LINUX 中添加或修改参数 transparent_hugepage=never 3. cat /sys/kernel/mm/transparent_hugepage/enabled 4. grub2-mkconfig -o /boot/grub2/grub.cfg 5. cat /sys/kernel/mm/transparent_hugepage/enabled 6. init 6 7. cat /sys/kernel/mm/transparent_hugepage/enabled复制
实操步骤参考
-----实操步骤样例----
#1.查看
[root@yasrac01 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
#--若显示[always] madvise never，则说明透明大页开启。
#--若显示always madvise [never]，则说明透明大页关闭。
#2.修改
[root@yasrac01 ~]# vi /etc/default/grub
#3.查看
[root@yasrac01 ~]# cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never"
GRUB_DISABLE_RECOVERY="true"
#4.指令重新配置 grub.cfg
[root@yasrac01 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

3.7 关闭防火墙
以root用户身份在所有集群主机节点上执行如下命令：
systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld
复制3.8 创建用户及用户组
以root用户身份在所有集群主机节点上执行如下命令：
3.8.1 创建yashan用户及YASDBA组
groupadd YASDBA
useradd -d /home/yashan -G YASDBA -m yashan
echo "yashan" |passwd --stdin yashan
复制echo "yashan"是给yashan用户设置的密码为yashan，可以自定义密码。
3.9 配置共享存储
以root用户身份在所有集群主机节点上执行如下命令：
#获取共享磁盘scsi_id
[root@yasrac01 ~]# for i in {b..d}; do echo "sd$i" "`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i` "; done
sdb 36000c2998ba97b791417a905aa504ecc
sdc 36000c29bfaa52387f836611169fd042b
sdd 36000c29d1699cb57b26f05bdf88a622c
#根据获取id，按需填写，注意RESULT对应id和SYMLINK绑定的盘的关系
[root@yasrac02 ~]# cat /etc/udev/rules.d/yashan-device-rule.rules
KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29d1699cb57b26f05bdf88a622c", SYMLINK+="yas/data",OWNER="yashan", GROUP="YASDBA",MODE="0666"
KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29bfaa52387f836611169fd042b", SYMLINK+="yas/vote",OWNER="yashan", GROUP="YASDBA",MODE="0666"

#重新扫描设备
/sbin/udevadm trigger --type=devices --action=change
#在两个节点确认获取的id是否是一致的。
/usr/lib/udev/scsi_id --whitelisted --device=/dev/yas/data
/usr/lib/udev/scsi_id --whitelisted --device=/dev/yas/vote
/usr/lib/udev/scsi_id --whitelisted --device=/dev/yas/ycr
复制因为这里使用的是虚拟机，按照官方文档的配置磁阵的方式行不通，直接使用scsi_id命令找到磁盘wwid进行手动编辑绑定即可。
4. 安装部署集群
使用yahsan用户，在节点1执行即可。
#1.切换用户
su - yashan
#2.创建目录
mkdir install
将软件包上传到此目录/home/yashan/install
#3.解压软件
tar -zxvf yashandb-23.1.1.200-linux-x86_64.tar.gz
#4.生成配置文件
./bin/yasboot package ce gen --cluster yashandb -u yashan -p yashan --ip 192.168.33.111,192.168.33.112 --port 22 --install-path /home/yashan/yasdb_home --data-path /home/yashan/yasdb_data --begin-port 1688 --node 2 --data /dev/yas/data --vote /dev/yas/vote --ycr /dev/yas/ycr
#5.安装软件
./bin/yasboot package install -t hosts.toml -i yashandb-23.1.1.200-linux-x86_64.tar.gz
#6.部署集群
./bin/yasboot cluster deploy -t yashandb.toml --yfs-force-create
#7.设置环境变量
cd /home/yashan/yasdb_home/yashandb/23.1.1.200/conf/
cat yashandb.bashrc >> ~/.bashrc
source ~/.bashrc
#8.设置数据库sys用户密码，Cod-2023为密码，可自定义
yasboot cluster password set -n Cod-2023 -c yashandb
#9.登录数据库
yasql / as sysdba

5. 集群常用运维命令
使用ycsctl，需要先配置环境变量YASCS_HOME。
是ycsctl，不是yasctl
#在节点1环境变量(~/.bashrc)中添加
export YASCS_HOME=/home/yashan/ycs/ce-1-1
#在节点2环境变量(~/.bashrc)中添加
export YASCS_HOME=/home/yashan/ycs/ce-1-2
#在两个节点都执行，使环境变量生效
source ~/.bashrc
复制关闭实例
ycsctl stop instance #只会关闭当前节点的实例。
复制查看实例状态
yasctl status复制
查看集群参数（请注意这个AUTO_START=ALWAYS，后面重启集群会起到作用）
ycsctl show parameter复制
一个完整的集群关闭——>重启虚拟机——>启动集群步骤
#1.关闭数据库实例（在两个节点上分别执行）

#2.关闭ycs服务（在两个节点上分别执行）

#3.查看后台进程

#7.重启虚拟机（使用root用户）
init 6
#8.启动yasom（在节点1执行）
yasboot process yasom start -c yashandb
#9.启动yasagent（两个节点执行）
yasboot process yasagent start -c yashandb
#10.启动ycs，这里如果直接使用ycsctl start ycs会跳不出去运行界面，用nohup（在两个节点分别执行）
nohup ycsctl start ycs &
#11.检查集群状态，因为默认数据库会跟着一起来，这里不用再单独启动数据库了。参数AUTO_START控制的。
ycsctl status
复制6. 存疑
1.部署了两个节点，怎么有4个node的信息？
2.实例关闭需要约一分半，开启能即时完成。是否有参数调优的空间？
思考，gstack 收集堆栈信息，stop instance的过程在做什么？
