丐版sqlserver集群
之前试过docker的,k8s的,然后发现,还是最朴素的是最简单的,希望有大佬能够汉化,他妈的,那些英文看得人要发癫啊。
前置准备,参照丐版pxc集群:
https://www.cnblogs.com/zwnfdswww/p/18112077
如果不关防火墙:
打开对应的端口即可:
sudo firewall-cmd --zone=public --add-port=1433/tcp --permanent
sudo firewall-cmd --reload
sudo hostnamectl set-hostname m191
sudo hostnamectl set-hostname m192
sudo hostnamectl set-hostname m193
bash
vim /etc/hosts
10.1.161.29 m191
10.1.161.31 m192
10.1.161.32 m193
sudo curl -o /etc/yum.repos.d/mssql-server.repo https://packages.microsoft.com/config/rhel/7/mssql-server-2019.repo
sudo yum install -y mssql-server
sudo /opt/mssql/bin/mssql-conf setup
设置密码:
Citygis@1613
systemctl status mssql-server
yum install mssql-server-agent
/opt/mssql/bin/mssql-conf set sqlagent.enabled true
systemctl restart mssql-server.service
sudo curl -o /etc/yum.repos.d/msprod.repo https://packages.microsoft.com/config/rhel/7/prod.repo
sudo yum remove unixODBC-utf16 unixODBC-utf16-devel
sudo yum install -y mssql-tools unixODBC-devel
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile
echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
source ~/.bashrc
sqlcmd -S 10.1.161.32 -U SA -P 'Citygis@1613'
CREATE DATABASE TestDB
SELECT Name from sys.Databases
GO
USE TestDB
CREATE TABLE Inventory (id INT, name NVARCHAR(50), quantity INT)
INSERT INTO Inventory VALUES (1, 'banana', 150); INSERT INTO Inventory VALUES (2, 'orange', 154);
GO
SELECT * FROM Inventory WHERE quantity > 152;
GO
QUIT
需要几台服务器,重复安装即可
测试:
navicat连一下
10.1.161.29,1433
SA Citygis@1613
如果没有驱动,去navicat目录下安装sqlncli_x64即可
sql(all)
将 SA 帐户禁用:
ALTER LOGIN SA DISABLE;
CREATE LOGIN Citygis@1613 WITH PASSWORD = 'Citygis@1613';
ALTER SERVER ROLE sysadmin ADD MEMBER Citygis@1613;
重要:新用户登录
ALTER LOGIN SA DISABLE;
Bash(all):
sudo /opt/mssql/bin/mssql-conf set hadr.hadrenabled 1
sudo systemctl restart mssql-server
Bash(all)
yum install -y mssql-server-ha
yum info mssql-server-ha
Sql(all):
ALTER EVENT SESSION AlwaysOn_health ON SERVER WITH (STARTUP_STATE=ON);
GO
Sql(all):
CREATE LOGIN dbm_login WITH PASSWORD = '1111.aaa';
CREATE USER dbm_user FOR LOGIN dbm_login;
第一个是登录用户,第二个是执行用户
Sql(主):
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1111.aaa';
CREATE CERTIFICATE dbm_certificate WITH SUBJECT = 'dbm';
BACKUP CERTIFICATE dbm_certificate
TO FILE = '/var/opt/mssql/data/dbm_certificate.cer'
WITH PRIVATE KEY (
FILE = '/var/opt/mssql/data/dbm_certificate.pvk',
ENCRYPTION BY PASSWORD = '1111.aaa'
);
ls /var/opt/mssql/data
看下文件有没有生成
Bash(主):
cd /var/opt/mssql/data/
scp dbm_certificate.* 10.1.161.31:/var/opt/mssql/data/
scp dbm_certificate.* 10.1.161.32:/var/opt/mssql/data/
Bash(从);
cd /var/opt/mssql/data/
chown mssql.mssql dbm_certificate.*
Sql(从):
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1111.aaa';
CREATE CERTIFICATE dbm_certificate
AUTHORIZATION dbm_user
FROM FILE = '/var/opt/mssql/data/dbm_certificate.cer'
WITH PRIVATE KEY (
FILE = '/var/opt/mssql/data/dbm_certificate.pvk',
DECRYPTION BY PASSWORD = '1111.aaa'
);
Sql(all);
CREATE ENDPOINT [Hadr_endpoint]
AS TCP (LISTENER_PORT = 5022)
FOR DATABASE_MIRRORING (
ROLE = ALL,
AUTHENTICATION = CERTIFICATE dbm_certificate,
ENCRYPTION = REQUIRED ALGORITHM AES
);
ALTER ENDPOINT [Hadr_endpoint] STATE = STARTED;
GRANT CONNECT ON ENDPOINT::[Hadr_endpoint] TO [dbm_login];
sudo firewall-cmd --zone=public --add-port=5022/tcp --permanent
sudo firewall-cmd --reload
Sql(all);
select @@SERVERNAME;
Sql(主):
CREATE AVAILABILITY GROUP [ag1]
WITH (DB_FAILOVER = ON, CLUSTER_TYPE = EXTERNAL)
FOR REPLICA ON
N'm191'
WITH (
ENDPOINT_URL = N'tcp://m191:5022',
AVAILABILITY_MODE = SYNCHRONOUS_COMMIT,
FAILOVER_MODE = EXTERNAL,
SEEDING_MODE = AUTOMATIC,
SECONDARY_ROLE (ALLOW_CONNECTIONS = ALL)
),

);
ALTER AVAILABILITY GROUP [ag1] GRANT CREATE ANY DATABASE;
Sql(从):
ALTER AVAILABILITY GROUP [ag1] JOIN WITH (CLUSTER_TYPE = EXTERNAL);
ALTER AVAILABILITY GROUP [ag1] GRANT CREATE ANY DATABASE
(如果报错,可能是hosts文件里面主机名对应ip错了)
测试一下:
Sql(主):
CREATE DATABASE [db1];
ALTER DATABASE [db1] SET RECOVERY FULL;
BACKUP DATABASE [db1]
TO DISK = N'/var/opt/mssql/data/db1.bak';
ALTER AVAILABILITY GROUP [AG1] ADD DATABASE [db1];
从节点查一下。
集群完成。
DROP AVAILABILITY GROUP group_name
可选:
Bash(all)
sudo yum install subscription-manager
用户名和密码去redhat官网申请
vi /etc/rhsm/rhsm.conf
Set to 1 to disable certificate validation:
insecure = 1
sudo subscription-manager register
sudo subscription-manager list --available
sudo subscription-manager attach --pool=
其中,“PoolId”是上一步中高可用性订阅的池 ID 。
subscription-manager repos --list
选一个高可用相关的软件仓库
sudo subscription-manager repos --enable=rhel-ha-for-rhel-7-server-rpms
(备用:sudo subscription-manager repos --enable=rhel-atomic-7-cdk-3.3-rpms)
如果系统自带了有,可以不执行上面的命令
Bash(all):
yum install pacemaker pcs resource-agents corosync fence-agents-all -y
Bash(all):
passwd hacluster (这里密码一定要设置成一样的,我这设置的是123456.com)
Bash(all):
sudo systemctl enable pcsd
sudo systemctl start pcsd
sudo systemctl enable pacemaker

firewall-cmd --zone=public --add-port=2224/tcp --permanent
firewall-cmd --zone=public --add-port=3121/tcp –permanent
firewall-cmd --zone=public --add-port=5405/udp --permanent
firewall-cmd --reload
Bash(all):
sudo pcs cluster destroy
sudo systemctl enable pacemaker
Bash(主):
sudo pcs cluster auth m191 m192 m193 -u hacluster -p 123456.com
sudo pcs cluster setup --name AG1 m191 m192 m193
chown -R hacluster.haclient /var/log/cluster

pcs cluster enable –all
pcs cluster status
ps aux | grep pacemaker

pcs status corosync
crm_verify -L -V
(all):
pcs property set stonith-enabled=false
pcs property set no-quorum-policy=ignore
Bash(all):
sudo pcs property set stonith-enabled=false
Bash(all):
yum install mssql-server-ha –y
sudo systemctl restart mssql-server
Sql(all):
USE [master]
GO
CREATE LOGIN [pacemakerLogin] with PASSWORD= N'1111.aaa';
ALTER SERVER ROLE [sysadmin] ADD MEMBER [pacemakerLogin]
Bash(all):
sudo echo 'pacemakerLogin' >> ~/pacemaker-passwd
sudo echo '1111.aaa' >> ~/pacemaker-passwd
sudo mv ~/pacemaker-passwd /var/opt/mssql/secrets/passwd
sudo chown root:root /var/opt/mssql/secrets/passwd
sudo chmod 400 /var/opt/mssql/secrets/passwd
Bash(主)
重要,ip记得改
sudo pcs resource create ag_cluster ocf:mssql:ag ag_name=AG1 meta failure-timeout=60s master notify=true
sudo pcs resource create virtualip ocf
