配置本地yum源,之后使用yum安装rpm包
yum install msodbcsql-13.1.9.2-1.x86_64.rpm
yum install msodbcsql17-17.4.2.1-1.x86_64.rpm
yum install mssql-server-14.0.3238.1-19.x86_64.rpm
yum install mssql-tools-17.4.1.1-1.x86_64.rpm

sqlcmd配置
sqlcmd登陆时报如下错误
Microsoft ODBC Driver 17 for SQL Server : TCP Provider: Error code 0x2746
因系统进行安全加固,对ssl进行了升级,Sql Server和SSMS依赖的SSL是1.0版本的,由于版本不一致造成无法链接
解决方案如下:
# 先停止MSSQL
sudo systemctl stop mssql-server
# 编辑服务配置
sudo systemctl edit mssql-server
# 在打开的编辑器中输入
[Service]
Environment="LD_LIBRARY_PATH=/opt/mssql/lib"
#输入完保存
# 给MSSQL创建指向SSL1.0的链接
sudo ln -s /usr/lib64/libssl.so.1.0.2k /opt/mssql/lib/libssl.so
sudo ln -s /usr/lib64/libcrypto.so.1.0.2k /opt/mssql/lib/libcrypto.so
数据目录配置
修改数据库数据文件及备份文件位置
mkdir -p /mssql/data
mkdir -p /backup
chown -R mssql:mssql /mssql/
chown -R mssql:mssql /backup/
/opt/mssql/bin/mssql-conf set filelocation.defaultdatadir /mssql/data
/opt/mssql/bin/mssql-conf set filelocation.defaultlogdir /mssql/data
/opt/mssql/bin/mssql-conf set filelocation.defaultbackupdir /backup
/opt/mssql/bin/mssql-conf set filelocation.defaultdumpdir /backup
设置排序规则
修改数据库排序规则
/opt/mssql/bin/mssql-conf set-collation
Latin1_General_CI_AS
备份恢复
数据备份
创建备份脚本
#!/bin/bash
source /etc/profile
# 以下是配置信息
user=sa
passwd=Password01
back_path=/backup
db_list="[Test-clear] [Freem]"
back_time=`date +%Y%m%d`
for db_name in $db_list
do
echo "==============开始备份数据库[$db_name]=============" >> log$back_time.log
back_filename=$back_path/$db_name$back_time
sqlcmd -S localhost -U $user -P $passwd -d master -Q "BACKUP DATABASE $db_name to disk='$back_filename.bak'"
if [ -e $back_filename.bak ];then
echo "==============数据库[$db_name] 备份成功!=============" >> log$back_time.log
else
echo "==============数据库[$db_name] 备份失败!=============" >> log$back_time.log
fi
done
设置定时任务
crontab -e
0 23 * * * /root/scripts/back.sh # 每天晚上23点执行
备份还原
获取数据库逻辑名
1> restore filelistonly from disk = '/tmp/Test-clear.bak'
2> go
数据库还原,库名包含特殊字符,需要使用中括号包围
RESTORE DATABASE [TaskProcess-clear] FROM DISK = '/tmp/TaskProcess-clear.bak'
WITH MOVE 'TaskProcess-clear' TO '/mssql/data/TaskProcess-clear.mdf',
MOVE 'TaskProcess-clear_log' TO '/mssql/data/TaskProcess-clear_log.ldf'
GO
权限分配
登录名只有登进数据库的功能 ,登录名可以映射用户名, 这样就有了相应的权限
本方案将创建两个用户并赋予数据库权限,将两个用户名映射到登录名,登录后可以操作两个数据库
创建登录名
create login aps with password='Aps2022'
go
创建用户名Test-clear
use [Test-clear]
go
create user Test-clear for login aps
go
# 赋予数据库权限
exec sp_addrolemember 'db_owner', 'Test-clear'
go
# 设置用户默认schema
alter user Freemwith default_schema=Test-clear;
go
创建用户名Freem
use Freem
go
create user Freem for login aps
go
# 赋予数据库权限
exec sp_addrolemember 'db_owner', 'Freem'
go
设置用户默认schema
alter user Freemwith default_schema=Freem;
go
日常操作
sqlcmd登录
# sqlcmd -U sa -P Test2016
查询数据库版本
1> select @@version
2> go
