1.安装ceph环境（略）
2.安装iscsi 启动器及目标器（略）
修改iscsi启动器地址为ceph集群块设备target，然后扫描并登陆启动器，挂载块设备
这里最好使用多路径（安装multipath服务），然后将块设备路径挂载在客户端（即sqlserver安装节点上、/mnt/sqlserver）
1）查看多路径，
[root@client-152 ~]# multipath -ll
36001405f091d90da55e450e8dd2d4a54 dm-0 ORCADT ,OrcaBlockDevice
size=1.0T features='1 queue_if_no_path' hwhandler='1 alua' wp=rw
|-+- policy='queue-length 0' prio=130 status=active
| `- 36:0:0:0 sdb 8:16 active ready running
|-+- policy='queue-length 0' prio=10 status=enabled
| `- 37:0:0:0 sdd 8:48 active ready running
`-+- policy='queue-length 0' prio=10 status=enabled
`- 35:0:0:0 sdc 8:32 active ready running
2）查看块设备映射磁盘
[root@client-152 ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 200M 0 part /boot/efi
├─sda2 8:2 0 500M 0 part /boot
├─sda3 8:3 0 7.8G 0 part [SWAP]
└─sda4 8:4 0 923G 0 part /
sdb 8:16 0 1T 0 disk
└─36001405f091d90da55e450e8dd2d4a54 253:0 0 1T 0 mpath
sdc 8:32 0 1T 0 disk
└─36001405f091d90da55e450e8dd2d4a54 253:0 0 1T 0 mpath
sdd 8:48 0 1T 0 disk
└─36001405f091d90da55e450e8dd2d4a54 253:0 0 1T 0 mpath
3）创建挂载目录，格式化映射磁盘（此过程时间较长，至于格式化什么样文件系统 ，根据自己喜好）
[root@client-152 ~]# mkdir /mnt/sqlserver
[root@client-152 ~]# chmod 777 /mnt/sqlserver
[root@client-152 ~]# mkfs.xfs /dev/mapper/36001405f091d90da55e450e8dd2d4a54

3.安装sql server服务
http://www.linuxidc.com/Linux/2017-12/149609.htm
系统需求：
CentOS7.3以上，我目前用的是CenOS7.4
服务器至少3.25GB内存
好像对CPU没有什么要求，我在虚拟机中配置的CPU为一核
一、安装 SQL Server
1、下载 Microsoft SQL Server Red Hat 存储库配置文件：
[root@CentOS7 ~]# curl -o /etc/yum.repos.d/mssql-server.repo https://packages.microsoft.com/config/rhel/7/mssql-server-2017.repo
2、运行以下命令，安装 SQL Server：
[root@CentOS7 ~]# yum update
[
[root@CentOS7 ~]# yum install -y mssql-server
3、运行包安装完成后mssql-conf 安装并按照提示操作以设置 SA 密码，并选择你的版本。
root@CentOS7 ~]# /opt/mssql/bin/mssql-conf setup
选择 SQL Server 的一个版本:
1) Evaluation (免费，无生产许可，180 天限制)
2) Developer (免费，无生产许可)
3) Express (免费)
4) Web (付费版)
5) Standard (付费版)
6) Enterprise (付费版)
7) Enterprise Core (付费版)
8) 我通过零售渠道购买了许可证并具有要输入的产品密钥。
可在以下位置找到有关版本的详细信息:
https://go.microsoft.com/fwlink/?LinkId=852748&clcid=0x804
使用此软件的付费版本需要通过以下途径获取单独授权
M
Microsoft 批量许可计划。
选择付费版本即表示你具有适用的
要安装和运行此软件的就地许可证数量。
输入版本(1-8): 1
为了测试该版本数据库的全部功能，我这里选择的是 1Evaluation版本，如果不是为了测试的话，可以选择2Developer 或者 3 Express这二个版本。如果你是购买了正式版序列号的用户，可以根据情况选择4-8的各个版本。
然后系统会提示你是否同意许可条款，当然输入yes了
可以在以下位置找到此产品的许可条款:
/
/usr/share/doc/mssql-server 或从以下位置下载:
https://go.microsoft.com/fwlink/?LinkId=855864&clcid=0x804
可以从以下位置查看隐私声明:
https://go.microsoft.com/fwlink/?LinkId=853010&clcid=0x804
接受此许可条款吗? [Yes/No]:yes
下面是选择语言：
选择 SQL Server 的语言:
(
(1) English
(
(2) Deutsch
(
(3) Español
(
(4) Français
(
(5) Italiano
(
(6) 日本語
(
(7) 한국어
(
(8) Português
(
(9) Русский
(
(10) 中文 – 简体
(
(11) 中文 （繁体）
输入选项 1-11:10
这个不用说了吧，选择10
接下来设置SQL密码，输入二次。
请确保为 SA 帐户指定强密码（最少 8 个字符，包括大写和小写字母、十进制数字和/或非字母数字符号）：
输入 SQL Server 系统管理员密码:
（注：这里输入密码时候如果不是很确认最好复制下来粘贴进去！）
确认 SQL Server 系统管理员密码:
在安装的最后，系统会提示如下：
正在配置 SQL Server...
C
Created symlink from /etc/systemd/system/multi-user.target.wants/mssql-server.service to /usr/lib/systemd/system/mssql-server.service.
安装程序已成功完成。SQL Server 正在启动。
4、配置完成后，请验证服务是否正在运行：
[root@CentOS7 ~]# systemctl status mssql-server
● mssql-server.service - Microsoft SQL Server Database Engine
Loaded: loaded (/usr/lib/systemd/system/mssql-server.service; enabled; vendor preset: disabled)
Active: active (running) since 四 2017-10-05 14:19:18 CST; 21s ago
Docs: https://docs.microsoft.com/en-us/sql/linux
Main PID: 1208 (sqlservr)
CGroup: /system.slice/mssql-server.service
├─1208 /opt/mssql/bin/sqlservr
└─1228 /opt/mssql/bin/sqlservr
.
............
（以下进行省略）
如果运行结果如上（●正常是绿颜色的）就是服务正常运行了。
5、若要允许远程连接，请打开防火墙上的 SQL Server 端口。
默认的 SQL Server 端口为 TCP 1433。 如果你使用FirewallD防火墙，可以使用以下命令添加规则：
[root@CentOS7 ~]# firewall-cmd --zone=public --add-port=1433/tcp --permanent
success
[root@CentOS7 ~]# firewall-cmd --reload
success
当然如果你的服务器前端是有防火墙进行保护的，也可以不用运行上述命令，而是直接将系统的防火墙关闭。使用如下命令关闭firewallD防火墙并设置为开机不自动启动：
[root@CentOS7 ~]# systemctl stop firewalld
[
[root@CentOS7 ~]# systemctl disable firewalld
R
Removed symlink /etc/systemd/system/dbus-org.Fedoraproject.FirewallD1.service.
R
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
以上就完成了SQL Server 2017的安装
二、安装 SQL Server 命令行工具
以下步骤安装 SQL Server 命令行工具： sqlcmd和bcp。
1、下载安装源。
[root@CentOS7 ~]# curl -o /etc/yum.repos.d/msprod.repo https://packages.microsoft.com/config/rhel/7/prod.repo
2、安装mssql 工具与 unixODBC 开发人员包
[root@CentOS7 ~]# yum update
[
[root@CentOS7 ~]# yum install -y mssql-tools unixODBC-devel
安装之前系统会提示你必须同意相关许可，注意：需要输入大写的YES
The license terms for this product can be downloaded from
https://aka.ms/odbc131eula and found in
/
/usr/share/doc/msodbcsql/LICENSE.TXT . By entering 'YES',
y
you indicate that you accept the license terms.

D

.
.............
（以下进行省略）
3、添加/opt/mssql-tools/bin/到环境变量
[root@CentOS7 ~]# echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile
[
[root@CentOS7 ~]# echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
[
[root@CentOS7 ~]# source ~/.bashrc
配置sql server
https://blog.51cto.com/ultrasql/2152021?source=dra
这里要注意的是：
1）创建默认数据及日志路径，并修改合适权限
[root@client-152 yum.repos.d]# mkdir /mnt/sqlserver/data
[root@client-152 yum.repos.d]# mkdir /mnt/sqlserver/log
[root@client-152 yum.repos.d]# mkdir /mnt/sqlserver/backup
[root@client-152 yum.repos.d]# mkdir /mnt/sqlserver/audit
[root@client-152 yum.repos.d]# chown mssql:mssql -R /mnt/sqlserver/
[root@client-152 yum.repos.d]# ll /mnt/sqlserver/
total 0
drwxr-xr-x 2 mssql mssql 6 Mar 27 15:20 data
drwxr-xr-x 2 mssql mssql 6 Mar 27 15:20 log
[root@client-152 yum.repos.d]# chmod 777 -R /mnt/sqlserver
[root@client-152 yum.repos.d]# ll /mnt/sqlserver/
total 0
drwxrwxrwx 2 mssql mssql 6 Mar 27 15:20 data
drwxrwxrwx 2 mssql mssql 6 Mar 27 15:20 log
2）设置存储路径
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.defaultdatadir /mnt/sqlserver/data/
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.defaultlogdir /mnt/sqlserver/log/
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
[root@client-152 yum.repos.d]#
3）创建master数据库数据及log文件，（注，这里是文件，不是目录）
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.masterdatafile /mnt/sqlserver/master.mdf
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.masterlogfile /mnt/sqlserver/mastlog.ldf
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
修改默认错误日志目录位置
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.errorlogfile /mnt/sqlserver/log/errorlog
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
修改默认备份目录位置
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set filelocation.defaultbackupdir /mnt/sqlserver/backup
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
修改审计日志目录
[root@client-152 yum.repos.d]# /opt/mssql/bin/mssql-conf set telemetry.userrequestedlocalauditdirectory /mnt/sqlserver/audit
SQL Server needs to be restarted in order to apply this setting. Please run
'systemctl restart mssql-server.service'.
【或直接修改配置文件如下
[root@client-152 mssql]# cat mssql.conf
[EULA]
accepteula = Y
[filelocation]
defaultdatadir = /mnt/sqlserver/data/
defaultlogdir = /mnt/sqlserver/log/
masterdatafile = /mnt/sqlserver/master.mdf
masterlogfile = /mnt/sqlserver/mastlog.ldf
errorlogfile = /mnt/sqlserver/log/errorlog
defaultbackupdir = /mnt/sqlserver/backup
[telemetry]
userrequestedlocalauditdirectory = /mnt/sqlserver/audit
】
4）停止数据库服务，移动当前数据文件到创建路径后启动
[root@client-152 yum.repos.d]# systemctl stop mssql-server
[root@client-152 yum.repos.d]# systemctl status mssql-server

好了 ，到这里主要的数据存储目录都已经挂载至ceph集群了，剩下的核心转储等如有需要自行配置
5）使用数据库
Password1
[root@client-152 log]# sqlcmd -S 127.0.0.1 -U SA -P Password1
1> create database testttt
2> go
1> use testttt
2> go
Changed database context to 'testttt'.
1> select name from sys.databases
2> go
name
--------------------------------------------------------------------------------------------------------------------------------
master
tempdb
model
msdb
testttt
(5 rows affected)
1> create table emp(id int,name nvarchar(50))
2> go
1> insert into emp values(1001,'jerry') ;insert into emp values(1002,'loki')
2> go
(1 rows affected)
(1 rows affected)
1> select * from emp;
2> go
id name
----------- --------------------------------------------------
1001 jerry
1002 loki

1>exec sp_tables （查询所有表）
存储，批量创建脚本，注（其中批量创建库会失败，有大佬知道的话请不吝指教）
