CentOS 7 samba共享

背景
原计划基于Windows(主)+Linux(从)搭建SQL server主从同步,基于共享同一个目录而尝试用samba
#测试之后发现无法实现,因为Linux和Windows存放数据的文件夹不同,双发无法识别(个人想法)

 

环境
[root@node1 ~]# lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID:    CentOS
Description:    CentOS Linux release 7.5.1804 (Core)
Release:    7.5.1804
Codename:    Core

 

查看是否安装
rpm -qa samba

安装
yum -y install samba samba-client
samba配置
cd /etc/samba/
mv smb.conf smb.conf.origin
新建smb.conf
vim smb.conf

[global]
        workgroup = WORKGROUP
        server string = Ted Samba Server %v
        netbios name = TedSamba
        security = user
        map to guest = Bad User
        passdb backend = tdbsam

[FileShare]
        comment = share some files
        path = /smb/fileshare
        public = yes
        writeable = yes
        create mask = 0644
        directory mask = 0755

[WebDev]
        comment = project development directory
        path = /smb/webdev
        valid users = ted
        write list = ted
        printable = no
        create mask = 0644
        directory mask = 0755

注释：
workgroup 项应与 Windows 主机保持一致，这里是WORKGROUP
security、map to guest项设置为允许匿名用户访问
再下面有两个section，实际为两个目录，section名就是目录名（映射到Windows上可以看见）。
第一个目录名是FileShare，匿名、公开、可写
第二个目录吗是WebDev，限定ted用户访问
默认文件属性644/755（不然的话，Windows上在这个目录下新建的文件会有“可执行”属性）

创建用户
[root@base samba]# groupadd co3
[root@base samba]# useradd ted -g co3 -s /sbin/nologin
[root@base samba]# smbpasswd -a ted
New SMB password:
Retype new SMB password:
Added user ted.
[root@base samba]#
注意这里smbpasswd将使用系统用户。设置密码为1
创建共享目录
[root@base samba]# mkdir -p /smb/{fileshare,webdev}
[root@base samba]# chown nobody:nobody /smb/fileshare/
[root@base samba]# chown ted:co3 /smb/webdev/
注意设置属性，不然访问不了。
启动Samba服务，设置开机启动
[root@base samba]# systemctl start smb
[root@base samba]# systemctl enable smb
Created symlink from /etc/systemd/system/multi-user.target.wants/smb.service to /usr/lib/systemd/system/smb.service.
[root@base samba]#
开放端口
[root@base samba]# firewall-cmd --permanent --add-port=139/tcp
success
[root@base samba]# firewall-cmd --permanent --add-port=445/tcp
success
[root@base samba]# systemctl restart firewalld
[root@base samba]#
或者直接把防火墙关了也行。

注意:腾讯云后台有个安全组也要打开响应的端口.

 

使用本机测试
可以使用testparm测试samba配置是否正确
[root@base samba]# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

root用户的话，不用密码可直接查看samba服务器情况
[root@base samba]# smbclient -L localhost
Enter root's password:
