Linux uses samba to realize file sharing

ready:

①Two Centos7.6

192.168.1.67	client side
192.168.1.88	server side

②Stop the firewall and selinux, turn off the firewall and start on by default

systemctl  stop firewalld

systemctl  disable  firewalld

# 查看selinux运行状态
getenforce

# 修改selinux状态
vim /etc/selinux/config

1. Install samba on the server and samba-client on the client

yum install  samba  samba-client  -y

systemctl  start  smb  nmb

# 查看samba运行状态
netstat -antp

2. Create a new linux user without login permission, add it as a samba user and set a password

# 创建一个不能登录的linux用户
useradd  -s /sbin/nologin  wenlong

# 将linux系统用户设为samba用户，并按照提示设置密码
pdbedit   -a  wenlong

# //读取当前samba用户列表
pdbedit  -L

Three, view samba shared files, the default is wenlong's home directory

# 在客户端192.168.1.67查看wenlong用户的共享信息，默认是wenlong的家目录
smbclient -U  wenlong  -L  //192.168.1.88

# 在客户端client登录查看共享文件
smbclient -U  wenlong    //192.168.1.88/wenlong

Four, custom shared space, test

①Edit the samba configuration file smb.conf on the server side, add the sambatest block code below, and the node name sambatest

vim /etc/samba/smb.conf

[sambatest]
        # 共享目录是根目录下的test文件夹
        path = /test
        public = yes
        # 是否可见
        browseable = yes
        guest ok = yes
        writable = yes

②Create the shared directory marked by path in the configuration file on the server side, and grant permissions

# 创建共享测试文件夹test
mkdir  /test

# 修改权限，777给所有用户提供读写执行权。1粘着位，表示仅允许删除或重命名自己的文件
# 这里涉及到SUID、SGID、SBIT,代表文件包括/etc/passwd,/usr/bin/locate,和下边这种情况
# SUID用4表示，SGID用2表示，SBIT用1表示
# 备注：大多数情况不需要修改，除非特殊情况
chmod  1777  /test/

③Restart the samba service on the server side and test whether the configuration file modification is correct

# 修改配置文件后，重启smb服务
systemctl  restart smb  nmb

# 查看配置文件是否正确
testparm

④ The client client looks at the shared folder and sees the shared folder named sambatest

# 再次查看wenlong共享的文件
smbclient -U  wenlong  -L  //192.168.1.88

⑤The client client logs in to the shared node sambatest, and can perform samba's own operations

# 在client端使用wenlong从共享文件节点sambatest登录
smbclient -U  wenlong    //192.168.1.88/sambatest

Five, mount the share to the local directory

①Create a new mount point clienttest on the client side, and create clienttest in the root directory

# 创建挂载点
mkdir  /clienttest

②Create a temporary mount and view the mount situation

# 临时挂载
mount  -t cifs  -o username=wenlong,password=123456  //192.168.1.88/sambatest   /clienttest

# 查看挂载情况
df -h

③ Permanently mount, edit the fstab file on the client side, restart the server to view the mount

vim /etc/fstab

//192.168.1.88/sambatest  /clienttest  cifs  defaults,username=wenlong,password=123456   0  0

df  -h

④Check the shared folder mounted on the client side and create a new test file

# 进入挂载点
cd /clienttest/

# 新建测试文件aaa
vim  aaa

# 查看当前文件列表
ll

# 查看aaa文件内容
cat  aaa

⑤View the test file on the server server

cd /test/

ll

cat  aaa
