【要求】

实现一键安装并配置samba服务，执行该脚本时需要带一个共享的路径，它是共享的目录，目录若存在，需自动创建samba。要求，任何人都可以访问，并且不需要密码，并且是只读的。

vi /opt/samba.sh
#!/bin/bash
if [ "$#" -ne 1 ]
thenecho "运行脚本格式为：$0 /dir/"
exit 1
elseif ! echo $1 |grep -q '^/.*'thenecho "请提供一个绝对路径！"exit 0fi
fiif ! rpm -q samba >/dev/null
thenecho "将要安装samba"sleep 1yum -y install sambaif [ $? -ne 0 ]thenecho "samba 安装失败"exit 1fi
fidirconf="/etc/samba/smb.conf"
cat >> $dirconf << EOF
[global]workgroup = workgroupsecurity = usermap to guest = bad user
[share]comment= share allpath = $1browseable = yespublic = yeswritable = no
EOFif [ ! -d $1 ]
thenmkdir -p $1
fichmod 777 $1
chown nobody:nobody $1
echo "www.51xit.top" > $1/51xit.txtsystemctl start smb
if [ $? -ne 0 ]
thenecho "samba服务启动失败，请检查配置文件是否正常"
elseecho "samba服务启动正常"
fi
chmod +x /opt/samba.sh

【测试】

/opt/samba.sh  /opt/samba/
/opt/samba
目录是绝对路径！
samba-4.8.3-4.el7.x86_64
samba已安装！
