记一次samba排错 Failed to start Samba SMB Daemon.

 

 记录一次服务出错排错的过程，很多新手出了点错不百度直接巴拉巴拉的问，一般老手根据经验可以给出一点建议，但是由于个体环境的差异并不适用，反而埋怨起来。这种真的无F**K可说，所以要培养自己的排错能力是很重要的，这里简单的抛砖引玉的举出个流程出来希望有所帮助。问问题之前善用各大搜索引擎以及博客论坛的搜索功能！

 

# systemctl status smb.service -l
â— smb.service - Samba SMB Daemon

//从网络上找的类似出错，源错误日志忘记保存

#systemctl start smb 出错

第一步：samba可以用testparm命令来测试smb.conf配置档的合法性

[root@longlong Templates]# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section "[homes]"
Processing section "[printers]"
Processing section "[print$]"
Loaded services file OK.
Server role: ROLE_STANDALONE

Press enter to see a dump of your service definitions

# Global parameters
[global]
    workgroup = SAMBA
    printcap name = cups
    security = USER
    idmap config * : backend = tdb
    cups options = raw


[homes]
    comment = Home Directories
    browseable = No
    inherit acls = Yes
    read only = No
    valid users = %S %D%w%S


[printers]
    comment = All Printers
    path = /var/tmp
    browseable = No
    printable = Yes
    create mask = 0600


[print$]
    comment = Printer Drivers
    path = /var/lib/samba/drivers
    create mask = 0664
    directory mask = 0775
    write list = root

 

可以看到配置文件没有错误，排除此错误！～


第二步：使用自带命令 输出samba日志

[root@longlong Templates]# smbd -F -S
smbd: relocation error: /usr/lib64/samba/libgse-samba4.so: symbol krb5_get_init_creds_opt_set_pac_request, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference

 

找出错误原因lib库出错

解决 yum -y install krb5-devel.x86_64 krb5-libs.x86_64

错误原因：进一步分析，查看yum源 发现是公网阿里云源，安装了新版本，系统库文件支持还是老版本所以运行出错

 

security=share在新版中已经被废弃了 所以最后贴个4以上samba新版本

samba-4.6.2-8.el7.x86_64

建立匿名用户Linux和windows共享目录的配置文件：

[global]
        workgroup = SAMBA
        security = user

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw
        map to guest = Bad User
