記一次samba排錯 Failed to start Samba SMB Daemon.

 

 記錄一次服務出錯排錯的過程，不少新手出了點錯不百度直接巴拉巴拉的問，通常老手根據經驗能夠給出一點建議，可是因爲個體環境的差別並不適用，反而埋怨起來。這種真的無F**K可說，因此要培養本身的排錯能力是很重要的，這裏簡單的拋磚引玉的舉出個流程出來但願有所幫助。問問題以前善用各大搜索引擎以及博客論壇的搜索功能！

 

# systemctl status smb.service -l

//從網絡上找的相似出錯，源錯誤日誌忘記保存

#systemctl start smb 出錯

第一步：samba能夠用testparm命令來測試smb.conf配置檔的合法性

[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

# 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

 

能夠看到配置文件沒有錯誤，排除此錯誤！～


第二步：使用自帶命令 輸出samba日誌

[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

 

找出錯誤緣由lib庫出錯

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

錯誤緣由：進一步分析，查看yum源 發現是公網阿里雲源，安裝了新版本，系統庫文件支持仍是老版本因此運行出錯

 

security=share在新版中已經被廢棄了 因此最後貼個4以上samba新版本

samba-4.6.2-8.el7.x86_64

創建匿名用戶Linux和windows共享目錄的配置文件：

[global]
        workgroup = SAMBA
        security = user

        passdb backend = tdbsam

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