更新bind帶來的小故障

bind更新後,在啟動時出錯,如下:

Error in named configuration:

/usr/sbin/named-checkconf: error while loading shared libraries: libbind9.so.50: cannot open shared object file: No such file or directory

# nslookup www.g.cn

nslookup: error while loading shared libraries: liblwres.so.50: cannot open shared object file: No such file or directory

檢視bind-libs包的檔案:

rpm -q --list bind-libs

/usr/lib64/libbind9.so.50

/usr/lib64/libbind9.so.50.0.3

/usr/lib64/libdns.so.50

/usr/lib64/libdns.so.50.2.0

/usr/lib64/libisc.so.50

/usr/lib64/libisc.so.50.1.1

/usr/lib64/libisccc.so.50

/usr/lib64/libisccc.so.50.0.0

/usr/lib64/libisccfg.so.50

/usr/lib64/libisccfg.so.50.0.0

/usr/lib64/liblwres.so.50

/usr/lib64/liblwres.so.50.0.2

再次确認檔案:

#　whereis libbind9.so.50

libbind9.so: /usr/lib64/libbind9.so.50

# whereis liblwres.so.50

liblwres.so: /usr/lib64/liblwres.so.50

看似沒錯~

再看下~

# ll /usr/lib64/|grep libbin

lrwxrwxrwx.  1 root root       18 2009-07-04 11:54 libbind9.so.50 -> libbind9.so.50.2.0

-rwxr-xr-x.  1 root root    41808 2009-06-24 22:58 libbind9.so.50.0.3

# ll /usr/lib64/|grep liblw

lrwxrwxrwx.  1 root root       18 2009-07-04 11:54 liblwres.so.50 -> liblwres.so.50.2.0

-rwxr-xr-x.  1 root root    73336 2009-06-24 22:58 liblwres.so.50.0.2

看到了沒,一開始看到的都沒錯,可到最後發現原來此路不通~

解決方法很簡單:删除錯誤的軟連結,然後重建立立一個正确的軟連結.

rm -f /usr/lib64/libbind9.so.50

rm -f /usr/lib64/liblwres.so.50

ln -s /usr/lib64/libbind9.so.50.0.3 /usr/lib64/libbind9.so.50

ln -s /usr/lib64/liblwres.so.50.0.2 /usr/lib64/liblwres.so.50

-_-這種錯誤也會犯?
