升级bind带来的小故障

bind升级后,在启动时出错,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

查看bind-libs包的文件:

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

再次确认文件:

#　whereis libbind9.so.50

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

# whereis liblwres.so.50

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

看似没错~

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

看到了没,一开始看到的都没错,可到最后发现原来此路不通~

解决方法很简单:删除错误的软链接,然后重新建立一个正确的软链接.

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

-_-这种错误也会犯?
