一：卸载的时候出现的错误： umount/dev/nb1 deviceis busy 解决：找到是什么进程使得他busy，用lsof /dev/nb1 . kill掉那个进程,然后重新umount即可。 二：GD2编译的时候出现的错误： Theusual way to define `LIBTOOL’ is to add `AC_PROG_LIBTOOL’ Libtoollibrary used but `LIBTOOL’ is undefined [Makefile.in]Error 1 解决：缺少编译安装的软件包。如：yuminstallautomake,libjpeg-devel,libpng-devel,freetype-devel,libtiff-devel,autoconf,gettext-devel,libtool 三：安装snmp的时候出现的错误： 1>/bin/sed:can’t read /usr/lib/libbeecrypt.la: No such file or directory libtool:link: `/usr/lib/libbeecrypt.la’ is not a valid libtool archive make[1]:*** [libnetsnmpmibs.la] Error 1 解决：以为缺少libbeecrypt.la，libbeecrypt.so等共享库，如：yum install libbeecrypt.la 2>/usr/bin/ld:cannot find -lelf 解决：ln-s /usr/lib/libelf.so.1 /usr/lib/libelf.so 3>/usr/bin/ld:can’tnot find -lselinux 解决：缺少libselinux和 libselinux-devel包，如：yum install libselinux 四：Rsync同步常见问题： 错误一： @ERROR:auth failed on module xxxxx rsync:connection unexpectedly closed (90 bytes read so far) rsyncerror: error in rsync protocol data stream (code 12) at io.c(150) 解决：这是因为密码设置错了，无法登入成功，检查一下rsync.pwd，看客服是否匹配。还有服务器端没启动rsync服务也会出现这种情况。 错误二： passwordfile must not be other-accessible continuingwithout password file Password: 解决：这是因为rsyncd.pwdrsyncd.sec的权限不对，应该设置为600。如：chmod 600 rsyncd.pwd 错误三： @ERROR:chroot failed rsync:connection unexpectedly closed (75 bytes read so far) rsyncerror: error in rsync protocol data stream (code 12) at io.c(150) 解决：这是因为你在rsync.conf 中设置的 path 路径不存在，要新建目录才能开启同步。 错误四： rsync:failed to connect to 218.107.243.2: No route to host (113) rsyncerror: error in socket IO (code 10) at clientserver.c(104)[receiver=2.6.9] 解决：对方没开机、防火墙阻挡、通过的网络上有防火墙阻挡，都有可能。关闭防火墙，其实就是把tcpudp 的873端口打开。 五：软件安装的时候常出现的问题： configure:error: …No recognized SSL/TLS toolkit detected #yum -y install openssl-devel configure:error: no acceptable cc found in $PATH yum-y install gcc-c++ configure:error: cannot find output from lex; giving up flex is not installed, installflex. yum-y install flex configure:error: xml2-config not found. Please check your libxml2 installation. yum-y install libxml2-devel configure:error: Cannot find OpenSSL’s yum-y install openssl-devel configure:error: Please reinstall the BZip2 distribution yum-y install bzip2-devel configure:error: Please reinstall the libcurl distribution - easy.h should be in/include/curl/ yum-y install curl-devel configure:error: libjpeg.(a|so) not found. yum-y install libjpeg-devel configure:error: libpng.(a|so) not found. yum-y install libpng-devel configure:error: freetype2 not found! yum-y install freetype-devel configure:error: Unable to locate gmp.h yum-y install gmp-devel configure:error: Cannot find pspell yum-y install aspell-devel libtool:link: cannot find the library `/usr/lib/libbeecrypt.la’ (librpmio.la:/usr/lib/libbeecrypt.la) 解决：缺少beecrypt包，如： http://sourceforge.net/projects/beecrypt下载beecrypt-4.1.2.tar.gz 然后运行如下命令： #tar-zxvf beecrypt-4.1.2.tar.gz #./configure #make #makeinstall
五.xauth: (stdin):1: bad display name "autotest:1" in "add"command
