This article focuses on "what are the common mistakes in the linux system". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn what are the common mistakes in the linux system.

One: the error occurred when uninstalling:

Umount / dev/nb1

Device is busy

Solution: find out what process makes him busy, using lsof / dev/nb1. Kill drop that process, and then re-umount it.

Second: errors in the compilation of GD2:

The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'

Libtool library used but `LIBTOOL' is undefined

[Makefile.in] Error 1

Fix: lack of compiled and installed packages. Such as: yum install automake,libjpeg-devel,libpng-devel,freetype-devel,libtiff-devel,autoconf,gettext-devel,libtool

Third, the error occurred when installing snmp:

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

Solution: thinking that shared libraries such as libbeecrypt.la and libbeecrypt.so are missing, such as yum install libbeecrypt.la

2 > / usr/bin/ld: cannot find-lelf

Solution: ln-s / usr/lib/libelf.so.1 / usr/lib/libelf.so

3 > / usr/bin/ld:can't not find-lselinux

Fix: missing libselinux and libselinux-devel packages, such as yum install libselinux

Four: frequently asked questions about Rsync synchronization:

Error one:

@ ERROR: auth failed on module xxxxx

Rsync: connection unexpectedly closed (90 bytes read so far)

Rsync error: error in rsync protocol data stream (code 12) at io.c

Solution: this is because the password is set incorrectly and you cannot log in successfully. Check rsync.pwd to see if the customer service matches. This can also happen if the rsync service is not started on the server side.

Error 2:

Password file must not be other-accessible

Continuing without password file

Password:

Solution: this is because the permissions of rsyncd.pwd rsyncd.sec are incorrect and should be set to 600. For example, chmod 600rsyncd.pwd

Error 3:

@ ERROR: chroot failed

Rsync: connection unexpectedly closed (75 bytes read so far)

Rsync error: error in rsync protocol data stream (code 12) at io.c

Solution: this is because the path path you set in rsync.conf does not exist. You need to create a new directory to enable synchronization.

Error 4:

Rsync: failed to connect to 218.107.243.2: No route to host

Rsync error: error in socket IO (code 10) at clientserver.c [receiver=2.6.9]

Solution: the other party is not powered on, the firewall is blocked, and there is a firewall blocking on the network, all of which are possible. To turn off the firewall is to open port 873 of tcp udp.

Fifth: problems that often occur during software installation:

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, install flex.

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)

Fix: missing beecrypt package, such as:

Http://sourceforge.net/projects/beecrypt download beecrypt-4.1.2.tar.gz

Then run the following command:

# tar-zxvf beecrypt-4.1.2.tar.gz

#. / configure

# make

# make install
