The following error occurred while initializing the mysql database due to the missing Data:dumper module

After installing the autoconf library, run. / scripts/mysql_install_db-- user=mysql, the problem disappears!
Next, install autoconf with source code.

What I choose here is version 2.69 to download http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz.

The following error occurred while executing. / configure:
Checking for GNU M4 that supports accurate traces... Configure: error: no acceptable M4 could be found in $PATH.
GNU M4 1.4.6 or later is required; 1.4.16 or newer is recommended.
The reason is that M4 needs to be installed
Open the M4 download address:
Http://ftp.gnu.org/gnu/m4/
What I download here is the latest version of http://ftp.gnu.org/gnu/m4/m4-1.4.18.tar.gz.

M4 after the installation is complete, execute again and change to the autoconf directory to continue the installation.

Because perl is not installed
You can install yum quickly, or look down at the source code installation.
[root@bogon liuzhen] # yum-y install perl perl-devel
Download address: https://www.perl.org/get.html
Source code packet address: http://www.cpan.org/src/5.0/perl-5.24.0.tar.gz
[root@bogon liuzhen] # tar-zxvf perl-5.24.0.tar.gz [root@bogon liuzhen] # cd perl-5.24.0 [root@bogon perl-5.24.0] #. / Configure [root@bogon perl-5.24.0] # make [root@bogon perl-5.24.0] # make install
After the perl installation is complete, execute again and change to the autoconf directory again to continue the installation.
[root@bogon liuzhen] # cd autoconf-2.69 [root@bogon autoconf-2.69] #. / configure [root@bogon autoconf-2.69] # make [root@bogon autoconf-2.69] # make install
So far, autoconf has been installed through source code.
