初始化mysql数据库时出现下面错误，原因是缺少Data:dumper模块
解决方法 ：安装autoconf库
命令：yum -y install autoconf //此包安装时会安装Data:Dumper模块
[root@bogon mysql]# yum -y install autoconf 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * base: mirror.bit.edu.cn * extras: mirror.bit.edu.cn * updates: mirror.bit.edu.cn 正在解决依赖关系 --> 正在检查事务 ---> 软件包 autoconf.noarch.0.2.69-11.el7 将被 安装 --> 正在处理依赖关系 m4 >= 1.4.14，它被软件包 autoconf-2.69-11.el7.noarch 需要 --> 正在处理依赖关系 perl(Data::Dumper)，它被软件包 autoconf-2.69-11.el7.noarch 需要 --> 正在检查事务 ---> 软件包 m4.x86_64.0.1.4.16-10.el7 将被 安装 ---> 软件包 perl-Data-Dumper.x86_64.0.2.145-3.el7 将被 安装 --> 解决依赖关系完成 依赖关系解决 ================================================================================================================================ Package 架构 版本 源 大小 ================================================================================================================================ 正在安装: autoconf noarch 2.69-11.el7 base 701 k 为依赖而安装: m4 x86_64 1.4.16-10.el7 base 256 k perl-Data-Dumper x86_64 2.145-3.el7 base 47 k 事务概要 ================================================================================================================================ 安装 1 软件包 (+2 依赖软件包) 总下载量：1.0 M 安装大小：2.8 M Downloading packages: (1/3): perl-Data-Dumper-2.145-3.el7.x86_64.rpm | 47 kB 00:00:00 (2/3): autoconf-2.69-11.el7.noarch.rpm | 701 kB 00:00:00 (3/3): m4-1.4.16-10.el7.x86_64.rpm | 256 kB 00:00:02 -------------------------------------------------------------------------------------------------------------------------------- 总计 455 kB/s | 1.0 MB 00:00:02 Running transaction check Running transaction test Transaction test succeeded Running transaction 正在安装 : m4-1.4.16-10.el7.x86_64 1/3 正在安装 : perl-Data-Dumper-2.145-3.el7.x86_64 2/3 正在安装 : autoconf-2.69-11.el7.noarch 3/3 验证中 : perl-Data-Dumper-2.145-3.el7.x86_64 1/3 验证中 : m4-1.4.16-10.el7.x86_64 2/3 验证中 : autoconf-2.69-11.el7.noarch 3/3 已安装: autoconf.noarch 0:2.69-11.el7 作为依赖被安装: m4.x86_64 0:1.4.16-10.el7 perl-Data-Dumper.x86_64 0:2.145-3.el7 完毕！安装完autoconf库，再运行./scripts/mysql_install_db --user=mysql，问题消失！！！
------------------------------------------------------------
下面再备上源码安装autoconf
下载地址：http://ftp.gnu.org/gnu/autoconf/
我这里选择的是2.69版本下载http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
[root@bogon liuzhen]# tar -zxvf autoconf-2.69.tar.gz [root@bogon liuzhen]# cd autoconf-2.69 [root@bogon autoconf-2.69]# ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu configure: autobuild project...

GNU M4 1.4.6 or later is required; 1.4.16 or newer is recommended. GNU M4 1.4.15 uses a buggy replacement strstr on some systems. Glibc 2.9 - 2.12 and GNU M4 1.4.11 - 1.4.15 have another strstr bug.执行./configure时出现下面错误：
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.
原因是需要安装M4
打开m4下载地址：
http://ftp.gnu.org/gnu/m4/
我这里下载的是最新版本http://ftp.gnu.org/gnu/m4/m4-1.4.18.tar.gz
[root@bogon liuzhen]# tar -zxvf m4-1.4.18.tar.gz [root@bogon liuzhen]# cd m4-1.4.18 [root@bogon m4-1.4.18]# ./configure [root@bogon m4-1.4.18]# make [root@bogon m4-1.4.18]# make installm4安装完成之后再次执行再次切换到autoconf目录继续安装
[root@bogon liuzhen]# cd autoconf-2.69 [root@bogon autoconf-2.69]# ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu configure: autobuild project...

configure: error: perl is not found
是因为没有安装perl
可以快速yum安装，也可以向下看源码安装
[root@bogon liuzhen]# yum -y install perl perl-devel下载地址：https://www.perl.org/get.html
源码包地址：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 installperl安装完成之后再次执行再次切换到autoconf目录继续安装
[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至此autoconf通过源码方式安装完成
