1.访问http://www.cpan.org/authors/id/S/SH/SHAY/ 下载perl版本
2.将下载下来的安装包放到你的目录里边
# 解包 tar -zxvf perl-5.26.1.tar.gz # 进入文件目录 cd perl-5.26.1
进入解压目录执行
./Configure --help查看过后，使用这个指令来设置源码
./Configure -des -Dprefix=/usr/local/perl -Dusethreads -Uversiononly编译
# make //这个过程会比较久，因为源码文件有那么大，我的这个有14M。
# make install
等待这个命令完成后，基本安装就完成了
测试 执行 Perl -v

3.重定向
# 上一步完成基本代表着你已经把相关的perl安装成功
# 但是系统默认的还是原来的perl，所以我们要建立软连接
# 当前perl
perl -v

perl模块安装
以Net::SNMP模块为例
# 下载安装包
wget http://search.cpan.org/CPAN/authors/id/D/DT/DTOWN/Net-SNMP-v6.0.1.tar.gz
# 解压
tar -zxvf Net-SNMP-v6.0.1.tar.gz
# 编译安装
cd Net-SNMP-v6.0.1
perl Makefile.PL
make && make test
make install
# 特别注意
# 有一些模块使用Build.PL,可以通过readme进行查看
# 手动安装一定要先把依赖检测一下，先安装依赖

cpan安装
使用Perl自带的模块——CPAN.pm模块
perl -MCPAN -e shell
# 第一次进入选站点
Terminal does not support AddHistory.
cpan shell -- CPAN exploration and modules installation (v2.18)
Enter 'h' for help.
cpan[1]> install Net::SNMP

or
perl -MCPAN -e 'install Net::SNMP'- 1
常见错误
wget未安装
# 例：
wget command not found- 1
- 2
解决方法： yum -y install wget
gcc未安装
运行会提示带有cc的语句，因为我的环境一般都安装了gcc，也就不举例了
解决方法： yum -y install gcc
cpan未安装
Can't locate CPAN.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .).
BEGIN failed--compilation aborted.- 1
- 2
解决方法：
- yum -y install perl-CPAN
- 手动安装，版本要合适，步骤如上Net::SNMP
依赖未安装
# 例如
Checking prerequisites...
recommends:
* Crypt::DES is not installed
* Crypt::Rijndael is not installed
* Digest::HMAC is not installed
* Digest::SHA1 is not installed
* Socket6 is not installed- 1
