Build my CentOS7
Learn some features of centos7, and do some daily exercises on it, write code or something. In order to facilitate the construction in the future, make a record.
Download and install
Download from the centos official website, the minimal iso image, only 500M.
Since I installed it on vmware workstation, it was not carved into a CD.
Created a virtual machine, 1G memory, 1 CPU, 20G hard disk, two network cards (one bridges the external network, one is only the host)
A user shalk was created during installation
In this way, I can use the ssh tool, the static IP of the internal network, and another network card to let the virtual machine access the external network.
Initial configuration
Use root user first
Minimize the installation process, use the default partition, and centos7 will use xfs as the file system. After installation, I found that there is no vim, no ifconfig, but it doesn't matter. With vi, you can use it to ip addr check the network situation
Configure an IP, modify /etc/sysconfig/network-script/ifcfg-device name
Modify the hostname, modify /etc/hostname
Add DNS, modify /etc/resolv.conf and add a line of nameserver 114.114.114.114
Restart the network /etc/init.d/network start
can go online
Modify /etc/sudoers and add a line to give the Shalk user permissions
shalk ALL=(ALL) ALL
Configure EPEL source
EPEL means Extra Package for Enterprise Linux, which is a set of high-quality additional software packages, mainly for Redhat, CenOS, Scientific Linux, etc. It is said that there are more than 10,000 rpm packages, add this source.
curl -O http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-1.noarch.rpm
sudo rpm -ivh epel-release-7-1.noarch.rpm
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
configure yum
Download a yum plugin to make yum faster
sudo yum install yum-axelget
Update all packages of the system
sudo yum update
Well, now use yum to install various packages.
Install the compiler
sudo yum install gcc
sudo yum install gcc-c++
sudo yum install make
Install the editor
sudo yum install vim
curl www.xxxx.com/vim -o ~/.vimrc 我的配置
install git
sudo yum install git
perl
perl -v
发现最小化没有perl,虽然我们不用系统的perl，但是如果系统如果缺perl，也会很麻烦。
sudo yum install perl-core
Version management with plenv
sudo yum install patch
If you don't install this, you will get an error when installing perl. Interestingly, this patch is also written by Larry Wall
git clone git://github.com/tokuhirom/plenv.git ~/.plenv
echo 'export PATH="$HOME/.plenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(plenv init -)"' >> ~/.bash_profile
exec $SHELL -l
Install two plugins
git clone git://github.com/tokuhirom/Perl-Build.git ~/.plenv/plugins/perl-build/
git clone git://github.com/shalk/plenv-update.git ~/.plenv/plugins/perl-update/
Install several versions of perl
plenv install 5.10.0 -Dusethreads
plenv rehash
plenv install 5.20.0 -Dusethreads
plenv rehash
python
python -V
Python 2.7.5
sudo yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel
sudo yum install openssl-devel
Install pyenv for version management
curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash
echo 'export PATH="$HOME/.pyenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
exec $SHELL - l
pyenv install 2.7.8 # 安装python2.7
pyenv install 3.4.0 # 安装python 3.4
