Installing Python3 virtual environments and Eclipse in Linux systems

Environment: VMware under CENTOS7

Using packages: eclipse-jee-neon-1a-linux-gtk-x86_64.tar.gz and PYTHON-3.6.1.TAR.XZ

If you need a friend you can download the package from the network tray

Installing Python 3.6 and the virtual development environment

1. Turn off the firewall and SELinux

Systemctl Stop Firewalld

Setenforce 0

Ps:selinux is a kind of file Protection in Linux, it is more convenient for us to operate

2. Configuring the Epel Yum Source

Vim/etc/yum.repos.d/epel.repo

[Epel]

Name=epel

baseurl=https://mirrors.aliyun.com/epel/7/x86_64/

Gpgcheck=0

What's in Epel.repo.

Cache Packages: Yum repolist

3. Installing dependent Packages

Yum-y install wget sqlite-devel xz gcc automake zlib-devel openssl-devel epel-release git

4. Import the Python installation package from Windows to the Linux system

Decompression: Tar xvf python-3.6.1.tar.xz

5. (source code) compile and install

CD Python-3.6.1

./configure && make && make install

6. Establishing an isolated environment py3

cd/opt/

Python3-m venv Py3

7. Writing using the PY3 environment

Source/opt/py3/bin/activate

Note: Centos7 installs Python2.7 by default. Yum relies on Python2.7, so it can only install the virtual development environment, not the unloaded load

Installation ECLIPSE*0.CENTOS7 must be a graphical-based installation method

1. Turn off the firewall and SELinux

Systemctl Stop Firewalld

Setenforce 0

2. Check the default JDK

Java-version

, there is usually a default JDK

3. Install Java:

Yum Install Java

4. Upload the Eclipse installation package from Windows to Linux and unzip to/opt/

Tar xzvf eclipse-jee-neon-1a-linux-gtk-x86_64.tar.gz-c/opt/

5. Match the "shortcut" with the program:

Soft connection

When Bin/eclipse is executed, it is actually performed/eclipse/eclipse

Just like Windows clicks a shortcut

Ln-s/opt/eclipse/eclipse/usr/bin/eclipse

6. Create a "shortcut"

Vim/usr/share/applications/eclipse.desktop

[Desktop Entry]

Encoding=utf-8

name=eclipse4.4.2

Comment=eclipse Lnua

Exec=/usr/bin/eclipse

icon=/opt/eclipse/icon.xpm

Categories=application;development; Java;ide

version=1.0

Type=application

Terminal=0

What's in Eclipse.desktop

7. Open Eclipse for code writing
