[root@china python_tools]#
#以root权限打开终端，进入安装包的存放路径，解压安装包：
[root@china python_tools]# tar -xzvf Python-3.6.4.tgz
#进入解压好的安装包路径：
[root@china python_tools]# cd Python-3.6.4
#编译安装包，指定安装路径，并执行安装命令：
#注意：prefix参数用于指定将Python安装在新目录，防止覆盖系统默认安装的python
[root@china Python-3.6.4]# ./configure --prefix=/usr/local/python36
[root@china Python-3.6.4]# make && make install
#修改系统默认的Python路径，因为在终端中输入Python命令时默认是指向Python2.6.6
[root@china Python-3.6.4]# mv /usr/bin/python /usr/bin/python-2.6.6
建立新的软连接，指向Python-3.6.0：
注：这里的python36是第4步指定的安装路径，python3.6是Python包里的可执行程序
[root@china Python-3.6.4]# ln -s /usr/local/python36/bin/python3.6 /usr/bin/python
[root@china Python-3.6.4]# python

>>>
7、因为yum是依赖python的，所以这里我们修改了默认的python,就要要修改yum，让其运行指向旧的版本：
vi /usr/bin/yum
将第一行中的“#!/usr/bin/python”
修改为“#!/usr/bin/python-2.6.6”，保存即可安装pip
解决pip is configured with locations that require TLS/SSL问题
yum install openssl openssl-devel
[root@china Python-3.6.4]# rpm -qa|grep openssl
openssl-devel-1.0.1e-57.el6.x86_64
openssl098e-0.9.8e-17.el6.centos.2.x86_64
openssl-1.0.1e-57.el6.x86_64
cd /root/python_tools/Python-3.6.4/Modules
vim Setup
#修改配置
# Socket module helper for socket(2)
_socket socketmodule.c
#SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \

修改完毕后保存。
# 重新编译

安装java
[root@china javatools]# chmod a+x jdk-6u45-linux-i586.bin
[root@china javatools]# ./jdk-6u45-linux-i586.bin
#修改jdk目录
[root@china javatools]# mv jdk1.6.0_45/ /usr/java/jdk1.6.0_45
[root@china javatools]# ls
jdk-6u45-linux-i586.bin
[root@china javatools]# cd /usr/java/
[root@china java]# ls
jdk1.6.0_45
[root@china java]# cd jdk1.6.0_45/
#设置环境变量
vi /etc/profile
在最后加上:
##use for JAVA 1.6
JAVA_HOME=/usr/java/jdk1.6.0_45
PATH=$JAVA_HOME/bin:$PATH
CLATHPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export JAVA_HOME PATH CLATHPATH
检查环境变量是否配成功：
echo $JAVA_HOME
echo $PARH
echo $CLATHPATH
检查jdk是否安装成功
[root@china jdk1.6.0_45]# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) Server VM (build 20.45-b01, mixed mode)
[root@china jdk1.6.0_45]# javac
用法：javac <选项> <源文件>
其中，可能的选项包括：
-g 生成所有调试信息
-g:none 不生成任何调试信息
-g:{lines,vars,source} 只生成某些调试信息
-nowarn 不生成任何警告
-verbose 输出有关编译器正在执行的操作的消息
升级openssl（拓展）
wget https://www.openssl.org/source/openssl-1.0.2h.tar.gz
tar xzvf openssl-1.0.2h.tar.gz
cd openssl-1.0.2h
./config --prefix=/usr shared zlib-dynamic
#提醒需要在build之前做make depend
make depend
rm -f /usr/bin/openssl
rm -f /usr/include/openssl
make && make install
ln -sf /usr/include/openssl/*.h /usr/include/
ln -sf /usr/lib/openssl/engines/*.so /usr/lib/
ldconfig -v
openssl version -a
[root@china bin]# openssl version -a
