centos要用python3.6

euler用3.7 tar -zxvf Python-3.6.11.tgz cd Python-3.6.11 ./configure --prefix=/usr/python3.6.11 --enable-optimizations --enable-shared CFLAGS=-fPIC make make install ## 环境变量配置(不要覆盖python2,否则yum命令使用可能存在问题) ln -s /usr/python3.6.11/bin/python3.6 /usr/bin/python3 ln -s /usr/python3.6.11/bin/pip3 /usr/bin/pip3 ln -s /usr/python3.6.11/lib/libpython3.6m.so.1.0 /usr/lib64/ export LD_LIBRARY_PATH=/usr/python3.6.11/lib:$LD_LIBRARY_PATH 手动安装需要包安装python3的rpm包(因为有依赖关系，请按顺序执行) 3. 查看软件包安装情况 rpm -ivh python-srpm-macros-3-32.el7.noarch.rpm rpm -ivh python-rpm-macros-3-32.el7.noarch.rpm rpm -ivh python3-rpm-macros-3-32.el7.noarch.rpm ## 以下4个包(python3-pip/python3/python3-libs/python3-setuptools)存在互相依赖性，必须同时安装 rpm -ivh python3-pip-9.0.3-7.el7_7.noarch.rpm python3-3.6.8- 13.el7.x86_64.rpm python3-libs-3.6.8-13.el7.x86_64.rpm python3- setuptools-39.2.0-10.el7.noarch.rpm rpm -ivh python3-rpm-generators-6-2.el7.noarch.rpm rpm -ivh python3-devel-3.6.8-13.el7.x86_64.rpm [root@db3 ~]# rpm -qa|grep python3 python3-rpm-macros-3-32.el7.noarch python3-setuptools-39.2.0-10.el7.noarch python3-pip-9.0.3-7.el7_7.noarch python3-devel-3.6.8-13.el7.x86_64 python3-libs-3.6.8-13.el7.x86_64 python3-3.6.8-13.el7.x86_64 python3-rpm-generators-6-2.el7.noarch

环境准备

节点文件 接下来的操作在 主服务器 上进行即可
