注：
本次升级是在初始安装了openGauss 2.0.0集群的基础上，通过先升级到2.0.1，再升级到2.1.0一路打怪升级基础上，想尝试升级到3.1.0。因为未在网上找到openGauss 2升级到 openGauss 3的文档，所以尝试尝鲜使用2.1.0升级到3.1.0。
2.1.0的升级都还比较顺利，但在升级到3.1.0的时候遇到一些坑，比如首先预检查时遇到python3编译不通过的问题，最后尝试加参数重新编译通过预检查。再升级后，查看升级过程信息，发现有failed信息，但检查集群数据库版本也都升级到了3.1.0.
升级后，在执行主备切换的时候，也遇到主备不能正常切换的问题，但将集群停了，仍能正常启动集群，对于这方面的问题，还在摸索学习中。
在实际升级测试过程中，也确实感受到了3.1.0和之前版本升级的一些变化。
第一次做这样的升级，升级过程难免有遗漏和问题，还望这方面的大牛能多多指正。
一、准备工作
1.1 下载3.1.0 软件包
-- 移动 /opt/software/openGauss 目录下除 clusterconfig.xml文件外 至 备份目录
-- 下载 2.1.0 软件包至节点一 /opt/software/openGauss目录

三、补充
3.1 python编译报错

Exception: [GAUSS-52200] : When compiling python, carry the -enable-shared and -fpic parameters
--最初执行的python编译命令是如下
./configure --prefix=/usr/local/python3 --enable-shared -- 在2.1.0升级前没问题，但升级到3.1.0时会报错
echo "/usr/local/python3/lib/" >> /etc/ld.so.conf
ldconfig
echo "/usr/local/python3/lib/" >> /etc/ld.so.conf
ldconfig
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
此时应该对python3重新采用如下方法编译 ./configure --prefix=/usr/local/python3 --enable-shared CFLAGS=-fPIC
