目錄
- 一、先安裝依賴包
- 1、安裝postgreSQL13
- 2、安裝postgresql13-devel依賴包
- 二、安裝psycopg2
- 1、直接安裝rpm包
- 2、使用tar包安裝
- 三、驗證
postgresql選取13.4版本
python分為python2.7與python3.7
psycopg2分為rpm包與tar源碼包

安裝步驟
rpm -ivh postgresql13-libs-13.4-1PGDG.rhel7.x86_64.rpm
rpm -ivh postgresql13-13.4-1PGDG.rhel7.x86_64.rpm
rpm -ivh postgresql13-server-13.4-1PGDG.rhel7.x86_64.rpm
rpm -ivh postgresql13-contrib-13.4-1PGDG.rhel7.x86_64.rpm
libicu-devel
llvm-toolset-7-clang
llvm5.0-devel
yum -y install libicu-devel
llvm5.0-devel（沒有包）
llvm-toolset-7-clang（沒有包）
強制安裝postgresql13-devel
安裝後隻有python2.7能用
1）先安裝python3.7
安裝編譯相關工具包
yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel yum install libffi-devel -y
下載下傳python3.7
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
tar -xvJf Python-3.7.0.tar.xz
編譯安裝
mkdir /usr/local/python3 #建立編譯安裝目錄
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install
建立軟連接配接
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
2）下載下傳适配 python3.7 的tar包
tar -vzxf psycopg2-2.9.1.tar.gz
cd psycopg2-2.9.1/
安裝前，需要配置 pg_config：
vim setup.cfg
配置 pg_config
3）setup.py安裝
編譯：
python3 setup.py build
安裝：
python3 setup.py install
import psycopg2
