1.获取源码
从PostgreSQL: File Browser获取tar.bz2或者tar.gz源码
2.解压
tar xf postgresql-version.tar.bz2root@hwz-VMware-Virtual-Platform:/usr/local# tar xf postgresql-16.6.tar.bz2
root@hwz-VMware-Virtual-Platform:/usr/local# ll

root@hwz-VMware-Virtual-Platform:/usr/local/postgresql-16.6# ./configure --prefix=/usr/local/pgsql16可能会缺少库，按需安装即可
make&make install编译后生成目录

先增加一个postgresql用户
useradd postgres
passwd postgres创建数据目录并让它属于postgres用户
root@hwz-VMware-Virtual-Platform:/usr/local/pgsql16# useradd -m postgres
root@hwz-VMware-Virtual-Platform:/usr/local/pgsql16# chown postgres . /pgdata/16/data官方useradd postgres 不加-m参数 Ubuntu可能不会创建用户家目录
root@hwz-VMware-Virtual-Platform:/usr/local/pgsql16# su - postgres
postgres@hwz-VMware-Virtual-Platform:~$ ll
这种前面只有$是因为该用户shell为/bin/sh，需要改为/bin/bash
4.1 设置环境变量
postgres@hwz-VMware-Virtual-Platform:~$ vim .bash_profileexport PGDATA=/pgdata/16/data
export LANG=en_US.utf8
export PGHOME=/usr/local/pgsql16
export
LD_LIBRARY_PATH=$PGHOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH
export DATE=`date +"%Y%m%d%H%M"`
export PATH=$PGHOME/bin:$PATH:.
export MANPATH=$PGHOME/share/man:$MANPATH
export PGUSER=postgres测试是否成功
postgres@hwz-VMware-Virtual-Platform:~$ psql --version
psql (PostgreSQL) 16.4.2 初始化
postgres@hwz-VMware-Virtual-Platform:~$ initdb -D /pgdata/16/data/
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
initdb: error: invalid locale settings; check LANG and LC_* environment variables
如果出现这个错误是因为 当前用户环境使用的编码和系统编码不一致

postgres@hwz-VMware-Virtual-Platform:~$ vim /etc/locale.conf

现在修改用户环境的编码为CN UTF-8
postgres@hwz-VMware-Virtual-Platform:~$ vim .bashrc后面添加
export LC_ALL="zh_CN.UTF-8"
postgres@hwz-VMware-Virtual-Platform:~$ source .bashrc

postgres@hwz-VMware-Virtual-Platform:~$ initdb -D /pgdata/16/data/
The files belonging to this database system will be owned by user "postgres".
