【PostgreSQL】从零开始:（二）PostgreSQL下载与安装
Winodws环境下载与安装PostgreSQL
下载PostgreSQL
也可以直接丁路到EDB网站直接下载 【下载地址】
安装PostgreSQL
安装完成后，如果勾选：Stack Builder may be used to download and install additional tools,drivers and applications to complement your PostgreSQL installation. 在Finish之后会运行Stack Builder，可用于下载和安装附加的工具、驱动程序和应用程序，以补充PostgreSQL安装。可以不勾选，勾选了会运行 Stack Builder安装插件。（本次安装不附带Stack Builder安装，附录可以了解Stack Builder安装插件相关内容）
1.登录数据库
2.查看下我们已有的数据库
Liunx环境下载与安装PostgreSQL
使用YUM下载安装PostgreSQL
下面我们来演示一下
1.下载PostgreSQL安装包
https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
执行结果:
[root@postgre-sql ~]# yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

2.安装PostgreSQL
折腾了半天，发现centos7的yum只有PostgreSQL15版本：见附录，那我们就以15作为演示
yum install-y postgresql15-server

2.创建用户组及用户并修改密码
[root@postgre-sql ~]# groupadd postgres[root@postgre-sql ~]# useradd -g postgres postgres[root@postgre-sql ~]# passwd postgres
新的 密码：
无效的密码： 密码未通过字典检查 - 过于简单化/系统化
重新输入新的 密码：
passwd：所有的身份验证令牌已经成功更新。
[root@postgre-sql ~]#
3.修改root用户配置参数，并让其生效
[root@postgre-sql ~]# vi .bash_profile [root@postgre-sql ~]# cat .bash_profile # .bash_profile# Get the aliases and functionsif[-f ~/.bashrc ];then. ~/.bashrc
fi# User specific environment and startup programsPATH=$PATH:$HOME/bin

[root@postgre-sql postgresql_install]#
7.进入数据库源文件目录，给configure加运行权限
[root@postgre-sql postgre_install]# cd postgresql-16.1/[root@postgre-sql postgresql-16.1]# chmod +x configure
8.执行以下语句开始编译PostgreSQL
./configure --prefix=${POSTGRESQL_PATH} --with-pgport=${POSTGRESQL_PORT}makemakeinstall
然后再执行
9.查看数据库文件
[root@postgre-sql postgresql-16.1]# cd /opt/postgresql-16.1/[root@postgre-sql postgresql-16.1]# ls -l

这里我们已经编译成功了
10.配置postgres用户环境变量
[postgres@postgre-sql ~]$ vi .bash_profile
[postgres@postgre-sql ~]$ cat .bash_profile
# .bash_profile# Get the aliases and functionsif[-f ~/.bashrc ];then. ~/.bashrc
fi# User specific environment and startup programsPATH=$PATH:$HOME/.local/bin:$HOME/bin
## 新添加配置exportPOSTGRESQL_USER=postgres
exportPOSTGRESQL_GROUP=postgres
exportPOSTGRESQL_INSTALL_PATH=/root/postgresql_install
exportPOSTGRESQL_VERSION=16.1exportPOSTGRESQL_PATH=/opt/postgresql-${POSTGRESQL_VERSION}exportPOSTGRESQL_PORT=5432exportPOSTGRESQL_DATA=/data/${POSTGRESQL_VERSION}/data
exportLD_LIBRARY_PATH=${POSTGRESQL_PATH}/lib:/usr/local/lib:$LD_LIBRARY_PATHexportPATH=${POSTGRESQL_PATH}/bin:$PATHexportPGDATA=${POSTGRESQL_DATA}exportPATH[postgres@postgre-sql ~]$ source .bash_profile
[postgres@postgre-sql ~]$ echo$PGDATA
/data/16.1/data
[postgres@postgre-sql ~]$
11.创建数据库实例
[postgres@postgre-sql ~]$ initdb -A md5 -D$PGDATA-E'UTF8'--pwfile=<(printf"%s""12345678ab")
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "zh_CN.UTF-8".
initdb: could not find suitable text search configuration for locale "zh_CN.UTF-8"
The default text search configuration will be set to "simple".
Data page checksums are disabled.
creating directory /data/16.1/data ... ok
creating subdirectories ... ok
selecting dynamic shared memory implementation ... posix
selecting default max_connections ... 100
selecting default shared_buffers ... 128MB
selecting default time zone ... Asia/Shanghai
creating configuration files ... ok
running bootstrap script ... ok
performing post-bootstrap initialization ... ok
syncing data to disk ... ok
Success. You can now start the database server using:
pg_ctl -D /data/16.1/data -l logfile start
[postgres@postgre-sql ~]$
12.启动数据库
[postgres@postgre-sql ~]$ pg_ctl -D /data/16.1/data start

[postgres@postgre-sql ~]$
13.登陆数据库
[postgres@postgre-sql ~]$ psql -U postgres -d postgres
Password for user postgres:
psql (16.1)
Type "help"for help.

登陆数据库并查看到了数据库列表，到这里部署已经完成了
