3. 软件安装

3.2 RPM方式安装（PG 14）

3.2.1 下载RPM安装包

https://yum.postgresql.org/rpmchart/

postgresql14 - PostgreSQL client programs and libraries
postgresql14-contrib - Contributed source and binaries distributed with PostgreSQL
postgresql14-libs - The shared libraries required for any PostgreSQL clients
postgresql14-server - The programs needed to create and run a PostgreSQL server

3.2.2 安装RPM包 PG14

[root@pgdb soft]# rpm -ivh postgresql14-*

3.2.3 初始化数据库

[root@pgdb ~]# su - postgres
[postgres@pgdb ~]$ /usr/pgsql-14/bin/initdb -D /pgdata/data/pg14
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 "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".Data page checksums are disabled.fixing permissions on existing directory /pgdata/data/pg14 ... 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 ... okinitdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.Success. You can now start the database server using:/usr/pgsql-14/bin/pg_ctl -D /pgdata/data/pg14 -l logfile start

3.2.4 启动数据库

[postgres@pgdb ~]$ /usr/pgsql-14/bin/pg_ctl -D /pgdata/data/pg14 -l logfile start
waiting for server to start.... done
server started
[postgres@pgdb ~]$ /usr/pgsql-14/bin/pg_ctl status
pg_ctl: server is running (PID: 36530)
/usr/pgsql-14/bin/postgres "-D" "/pgdata/data/pg14"

3.2.5 开机自启动

• 修改自启动配置文件路径

# 修改配置文件路径
vi /usr/lib/systemd/system/postgresql-14.service
# Location of database directory
#Environment=PGDATA=/var/lib/pgsql/14/data/
Environment=PGDATA=/pgdata/data/pg14ExecStartPre=/usr/pgsql-14/bin/postgresql-14-check-db-dir ${PGDATA}
ExecStart=/usr/pgsql-14/bin/postmaster -D ${PGDATA}

• enable开机启动服务

# reload配置文件
[root@pgdb ~]# systemctl daemon-reload
# 启动数据库
[root@pgdb ~]# systemctl start postgresql-14.service
# 开机自启动
[root@pgdb ~]# systemctl enable postgresql-14.service
Created symlink /etc/systemd/system/multi-user.target.wants/postgresql-14.service → /usr/lib/systemd/system/postgresql-14.service.
# pg14 资源状态
[root@pgdb ~]# systemctl status postgresql-14.service

3.2.6 编辑环境变量

• 编辑环境变量

vi .bash_profile
#PG 14
######
export PGPORT=5432
export PGDATA=/pgdata/data/pg14
export PGHOME=/usr/pgsql-14

• 验证环境变量

[postgres@pgdb ~]$ source .bash_profile
[postgres@pgdb ~]$ which pg_ctl
/usr/pgsql-14/bin/pg_ctl
