postgresql在liunx系統安裝部署測試
阿新 • • 發佈：2018-11-11
一、下載postgresql
wget https://ftp.postgresql.org/pub/source/v10.3/postgresql-10.3.tar.gz
二、下載zlib，因為安裝報錯
http://www.zlib.net/
類似的錯誤：
configure: error: readline library notfound If you have readline already installed, see config.log for detailson the failure. It is possible the compiler isnt lookingin the proper directory. Use --without-readline to disable readlinesupport.
三、安裝zlib
tar zlib-1.2.11
cd zlib-1.2.11/
./configure
make && make install
四、安裝postgresql
./configure --prefix=/home/postgreSql10 --without-readline
make && make install
五、建立postgres使用者與組
groupadd postgres useradd -g postgres postgres chown postgres:postgres /home/pgdatabase -R
六、修改環境變數
export PGHOME=/home/postgresql/postgresql-10.3
export PGDATA=/home/postgresql/postgresql-10.3/pgdatabase
export PATH=$PATH:$HOME/bin:/home/postgreSql10/bin
export PG_PATH=/home/postgreSql10/bin
export PATH=$PG_PATH:$PATH
加入後通過按 esc 按：wq儲存並退出，通過source /etc/profile
七、初始化資料庫
initdb -D /home/postgresql/postgresql-10.3/pgdatabase -E UTF-8 --locale=zh_CN.UTF-8
八、修改配置進行遠端連線
8.1、修改postgresql.conf
將行開頭都#去掉，將行內容修改為listen_addresses=’*'來允許資料庫伺服器監聽來自任何主機的連線請求。
8.2、修改pg_hba.conf
表示允許網段0.0.0.0上的所有主機使用所有合法的資料庫使用者名稱訪問資料庫，
md5並提供加密的密碼驗證
host all all 0.0.0.0/0 md5
trust意思不用密碼驗證
host all all 0.0.0.0/0 trust
九、啟動 PostgreSQL
先切換使用者
啟動
pg_ctl -D /home/super/soft/pgdatabase/ start
關閉
pg_ctl -D /home/super/soft/pgdatabase/ stop
重啟
pg_ctl -D /home/super/soft/pgdatabase/ reload
10、 檢視當前資料庫的狀態
ps -ef|grep postgres
11、連線資料庫
psql -p 5432 -U postgres -d postgres
create database test;
12、修改密碼
ALTER USER postgres with encrypted password '123456';
13、springboot+postgresql的演示

}
大功告成
