Install PostgreSql 10 to Fedora 27
國慶以後，雲棲大會杭州分會上相關專家作了一個關於Postgresql的專題分享，其中提到了Postgresql 10的一些新特性，我的感受倍受鼓舞，接下來但願分別針對Ubuntu 16.04LTS和Fedora27上如何安裝並配置Postgresql 10作一個簡要介紹。這篇博客主要針對Fedora 27作簡要介紹。linux
一、安裝
你們進入Postgresql官網下載頁面，選擇
數據版本postgreql10，Linux 發行套件Fedora 27，而後選擇64位，即x86_64，這個時候就會出現相關的安裝腳本。sql
1.1 、添加軟件源
lwk@fedora1 ~ $ sudo dnf install https://download.postgresql.org/pub/repos/yum/10/fedora/fedora-27-x86_64/pgdg-fedora10-10-3.noarch.rpm Last metadata expiration check: 7:30:40 ago on Tue 02 Jan 2018 10:32:40 AM CST. pgdg-fedora10-10-3.noarch.rpm 6.9 kB/s | 8.8 kB 00:01 Dependencies resolved. ============================================================================================================================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================================================================================================================== Installing: pgdg-fedora10 noarch 10-3 @commandline 8.8 k Transaction Summary ============================================================================================================================================================================================================================================== Install 1 Package Total size: 8.8 k Installed size: 3.2 k Is this ok [y/N]: y Downloading Packages: Running transaction check Transaction check succeeded.

1.二、安裝服務器與客戶端

這裏要說的是dnf和yum是相似的，在性能上比yum更高效，這也是接下來

1.三、初始化
lwk@fedora1 ~ $ sudo /usr/pgsql-10/bin/postgresql-10-setup initdb
Initializing database ... OK
lwk@fedora1 ~ $ sudo systemctl enable postgresql-10.service
Created symlink /etc/systemd/system/multi-user.target.wants/postgresql-10.service → /usr/lib/systemd/system/postgresql-10.service.
lwk@fedora1 ~ $ sudo systemctl start postgresql-10.service
lwk@fedora1 ~ $ sudo systemctl status postgresql-10.service

1.四、本地訪問
postgres@fedora1 ~ $ psql
psql (10.1)
Type "help" for help.
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
(3 rows)
postgres=#
二、配置
咱們知道一般狀況下，須要在主機之外的主機上訪問postgresql服務，可是默認狀況下，postgresql僅僅只提供本地訪問，要讓其餘主機也能夠訪問，須要作以下配置。vim
2.一、開放對非地訪問的支持。
fedora旗下發行套件中的postgresql配置文件主要在數據目錄，即/var/lib/pgsql/10/data/下服務器
postgres@fedora1 ~ $ psql
psql (10.1)
Type "help" for help.

-rw-------. 1 postgres postgres 103 Jan 2 18:07 postmaster.pid
postgres@fedora1 ~ $
咱們先修改配置postgresql.conf，打開對非主機訪問的限制，用vim打開該文件，app
59 #listen_addresses = 'localhost' # what IP address(es) to listen on;
修改成
59 #listen_addresses = '*' # what IP address(es) to listen on;ssh
再用vim打開文件pg_hba.conf，找到82行socket
82 host all all 127.0.0.1/32 ident
後面追加ide
83 host all all 192.168.1.0/24 trust
這時，從新啓動postgresql數據庫。工具
postgres@fedora1 ~ $ vim /var/lib/pgsql/10/data/postgresql.conf
postgres@fedora1 ~ $ vim /var/lib/pgsql/10/data/pg_hba.conf
postgres@fedora1 ~ $ exit
logout
lwk@fedora1 ~ $ sudo systemctl start postgresql-10.service
[sudo] password for lwk:
lwk@fedora1 ~ $ sudo systemctl status postgresql-10.service

2.一、修改防火牆配置。
修改防火牆配置將將端口號5432添加到防火牆白名單中去。方法不少，這裏採用ufw
