PG源碼編譯安裝

 

系統資源限制設置

vi /etc/security/limits.conf

* soft nofile  1024000
* hard nofile  1024000
* soft noproc  1024000
* hard noproc  1024000
* soft core    1024000
* hard core    1024000
* soft memlock 1024000
* hard memlock 1024000

 

vi /etc/security/limits.d/20-nproc.conf

*          soft    nproc     unlimited
root       soft    nproc     unlimited

SELINUX和防火牆設置

vi /etc/sysconfig/selinux

SELINUX=disabled
SELINUXTYPE=targeted

OS防火牆（建議按業務場景設置，不需要就先刪除所有策略，並關閉服務）

方法1

#設置默認接受所有請求
/sbin/iptables -P INPUT ACCEPT
#清除防火牆規則
/sbin/iptables -F

方法2

關閉防火牆
systemctl disable firewalld.service
systemctl stop firewalld.service

創建組及用戶，並設置密碼

groupadd postgres
useradd -g postgres -m postgres
passwd postgres

源碼包下載

https://www.postgresql.org/ftp/source/v12.2/
postgresql-12.2.tar.gz

檢查依賴包

rpm -q openssl  \
openssl-devel  \
pam  \
pam-devel  \
libxml2  \
libxml2-devel  \
libxslt  \
libxslt-devel  \
perl  \

python-devel  \

zlib  \
zlib-devel  \
gettext  \

bison  \
flex  \
uuid-devel  \
gcc  \
gcc-c++ \
systemd

配置yum源參考

安裝依賴包

yum install -y openssl \
openssl-devel  \
pam  \

上傳源碼包到/pg-rpm

[root@centos7-6 ~]# mkdir /pg-rpm

解壓並設置權限

cd /pg-rpm/
tar -zxvf postgresql-12.2.tar.gz
chown -R postgres:postgres postgresql-12.2

創建pg安裝目錄

mkdir -p /opt/pg12
chown postgres:postgres /opt/pg12

切換用戶

su - postgres

編譯安裝

cd /pg-rpm/postgresql-12.2

./configure \
--prefix=/opt/pg12 \
--with-pgport=9527 \
--with-openssl  \
--with-perl \
--with-python \
--with-blocksize=16 \
--with-systemd

如果加上“--with-systemd”后報錯如下：

configure: error: header file <systemd/sd-daemon.h> is required for systemd support

則需要檢查是否安裝了systemd相關包，在這次驗證中缺少的是 systemd-devel-219-62.el7.x86_64 

參數詳解

---------------
./configure --prefix=PREFIX
把所有文件裝在目錄PREFIX中而不是/usr/local/pgsql中。 
實際的文件會安裝到數個子目錄中；沒有一個文件會直接安裝到PREFIX根目錄里。
結果如下：
[postgres@centos7-6 ~]$ ls  /opt/pg12/
bin  include  lib  share
[postgres@centos7-6 ~]$


--with-pgport=NUMBER
把NUMBER設置為服務器和客戶端的默認端口。默認是 5432。 這個端口可以在以后修改，不過如果你在這里聲明，那么服務器和客戶端將有相同的編譯好了的默認值。這樣會非常方便些。 通常選取一個非默認值的理由是你企圖在同一台機器上運行多個PostgreSQL服務器。

--with-openssl
編譯SSL（加密）連接支持。這個選項需要安裝OpenSSL包。configure將會檢查所需的頭文件和庫以確保你的 OpenSSL安裝足以讓配置繼續下去。

--with-perl
制作PL/Perl服務器端編程語言。

--with-python
制作PL/Python服務器端編程語言。

--with-blocksize=BLOCKSIZE
設置塊尺寸，以 K 字節計。這是表內存儲和I/O的單位。默認值（8K字節）適合於大多數情況，但是在特殊情況下可能其他值更有用。這個值必須是2的冪並且在 1 和 32 （K字節）之間。注意修改這個值需要一次 initdb。

--with-systemd
系統服務方式管理

---------------

編譯

make world

執行完成后顯示的最后一行應該是：
PostgreSQL, contrib, and documentation successfully made. Ready to install.

注：
源碼安裝postgresql時，而make時又沒有make world，就會導致的pg最終沒有類似pg_stat_statements的擴展功能
如果選擇make ,后續手動安裝pg擴展插件，請參考https://www.cnblogs.com/ejQiu-123/p/11497362.html
make
（一定要記得用GNU make）。依你的硬件而異，編譯過程可能需要 5 分鍾到半小時。顯示的最后一行應該是：

如果你希望編譯所有能編譯的東西，包括文檔（HTML和手冊頁）以及附加模塊（contrib），這樣鍵入：
make world

安裝PostgreSQL

make install-world

執行完成后顯示的最后一行應該是：
PostgreSQL, contrib, and documentation installation complete.

查看安裝后的目錄結構

[postgres@centos7-6 ~]$ ls  /opt/pg12/
bin  include  lib  share
[postgres@centos7-6 ~]$

創建數據存放目錄並設置權限

[postgres@centos7-6 ~]$ mkdir /opt/pg12/data

[postgres@centos7-6 ~]$ chown postgres:postgres /opt/pg12/data

配置環境變量

[postgres@centos7-6 ~]$ vi ~/.bash_profile

export PGHOME=/opt/pg12
export PGPORT=9527
export PGDATA=/opt/pg12/data
export LD_LIBRARY_PATH=$PGHOME/lib:LD_LIBRARY_PATH
export PATH=$PGHOME/bin:$PATH
export PATH=/usr/local/pgsql/bin:$PATH:.

生效環境變量

source ~/.bash_profile

創建一個數據庫集簇

[postgres@centos7-6 ~]$ initdb -D /opt/pg12/data -E UTF8 --locale=zh_CN.utf8
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.utf8".
initdb: could not find suitable text search configuration for locale "zh_CN.utf8"
The default text search configuration will be set to "simple".

Data page checksums are disabled.

initdb: 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:

    pg_ctl -D /opt/pg12/data -l logfile start

使用systemctl來管理postgres的服務了

vi /etc/systemd/system/postgresql.service

[Unit]
Description=PostgreSQL database server
Documentation=man:postgres(1)

[Service]
Type=notify
User=postgres
ExecStart=/opt/pg12/bin/postgres -D /opt/pg12/data
ExecReload=/bin/kill -HUP $MAINPID
KillMode=mixed
KillSignal=SIGINT
TimeoutSec=0

[Install]
WantedBy=multi-user.target

使用systemctl來管理postgres的服務

注:使用systemctl，就需要編譯安裝時加上參數：--with-systemd

systemctl start postgresql.service
systemctl status postgresql.service
systemctl stop postgresql.service
systemctl disable postgresql.service
systemctl enable postgresql.service
