1. Preparations
The Postgresql environment demonstrated in this article is Postgresql 9.6
Installation method reference URL: https://my.oschina.net/corleone/blog/1575150
After installing postgresql9.6, remember to configure environment variables:
$: vi /etc/profile
// 由于postgresql9.6是默认安装，故在文件末尾添加如下内容
PATH=$PATH:/usr/pgsql-9.6/bin
$: source /etc/profile
Download the package:
﹒pgAgent-3.4.0-Source.tar.gz
pg_agent download address: https://www.pgadmin.org/download/pgagent-source-code/
Macmake-3.9.6.tar.gz
cmake download address: https://cmake.org/download/
﹒wxGTK-2.8.12.tar.gz
wxWidgets download address: http://www.wxwidgets.org/downloads/
Unzip the installation package:
$: cd /usr/local
$: mkdir pgagent
$: tar zxvf pgAgent-3.4.0-Source.tar.gz
$: tar zxvf cmake-3.9.6.tar.gz
$: tar xvf wxGTK-2.8.12.tar.gz
2. Install cmake
$: cd /usr/local/cmake-3.9.6
$: ./configure --prefix=/usr/local/cmake-3.9.6
$: make
$: make install
$: vi /etc/profile

export PATH=/usr/local/cmake-3.9.6/bin:$PATH
$: source /etc/profile
3. Install wxWidgets
Install gtk2-devel and binutils first
$: yum -y install gtk2-devel binutils-devel
Install wxWidgets (wxWidgets takes longer to compile)
$: cd /usr/local/wxGTK-2.8.12
// enable-shared=yes 表示设置为公共库
$: ./configure --enable-shared=no --enable-unicode=yes
$: make
$: sudo make install
Seeing the following display indicates that the installation was successful:
Configure environment variables:
$: vi /etc/profile
// 添加以下内容
export PATH=/usr/local/wxGTK-2.8.12/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/wxGTK-2.8.12/lib:$LD_LIBRARY_PATH
$: source /etc/profile
Set its dynamic library directory:
$: cd /etc/ld.so.conf.d/
$: sudo touch wxWidgets.conf
$: sudo vi wxWidgets.conf
// 添加以下内容
/usr/local/lib
$: source /etc/profile
$: sudo ldconfig # 重新加载动态库配置信息
Restart the server:
$: reboot
4. Install pgAgent
$: cd /usr/local/pgAgent-3.4.0-Source
$: cmake ./
$: make && make install
(Reference picture) After cmake ./ is completed, as shown in the figure:
(Reference picture) After make && make install is completed, as shown in the figure:
Create the pgAgent database in postgresql:
$; psql -h 192.168.1.189 -d postgres -U postgres -p 5432
// 在postgresql中输入sql如下
create extension pgagent;
CREATE EXTENSION
5. Start pgAgent First create the log directory of pgAgent:
$: mkdir -p /data/pgdata/log
Start the pgAgent daemon:
# hostaddr输入postgresql的主机地址
# dbname输入postgresql的数据库名称
# port输入postgresql的端口号
# user输入postgresql的用户账号
# password输入postgresql的用户密码
$: pgagent -t 60 -l 2 hostaddr=192.168.1.189 dbname=postgres port=5432 user=postgres password=1234 -s /data/pgdata/log/pgagent.log
// 检查pgagent进程
$: ps -ef | grep pgagent
// 显示如下
root 15216 1 0 Nov30 ? 00:00:02 pgagent -t 60 -l 2 hostaddr=192.168.1.189 dbname=postgres port=5432 user=postgres password=1234 -s /data/pgdata/log/pgagent.log
6. Install pgAdmin4
