pgagent 作为postgresql的一个任务调度代理，在postgresql 9.0 以前 是附带在pgadmin 包下面的，只是默认不安装，9.0之后作为了一个单独是的安装包。所以要使用pgagent定时任务调度的话还得单独安装。
在安装pgagent之前还需要安装另外的2个依赖包，cmake 以及wxGTK.
这里我选择的软件版本分别是
postgresql 9.5.1
pgagent-3.4.0下载地址：https://www.pgadmin.org/download/pgagent.php
cmake-2.8.5 下载地址：http://cmake.org/download/
wxGTK-2.8.12 下载地址：http://www.wxwidgets.org/downloads/
一、postgresql 的安装
（略）
二、cmake的安装
将安装包上传至服务器并解压，解压后进入解压后生成的cmake-2.8.5目录，执行以下命令。
[root@lsrac97 ~]# tar zxvf pgagent-3.4.0.tar.gz
[root@lsrac97 ~]# cd cmake-2.8.5
[root@lsrac97 cmake-2.8.5]# ./bootstrap && make && make install
三、wxGTK-2.8.12 的安装
首先配置.bash_profile参数文件
[root@lsrac97 ~]#vi .bash_profile
#加入以下内容：PATH=$PATH:$HOME/bin:/usr/local/wxGTK-2.8.12/bin
export LD_LIBRARY_PATH=/usr/local/wxGTK-2.8.12/lib:$LD_LIBRARY_PATH
#并生效参数文件，命令如下：
[root@lsrac97 ~]#source .bash_profile
接着解压该安装包并进入其目录，然后编译和安装
[root@lsrac97 wxGTK-2.8.12 ]# ./configure –enable-shared=no –enable-unicode=yes –prefix=/usr/local/wxGTK-2.8.12
[root@lsrac97 wxGTK-2.8.12 ]# make && make install
四、pgagent的安装
上传安装包至服务器并解压,进入目录执行如下命令：
[root@lsrac97 pgAgent-3.4.0-Source]# cmake ./
提示报错：没有安装postgresql
CMake Error at cmake/FindPG.cmake:131 (MESSAGE):
No PostgreSQL installation could be found.
Call Stack (most recent call first):
CMakeLists.txt:107 (FIND_PACKAGE)
这里需要先指定postgresql环境变量
[root@lsrac97 pgAgent-3.4.0-Source]# source /home/postgres/.bash_profile
[root@lsrac97 pgAgent-3.4.0-Source]# cmake ./

进入数据库中，执行create extension pgagent;即可。
postgres=# create extension pgagent ;
CREATE EXTENSION如此pgagent扩展安装完成。
下面是其中遇到的问题：
安装wxWidGets报错：

configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent. 解决：
需要安装gtk2-devel和binutils
yum -y install gtk2-devel binutils-devel
然后wxWidGets继续安装即可。
