Zabbix4.0 for PostgreSQL (上篇)：基础环境的搭建部署

概述

Zabbix大家都很熟悉，一般的是使用MySQL作为存储库来使用的，而我看使用手册上是使用postgresql也是可以的，所以就做了一次基于pg的zabbix搭建测试，记录下来，分享给大家

Server端配置

配置PG环境

安装好pg，且在root和postgres下都配置好pg的环境变量，以供后续使用

在hba控制文件中直接加入这一行

host    zabbix          zabbix          192.168.0.0/24          trust
host    all             all             127.0.0.1/32            md5

配置apache

创建user

[root@Zabbix_GW_TEST opt]# adduser apache

准备好安装包并解压

[root@Zabbix_GW_TEST opt]# ls httpd-2.4.37.tar.gz 
httpd-2.4.37.tar.gz
[root@Zabbix_GW_TEST opt]# tar -xvzf httpd-2.4.37.tar.gz 

编译安装

执行编译命令

[root@Zabbix_GW_TEST httpd-2.4.37]# ./configure --prefix=/usr/local/apache  --enable-rewrite --enable-deflate --enable-expires --enable-headers --enable-modules=most --with-mpm=worker --enable-so

报错：

configure: error: APR not found.  Please read the documentation.

解决：

yum install apr
yum install apr-util-devel

报错：

configure: error: in `/opt/httpd-2.4.37':
configure: error: C compiler cannot create executables
See `config.log' for more details

解决：

yum install gcc

问题：

configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解决：

yum -y install pcre-devel

问题：

configure: error: mod_deflate has been requested but can not be built due to prerequisite failures

解决：

yum install  -y zlib-devel

以下画面说明编译成功

configure: summary of build options:

    Server Version: 2.4.37
    Install prefix: /usr/local/apache
    C compiler:     gcc -std=gnu99
    CFLAGS:           -pthread  
    CPPFLAGS:        -DLINUX -D_REENTRANT -D_GNU_SOURCE  
    LDFLAGS:           
    LIBS:             
    C preprocessor: gcc -E

继续安装

gmake
gmake install

安装成功之后安装目录也就生成文件了

[root@Zabbix_GW_TEST apache]# ls
bin  build  cgi-bin  conf  error  htdocs  icons  include  logs  man  manual  modules

建立脚本根目录

用来存放html信息

mkdir /home/www
chown -R apache:apache /home/www

配置运行参数

[root@nfs httpd-2.2.31]# vim /usr/local/apache/conf/httpd.conf

#监听port
Listen 80

#运营apache服务的用户及用户组，为apache
User apache
Group apache

#管理员的邮箱是 
ServerAdmin [email protected]

#配置脚本根目录
DocumentRoot "/home/www"

#配置
ServerName 127.0.0.1:80

    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    allow from all



    Options Indexes FollowSymLinks    
    AllowOverride None   
    Order allow,deny
    Allow from all

配置环境变量

添加一行环境变量到文件中

export PATH=/usr/local/apache/bin:$PATH
[root@Zabbix_GW_TEST apache]# source ~/.bash_profile
[root@Zabbix_GW_TEST apache]# which apachectl
/usr/local/apache/bin/apachectl

启动apache服务

apachectl start

顺便配置开机自动

vim /etc/rc.d/rc.local
/usr/local/apache/bin/apachectl start

至此，Apache配置完成

安装配置php

安装php依赖包

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz
./configure --prefix=/usr/local/libiconv
make
make install

准备好包并解压

 tar -xvzf php-5.5.38.tar.gz

编译

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-xmlrpc --with-openssl --with-zlib --with-freetype-dir --with-gd --with-jpeg-dir --with-png-dir --with-iconv=/usr/local/libiconv --enable-short-tags --enable-sockets --enable-soap --enable-mbstring --enable-static --enable-gd-native-ttf --with-curl --with-xsl --enable-ftp --with-libxml-dir  --with-pgsql=/usr/postgresql --enable-fpm --enable-bcmath --with-gettext

报错

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

The output of /usr/local/apache/bin/apxs follows:
./configure: /usr/local/apache/bin/apxs: /replace/with/path/to/perl/interpreter: bad interpreter: No such file or directory
configure: error: Aborting

解决：将apache的bin文件下的apxs文件第一行改为

#!/usr/bin/perl -w

报错：

configure: error: xml2-config not found. Please check your libxml2 installation

yum install libxml2-devel

报错

configure: error: Cannot find OpenSSL's 

yum install openssl openssl-devel

报错

configure: error: Please reinstall the libcurl distribution -
    easy.h should be in /include/curl/

yum install curl curl-devel

报错

configure: error: There is something wrong. Please check config.log for more information.

curl-devel-7.15.5-2.el5安装

报错

configure: error: jpeglib.h not found.

yum -y install libjpeg-devel

报错

configure: error: png.h not found.

yum install libpng libpng-devel

报错：

configure: error: freetype-config not found.

yum install freetype-devel

报错

configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

yum -y install libxslt libxslt-devel

显示如下，则编译完成

换一个思路的nginx搭建

概述

在apache配置解析php的操作种，遇到种种坑，Apache的配置不太熟悉，界面打不开php文件，理论上问题是出在Apache配置访问php上。但是我能力有限，解决不来，所以就换一个NGINX试试。

编译安装

上传解压，并编译。NGINX的编译相对简单，就不做详细记录

tar -xvzf nginx-1.6.0.tar.gz
cd nginx-1.6.0

./configure --prefix=/usr/local/nginx --without-http_memcached_module --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
make
make install

配置NGINX访问PHP

这个是NGINX的关键，因为zabbix的界面全部都是PHP语言写的，必须使用PHP软件才能解析应用

server {
			listen       80;
			server_name  localhost;
			
			
			location ~ \.(php|php5)?$ {
				root /data/html;
				fastcgi_pass 127.0.0.1:9000;
				fastcgi_index  index.php;
				fastcgi_param SCRIPT_FILENAME /data/html$fastcgi_script_name;
				include fastcgi_params;
			}
			
			
			location ~* ^.+\.(ico|gif|jpg|jpeg|png|html|css|htm|bmp|js|svg)$ {
				root  /data/html;
			}
		}

配置nginx.conf文件。增加两个location，第一个location增加的是站点的地址信息。第二个是增加解析各种图片样式的功能（因为在没有加的时候，我打开的zabbix界面全部都是只有文字，没有任何图片与样式，如下。原因就是PHP没有解析这些内容）

创建好站点目录

浏览器通过端口来访问服务器的文件，并用解析器解析，我们需要先准备好这些文件。zabbix的PHP文件是放在源码包里的，解压后就可以看到可以在上面的配置文件中可以看到我已经选择了/data/html

cp -r  /opt/zabbix-4.0.2/frontends/php/*   /data/html

注意赋权

启动nginx

把环境变量配置在root下

export PATH=/usr/local/nginx/sbin:$PATH

启动nginx,没有报错则启动成功，看监听端口和后台进程

[root@Zabbix_GW_TEST ~]# netstat -lnp|grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      25373/nginx: master 


[root@Zabbix_GW_TEST ~]# ps -ef|grep nginx
root     12817 10266  0 18:11 pts/1    00:00:00 grep --color=auto nginx
root     25373     1  0 01:21 ?        00:00:00 nginx: master process nginx
www      27717 25373  0 02:07 ?        00:00:00 nginx: worker process

Zabbix配置

用户环境配置好

用户

adduser zabbix

编译zabbix

编译

./configure --prefix=/usr/local/zabbix --enable-server --enable-proxy --enable-agent --enable-ipv6 --with-postgresql=/usr/local/pgsql/bin/pg_config --with-net-snmp --with-ssh2 --with-openipmi --with-ldap --with-libcurl --with-iconv

安装依赖

yum install net-snmp-devel
yum install libssh2-devel
yum install OpenIPMI-devel
yum install openldap-devel
yum install libevent-devel
yum install curl-devel

编译到此界面则安装成功

***********************************************************
*            Now run 'make install'                       *
*                                                         *
*            Thank you for using Zabbix!                  *
*                                  *
***********************************************************

执行make install

配置好环境变量

将此行写进配置文件中

PATH=/usr/local/zabbix/bin:/usr/local/zabbix/sbin:$PATH

创建zabbix 数据库

postgres=# create role zabbix login
postgres-# ;
CREATE ROLE
postgres=# \password zabbix
Enter new password: 
Enter it again: 
postgres=#  create database zabbix with template template0 encoding 'UTF8' ;
CREATE DATABASE
postgres=#  grant all on database zabbix to zabbix;
GRANT
postgres=# \q

导入zabbix数据

在源码下，有zabbix数据库的数据

cd /opt/zabbix-4.0.2/database/postgresql/
psql -Uzabbix -dzabbix -h127.0.0.1 -f schema.sql
psql -Uzabbix -dzabbix -h127.0.0.1 -f images.sql
psql -Uzabbix -dzabbix -h127.0.0.1 -f data.sql

配置zabbix_server参数

[root@Zabbix_GW_server ~]# vim /usr/local/zabbix/etc/zabbix_server.conf

#监听port
ListenPort=10051

#日志存放地点及大小
LogFile=/tmp/zabbix_server.log
LogFileSize=10

#pid文件存放地点
PidFile=/tmp/zabbix_server.pid

#下面几个参数是配置数据库连接参数
DBHost=127.0.0.1
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBPort=5432

#监听ip范围
ListenIP=0.0.0.0

#media types中使用script存放目录
AlertScriptsPath=/usr/local/zabbix/alertscripts

启动服务

zabbix_server

查看是否有错，就查看zabbix_server 的启动日志，如果有报错，按照报错修改。反正我安装的时候真的报错频出，经历过，懂得都懂

查看web界面

此时就可以通过web界面来访问zabbix了
输入地址

可以看到，配存在一些问题也还是需要修改的，不然的话无法安装

agent端配置

概述

agnet端就是被监控的数据库主机，也是需要做一些安装

创建用户

groupadd zabbix
useradd  -g  zabbix -s  /sbin/nologin  zabbix

编译安装

 ./configure --prefix=/usr/local/zabbix-agent --enable-agent
make install

无需指定其他的编译参数

修改配置文件

 vi /usr/local/zabbix-agent/etc/zabbix_agentd.conf
 
LogFile=/tmp/zabbix_agentd.log
Server=192.168.6.17/32
Hostname=Zabbix agent

配置到环境变量

PATH=/usr/local/zabbix-agent/bin:/usr/local/zabbix-agent/sbin:$PATH

启动zabbix_agent

直接运行zabbix_agent命令，查看日志，观察是否正常

至此

至此，zabbix的基本配置完成。后续还要配置监控等操作。后面慢慢再说
