一、简介
1、由于zabbix是php得，所有lnmp环境这里测试用的上一个实验环境，请查看https://www.cnblogs.com/zhangxingeng/p/10330735.html ；
2、就是上一个例子得架构图加上zabbix，架构图如下；
3、系统环境CentOS Linux release 7.6.1810 (Core)；
4、zabbix4，就zabbix3来说，安装起来还是很简单得，这次测试zabbix4.0+
5、添加zabbix源；
yum install http://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
注意：如果不是使用这个源，出现如下这个报错那么请更换正确得源就能解决
1 Error: Package: zabbix-server-mysql-4.0.4-1.el7.x86_64 (zabbix)2 ???????????Requires: libiksemel.so.3()(64bit)
二、开始部署（由于动静分离架构，稍微麻烦些）
1、web5-55-php-fpm 部署zabbix动态内容
安装依赖，zabbix没有单独得包，安装zabbix-server-mysql即可
zabbix-server-mysql #主程序包及数据库文件
zabbix-web-mysql #
zabbix-get #为了便于agent端发起测试采集数据请求用得
iksemel
libiksemel Required for Jabber support.
fping Required for ICMP ping items.
yum install -y zabbix-server-mysql zabbix-web-mysql
yum install zabbix-get
1 Installed:2 ??zabbix-server-mysql.x86_64 0:4.0.4-1.el7 ????????????????????????????????????????????????????????????????????????3 4 Dependency Installed:5 ??OpenIPMI-libs.x86_64 0:2.0.23-2.el7 ?OpenIPMI-modalias.x86_64 0:2.0.23-2.el7 ?iksemel.x86_64 0:1.4-2.el7.centos 6 7 Complete!
1 [root@web5 yum.repos.d]# rpm -qa |grep zabbix2 zabbix-server-mysql-4.0.4-1.el7.x86_643 zabbix-get-4.0.4-1.el7.x86_644 zabbix-release-4.0-1.el7.noarch5 zabbix-web-mysql-4.2.0-0.3alpha3.el7.noarch6 zabbix-web-4.2.0-0.3alpha3.el7.noarch7 [root@web5 yum.repos.d]#
然后看一下文档
1 [root@web5 yum.repos.d]# rpm -ql zabbix-server-mysql ?2 /etc/logrotate.d/zabbix-server 3 /etc/zabbix/zabbix_server.conf 4 /usr/lib/systemd/system/zabbix-server.service 5 /usr/lib/tmpfiles.d/zabbix-server.conf 6 /usr/lib/zabbix/alertscripts 7 /usr/lib/zabbix/externalscripts 8 /usr/sbin/zabbix_server_mysql 9 /usr/share/doc/zabbix-server-mysql-4.0.410 /usr/share/doc/zabbix-server-mysql-4.0.4/AUTHORS11 /usr/share/doc/zabbix-server-mysql-4.0.4/COPYING12 /usr/share/doc/zabbix-server-mysql-4.0.4/ChangeLog13 /usr/share/doc/zabbix-server-mysql-4.0.4/NEWS14 /usr/share/doc/zabbix-server-mysql-4.0.4/README15 /usr/share/doc/zabbix-server-mysql-4.0.4/create.sql.gz #zabbix数据库sql脚本16 /usr/share/man/man8/zabbix_server.8.gz17 /var/log/zabbix18 /var/run/zabbix
2、初始化数据库
2.1、准备好数据库机器mysql1，ip-56
关闭selinux，firewall，安装数据库
yum install mariadb-embedded mariadb-libs mariadb-bench mariadb mariadb-sever
systemctl start mariadb
systemctl enable mariadb
1 [root@mysql1 /]# netstat -untlp | grep 33062 tcp ???????0 ?????0 0.0.0.0:3306 ???????????0.0.0.0:* ??????????????LISTEN ?????37059/mysqld ?????
2.2、创建zabbix数据库及zabbix用户
1 CREATE DATABASE zabbix character set utf8 collate utf8_bin; 2 3 GRANT all privileges ON *.* TO ‘zabbix‘@‘%‘ IDENTIFIED BY ‘admin123‘;4 5 MariaDB [mysql]> flush privileges;
2.3、修改数据库root密码
1 [root@mysql1 /]# mysql 2 Welcome to the MariaDB monitor. ?Commands end with ; or \g. 3 Your MariaDB connection id is 2 4 Server version: 5.5.60-MariaDB MariaDB Server 5 ?6 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. 7 ?8 Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. 9 10 MariaDB [(none)]> use mysql;11 Reading table information for completion of table and column names12 You can turn off this feature to get a quicker startup with -A13 14 Database changed15 MariaDB [mysql]> update user set password=password(‘newpassword‘) where user=‘root‘;16 Query OK, 4 rows affected (0.01 sec)17 Rows matched: 4 ?Changed: 4 ?Warnings: 0
MariaDB [mysql]> flush privileges;
测试web5-55 测试连接数据库
1 [root@web5 web]# vim index.php ?2 ?3 <?php 4 #echo ("55"); 5 $link=mysql_connect(‘192.168.216.56‘,‘zabbix‘,‘admin123‘); 6 if($link) echo "<h1>The database connection was successful!</h1>"; 7 else echo "<h1>The database connection was Fail!!</h1>"; 8 mysql_close(); 9 # ??????phpinfo();10 ?>2.4、解压缩zabbix数据库脚本，并发送到数据库服务器
gunzip /usr/share/doc/zabbix-server-mysql-4.0.4/create.sql.gz
cd /usr/share/doc/zabbix-server-mysql-4.0.4/
scp create.sql root@192.168.216.56:/
2.5、导入数据库
mysql -uroot zabbix < /create.sql -p
3、配置nginx
web2-52 -nginx，配置文件
1 [root@web2 zabbix]# cat /etc/nginx/conf.d/default.conf ?2 upstream php-cluster { 3 ????????#server 127.0.0.1:9000 max_fails=3 fail_timeout=10s; #首先注释本地得php-fpm 4 ????????server 192.168.216.55:9000 max_fails=3 fail_timeout=10s; 5 ????????} 6 ?7 server { 8 ????????listen 80; 9 ????????server_name 192.168.216.52;10 ????????index index.html index.htm index.phpi;11 ????????root /usr/share/zabbix; #更换web目，zabbix默认目录，测试无所事先用默认得吧
12 ????????location / {13 14 ????????????????root ?/usr/share/nginx/html; 15 ????????}16 17 ????????location ~.*\.php$ {18 19 ????????????????fastcgi_pass ???php-cluster;20 ????????????????fastcgi_index ??index.php;21 ????????????????fastcgi_param ??SCRIPT_FILENAME $document_root$fastcgi_script_name;22 ????????????????include ????????fastcgi_params;23 ????????}24 }4、配置zabbix
web5-55
4.1、修改zabbix配置
vim /etc/zabbix/zabbix_server.conf
修改下面几项即可
1 ### Option: DBHost2 DBHost=192.168.216.563 ### Option: DBName4 # DBName=5 DBName=zabbix6 # DBUser=7 DBUser=zabbix8 ### Option: DBPassword9 DBPassword=admin123
systemctl start zabbix-server
4.2、解决error问题
测试访问www.web1.com/index.php，报错500，网上查询说display_errors没配置得原因，这里可以设置成on
问题1、网页返回500错误码，修改display_errors
web5-55
vim /etc/php.ini
display_errors = On
systemctl restart php-fpm
1 display_errors 2 错误回显，一般常用语开发模式，但是很多应用在正式环境中也忘记了关闭此选项。错误回显可以暴露出非常多的敏感信息，为攻击者下一步攻击提供便利。推荐关闭此选项。 3 display_errors = On 4 开启状态下，若出现错误，则报错，出现错误提示 5 dispaly_errors = Off 6 关闭状态下，若出现错误，则提示：服务器错误。但是不会出现错误提示
问题2、269的warning，给权限
再次访问www.web1.com/index.php,发现是269得warning，因为是nginx启动得php-fpm我们可以给一下权限
1 Warning: require_once(/etc/zabbix/web/maintenance.inc.php): failed to open stream: Permission denied in /usr/share/zabbix/include/classes/core/ZBase.php on line 269 Fatal error: require_once(): Failed opening required ‘/etc/zabbix/web/maintenance.inc.php‘ (include_path=‘.:‘) in /usr/share/zabbix/include/classes/core/ZBase.php on line 269
chown nginx:nginx -R /etc/zabbix
chown nginx:nginx -R /usr/share/zabbix
chmod 755 -R /etc/zabbix
chmod 755 -R /usr/share/zabbix
问题3、没有图片效果，因为架构是动静分离，所以静态内容需要放到静态服务器上
先访问一下，什么鬼，文字模式，没有图片效果
我们先用访问192.168.216.52/index.php,效果一样，也是文字模式，那我们看一下nginx的error.log
tail -5 /var/log/nginx/error.log
1 2019/02/20 18:37:45 [error] 3595#0: *8 open() "/usr/share/zabbix/styles/blue-theme.css" failed (2: No such file or directory), client: 192.168.216.1, server: 192.168.216.52, request: "GET /styles/blue-theme.css HTTP/1.1", host: "192.168.216.52", referrer: "http://192.168.216.52/setup.php"2 2019/02/20 18:37:45 [error] 3595#0: *9 open() "/usr/share/zabbix/js/browsers.js" failed (2: No such file or directory), client: 192.168.216.1, server: 192.168.216.52, request: "GET /js/browsers.js HTTP/1.1", host: "192.168.216.52", referrer: "http://192.168.216.52/setup.php"3 2019/02/20 18:37:47 [error] 3595#0: *9 open() "/usr/share/zabbix/js/browsers.js" failed (2: No such file or directory), client: 192.168.216.1, server: 192.168.216.52, request: "GET /js/browsers.js HTTP/1.1", host: "192.168.216.52", referrer: "http://192.168.216.52/setup.php"4 2019/02/20 18:37:47 [error] 3594#0: *11 open() "/usr/share/zabbix/styles/blue-theme.css" failed (2: No such file or directory), client: 192.168.216.1, server: 192.168.216.52, request: "GET /styles/blue-theme.css HTTP/1.1", host: "192.168.216.52", referrer: "http://192.168.216.52/setup.php"
提示没有找到/usr/share/zabbix/styles,/usr/share/zabbix/js,提示找不到这两个目录，我们把目录复制过来，看看，为了方便可以先把所有目录一起复制过来
web5
cd /usr/share/
tar -jcvf zabbix.tar.bz2 zabbix
scp zabbix.tar.bz2 root@192.168.216.52:/
web2
cd /
tar -jxvf zabbix.tar.bz2
完成在访问一下，成功
那么放在 httpd服务器的效果那
web5-55
scp zabbix.tar.bz2 root@192.168.216.54:/
web4-54
cd /
tar -jxvf zabbix.tar.bz2
chown -R apache:apache zabbix
vim /etc/httpd/conf/httpd.conf
1 DocumentRoot "/zabbix" 2 <Directory "/zabbix"> 3 AllowOverride None 4 # Allow open access: 5 Require all granted 6 </Directory> 7 <Directory "/zabbix"> 8 ????# 9 ????# Possible values for the Options directive are "None", "All",10 ????# or any combination of:11 ????# ??Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews12 ????#13 ????# Note that "MultiViews" must be named *explicitly* --- "Options All"14 ????# doesn‘t give it to you.15 ????#16 ????# The Options directive is both complicated and important. ?Please see17 ????# http://httpd.apache.org/docs/2.4/mod/core.html#options18 ????# for more information.19 ????#20 ????Options Indexes FollowSymLinks21 22 ????#23 ????# AllowOverride controls what directives may be placed in .htaccess files.24 ????# It can be "All", "None", or any combination of the keywords:25 ????# ??Options FileInfo AuthConfig Limit26 ????#27 ????AllowOverride None28 29 ????#30 ????# Controls who can get stuff from this server.31 ????#32 ????Require all granted33 </Directory>
systemctl restart httpd
访问一下www.web1.com/index.php
三、开始配置zabbix
1、welcome，进入zabbix界面我们开始部署，点next
2、check of pre-requisites
编辑解决这三个问题
web5
vim /etc/php.ini
post_max_size = 16M # PHP将接受的POST数据的最大大小
max_execution_time = 300 #每个脚本最大执行时间
max_input_time = 300 #每个脚本可能花费在解析请求数据上的最大时间
systemctl restart php-fpm
刷新网页
3、configure DB connect
4、zabbix server details
5、pre-installation summary
6、insatll
总结，这个例子主要是试试看的心态，并没有向下做下去，因为还有很多问题，需要很多精力，下一篇只对zabbix---》mysql做分离实验。并介绍一些用法。谢谢
