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
Error: Package: zabbix-server-mysql-4.0.-.el7.x86_64 (zabbix)
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
Installed:
zabbix-server-mysql.x86_64 :4.0.-.el7 Dependency Installed:
OpenIPMI-libs.x86_64 :2.0.-.el7 OpenIPMI-modalias.x86_64 :2.0.-.el7 iksemel.x86_64 :1.4-.el7.centos Complete!
[root@web5 yum.repos.d]# rpm -qa |grep zabbix
zabbix-server-mysql-4.0.-.el7.x86_64
zabbix-get-4.0.-.el7.x86_64
zabbix-release-4.0-.el7.noarch
zabbix-web-mysql-4.2.-.3alpha3.el7.noarch
zabbix-web-4.2.-.3alpha3.el7.noarch
[root@web5 yum.repos.d]#
然后看一下文档
[root@web5 yum.repos.d]# rpm -ql zabbix-server-mysql
/etc/logrotate.d/zabbix-server
/etc/zabbix/zabbix_server.conf
/usr/lib/systemd/system/zabbix-server.service

/usr/share/man/man8/zabbix_server..gz
/var/log/zabbix
/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-server
systemctl start mariadb
systemctl enable mariadb
[root@mysql1 /]# netstat -untlp | grep
tcp 0.0.0.0:3306 0.0.0.0:* LISTEN /mysqld
2.2、创建zabbix数据库及zabbix用户
CREATE DATABASE zabbix character set utf8 collate utf8_bin; GRANT all privileges ON *.* TO 'zabbix'@'%' IDENTIFIED BY 'admin123'; MariaDB [mysql]> flush privileges;
2.3、修改数据库root密码
[root@mysql1 /]# mysql
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is
Server version: 5.5.-MariaDB MariaDB Server Copyright (c) , , Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A Database changed
MariaDB [mysql]> update user set password=password('newpassword') where user='root';
Query OK, rows affected (0.01 sec)
Rows matched: Changed: Warnings: 0
MariaDB [mysql]> flush privileges;
测试web5-55 测试连接数据库
[root@web5 web]# vim index.php <?php
#echo ("");
$link=mysql_connect('192.168.216.56','zabbix','admin123');
if($link) echo "<h1>The database connection was successful!</h1>";
else echo "<h1>The database connection was Fail!!</h1>";
mysql_close();
# phpinfo();
?>
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
[root@web2 zabbix]# cat /etc/nginx/conf.d/default.conf
upstream php-cluster {
#server 127.0.0.1: max_fails= fail_timeout=10s; #首先注释本地得php-fpm
server 192.168.216.55:9000 max_fails=3 fail_timeout=10s;
} server {
listen ;
server_name 192.168.216.52;
index index.html index.htm index.phpi;
root /usr/share/zabbix; #更换web目，zabbix默认目录，测试无所事先用默认得吧
location / { root /usr/share/nginx/html;
} location ~.*\.php$ { fastcgi_pass php-cluster;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
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
### Option: DBHost
DBHost=192.168.216.56
### Option: DBName
# DBName=
DBName=zabbix
# DBUser=
DBUser=zabbix
### Option: DBPassword
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
display_errors
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。
display_errors = On
开启状态下，若出现错误，则报错，出现错误提示
dispaly_errors = Off
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
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 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
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
// :: [error] #: * open() "/usr/share/zabbix/styles/blue-theme.css" failed (: 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"
// :: [error] #: * open() "/usr/share/zabbix/js/browsers.js" failed (: 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"

// :: [error] #: * open() "/usr/share/zabbix/styles/blue-theme.css" failed (: 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
DocumentRoot "/zabbix"
<Directory "/zabbix">
AllowOverride None
# Allow open access:
Require all granted
</Directory>
<Directory "/zabbix">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:

#
# The Options directive is both complicated and important. Please see

# AllowOverride controls what directives may be placed in .htaccess files.

#

# Controls who can get stuff from this server.
#
Require all granted
</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
下面几步，请参考Centos7+lnmp+zabbix+分离mysql实验
总结，这个例子主要是试试看的心态，并没有向下做下去，下一篇只对zabbix---》mysql做分离实验。并介绍一些用法。谢谢
