 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Success.

All done!

创建zabbix数据库
[root@server1 ~]# mysql -p
mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> create user zabbix@localhost identified by 'Yakexi+007';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all privileges on zabbix.* to zabbix@localhost;
Query OK, 0 rows affected (0.00 sec)

mysql> set global log_bin_trust_function_creators = 1;
Query OK, 0 rows affected (0.00 sec)

导入数据，数据量比较大，需要等待一下，不要中断
[root@server1 ~]# zcat /usr/share/doc/zabbix-server-mysql-5.0.31/create.sql.gz | mysql -uzabbix -pYakexi+007 zabbix
导入后再禁用数据库参数
[root@server1 ~]# mysql -p
mysql> set global log_bin_trust_function_creators = 0;
Query OK, 0 rows affected (0.00 sec)


配置zabbix server
[root@server1 ~]# vim /etc/zabbix/zabbix_server.conf
#只需修改数据库密码
DBPassword=Yakexi+007

配置zabbix前端
[root@server1 zabbix]# vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
#去掉此行的注释，并修改时区
php_value[date.timezone] = Asia/Shanghai

启动服务
[root@server1 zabbix]# systemctl enable --now zabbix-server zabbix-agent httpd rh-php72-php-fpm

访问前端：http://192.168.56.11/zabbix

（2）前端操作

cd /usr/share/zabbix/assets/fonts
[root@server1 fonts]# rm -f graphfont.ttf
[root@server1 fonts]# ln -s simkai.ttf graphfont.ttf

###2.添加agent###

（1）手动添加

①agent配置

从server1拷贝repo文件
[root@server1 yum.repos.d]# scp zabbix.repo server2:/etc/yum.repos.d/

server2编辑拷贝过去的文件，禁掉key认证
[root@server2 ~]# vim /etc/yum.repos.d/zabbix.repo
...
gegcheck=0
...
[root@server2 yum.repos.d]# yum install -y zabbix-agent
[root@server2 ~]# vim /etc/zabbix/zabbix_agentd.conf
...
Server=192.168.56.11
ServerActive=192.168.56.11
Hostname=server2

[root@server2 zabbix]# systemctl  enable --now zabbix-agent.service

[root@server2 ~]# netstat -antlp |grep :10050
tcp        0      0 0.0.0.0:10050           0.0.0.0:*               LISTEN      8336/zabbix_agentd

②server端配置

可用性变成绿色表示添加成功

（2）自动发现

①agent配置

从server2拷贝repo文件
[root@server1 yum.repos.d]# scp zabbix.repo server3:/etc/yum.repos.d/
[root@server3 yum.repos.d]# yum install -y zabbix-agent
[root@server3 ~]# vim /etc/zabbix/zabbix_agentd.conf
...
Server=192.168.56.11
ServerActive=192.168.56.11
Hostname=server3

[root@server3 zabbix]# systemctl  enable --now zabbix-agent.service

②server端配置

选择发现动作，并激活

选择自动发现，修改实际的网络地址段，并激活

（3）自动注册

先删除server3主机

停用自动发现规则

创建自动注册动作

agent端重启服务

（4）zabbix api

参考官方文档手册

https://www.zabbix.com/documentation/5.0/zh/manual/api

Zabbix API允许你以编程方式检索和修改Zabbix的配置，并提供对历史数据的访问。它广泛用于：
创建新的应用程序以使用Zabbix；
将Zabbix与第三方软件集成；
自动执行常规任务。

大多数API至少包含四种方法： get， create， update 和 delete ，分别是检索，创建，更新和删除数据，但是某些API提供一套完全不同的一组方法。

①获取身份验证

在访问Zabbix中的任何数据之前，你需要登录并获取身份验证令牌。这可以使用该 user.login 方法完成。让我们假设你想要以标准Zabbix Admin用户身份登录。然后，你的JSON请求将如下所示：

响应对象又包含以下属性：

jsonrpc - JSON-RPC协议的版本;
result - 请求返回的数据;
id - 相应请求的id

获取token
curl -s -X POST http://192.168.56.11/zabbix/api_jsonrpc.php -H 'Content-Type: application/json-rpc' -d '
{
    "jsonrpc": "2.0",
    "method": "user.login",
    "params": {
        "user": "Admin",
        "password": "zabbix"
    },
    "id": 1,
    "auth": null
}' | python -m json.tool

认证后获取的token值
{
    "id": 1,
    "jsonrpc": "2.0",
    "result": "2a1536963f6ba0eeed3d0c113b16dc50"
}

②检索主机

使用 host.get 方法检索所有已配置主机的ID，主机名和接口

检索主机
vim zabbix_api.sh
curl -s -X POST http://192.168.56.11/zabbix/api_jsonrpc.php -H 'Content-Type: application/json-rpc' -d '
{
    "jsonrpc": "2.0",
    "method": "host.get",
    "params": {
        "output": [
            "hostid",
            "host"
        ],
        "selectInterfaces": [
            "interfaceid",
            "ip"
        ]
    },
    "id": 2,
    "auth": "2a1536963f6ba0eeed3d0c113b16dc50"
}' | python -m json.tool

③删除主机

删除之前先将前端的自动注册动作禁用

根据hostid，将主机删除

删除主机
vim zabbix_api.sh
curl -s -X POST http://192.168.56.11/zabbix/api_jsonrpc.php -H 'Content-Type: application/json-rpc' -d '
{
    "jsonrpc": "2.0",
    "method": "host.delete",
    "params": [
        "10440"
    ],
    "id": 2,
    "auth": "2a1536963f6ba0eeed3d0c113b16dc50"
}' | python -m json.tool

④创建主机

查看主机群组的id

查看模板的id

创建主机
vim zabbix_api.sh
curl -s -X POST http://192.168.56.11/zabbix/api_jsonrpc.php -H 'Content-Type: application/json-rpc' -d '
{
    "jsonrpc": "2.0",
    "method": "host.create",
    "params": {
        "host": "server3",
        "interfaces": [
            {
                "type": 1,
                "main": 1,
                "useip": 1,
                "ip": "192.168.56.13",
                "dns": "",
                "port": "10050"
            }
        ],
        "groups": [
            {
                "groupid": "2"
            }
        ],
        "tags": [
            {
                "tag": "Host name",
                "value": "server3"
            }
        ],
        "templates": [
            {
                "templateid": "10001"
            }
        ]
    },
    "id": 2,
    "auth": "2a1536963f6ba0eeed3d0c113b16dc50"
}' | python -m json.tool

###3.Zabbix服务监控###

（1）nginx监控

①源码编译nginx

安装nginx
[root@server2 ~]# tar zxf nginx-1.23.3.tar.gz
[root@server2 ~]# cd nginx-1.23.3/
[root@server2 nginx-1.23.3]# yum install -y gcc make openssl-devel pcre-devel
[root@server2 nginx-1.23.3]# ./configure  --with-http_stub_status_module --with-http_ssl_module
[root@server2 nginx-1.23.3]# make && make install

[root@server2 nginx]# ln -s /usr/local/nginx/sbin/nginx  /usr/local/bin/

[root@server2 ~]# vim /usr/local/nginx/conf/nginx.conf
server {
        listen       80;
        server_name  localhost;
...
        location = /basic_status {
            stub_status;
        }
...

[root@server2 conf]# nginx
[root@server2 conf]# netstat -antlp|grep :80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      23962/nginx: master

[root@server2 conf]# curl  localhost/basic_status
Active connections: 1
server accepts handled requests
 3 3 3
Reading: 0 Writing: 1 Waiting: 0

源码编译三部曲

开启服务，nginx监听80端口。修改配置文件，添加新的模块

Nginx 的 stub_status 模块用于查看 Nginx 的基本状态信息。

②前端关联模块

在server端为主机关联nginx服务监控模板

稍作等待，监控数据就会出来

（2）MySQL监控

①添加模板

zabbix自带mysql模板

拷贝模板
[root@server1 ~]# cp /usr/share/doc/zabbix-agent-5.0.31/userparameter_mysql.conf /etc/zabbix/zabbix_agentd.d/

重启agent
[root@server1 zabbix_agentd.d]# systemctl  restart zabbix-agent.service
创建数据库连接用户
[root@server1 zabbix_agentd.d]# mysql -p
mysql> CREATE USER 'zbx_monitor'@'%' IDENTIFIED BY 'Yakexi+007';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT REPLICATION CLIENT,PROCESS,SHOW DATABASES,SHOW VIEW ON *.* TO 'zbx_monitor'@'%';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

创建数据库连接文件
[root@server1 ~]# mkdir /var/lib/zabbix/
[root@server1 ~]# vim /var/lib/zabbix/.my.cnf
[client]
user=zbx_monitor
password=Yakexi+007

②前端关联模块

（3）percona数据库模板

zabbix自带的mysql模板比较简单，所以推荐使用percona的数据库模板

①添加模板

[root@server1 ~]# rpm -ivh percona-zabbix-templates-1.1.8-1.noarch.rpm

[root@server1 scripts]# cd /var/lib/zabbix/percona/templates
[root@server1 templates]# cp userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/
[root@server1 templates]# systemctl  restart zabbix-agent.service

[root@server1 zabbix_agentd.d]# cd /var/lib/zabbix/percona/scripts/
[root@server1 scripts]# vim ss_get_mysql_stats.php
...
$mysql_user = 'root';
$mysql_pass = 'Yakexi+007';

测试脚本
[root@server1 scripts]# ln -s /opt/rh/rh-php72/root/usr/bin/php /usr/bin/php

[root@server1 scripts]#  /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh gg
20
有数据显示就表示正常

删除tmp下的缓存文件
[root@server1 tmp]# rm -f localhost-mysql_cacti_stats.txt

②前端编译模块

导入模板文件

主机关联模板

等待监控数据出来

只要/tmp生成缓存文件就表示成功

[root@server1 tmp]# ls localhost-mysql_cacti_stats.txt
localhost-mysql_cacti_stats.txt

###4.tomcat监控+java网关###

zabbix server通过Java网关（zabbix-java-gateway）监听tomcat：8888

（1） tomcat端

server3上安装java应用
[root@server3 ~]# yum install -y java-1.8.0-openjdk.x86_64
[root@server3 ~]# tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local/
[root@server3 ~]# cd /usr/local/
[root@server3 local]# ln -s apache-tomcat-7.0.37/ tomcat
[root@server3 local]# cd tomcat/
[root@server3 tomcat]# cd bin/
[root@server3 bin]# vim catalina.sh
...
CATALINA_OPTS='-Dcom.sun.management.jmxremote.port=8888
  -Dcom.sun.management.jmxremote.ssl=false
  -Dcom.sun.management.jmxremote.authenticate=false'

[root@server3 bin]# ./startup.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

[root@server3 bin]# netstat -antlp|grep :8888
tcp6       0      0 :::8888                 :::*                    LISTEN      8025/java

（2） zabbix server端

server---->jmx---->8888

安装zabbix-java-gateway
[root@server1 ~]# yum install -y zabbix-java-gateway
[root@server1 zabbix]# systemctl  enable --now zabbix-java-gateway.service
[root@server1 zabbix]# netstat -antlp|grep :10052
tcp6       0      0 :::10052                :::*                    LISTEN      15393/java

修改server配置
[root@server1 zabbix]# vim /etc/zabbix/zabbix_server.conf
...
JavaGateway=192.168.56.11
JavaGatewayPort=10052
StartJavaPollers=5

[root@server1 zabbix]# systemctl  restart zabbix-server.service

（3）前端配置

添加jmx接口

关联模板

###5.Zabbix告警###

使用睿象云告警平台
将睿象云告警平台与zabbix监控相结合

注册用户：https://caweb.aiops.com/

（1）告警平台部署

创建appkey

部署探针

部署探针
[root@server1 ~]# cd /usr/lib/zabbix/alertscripts
[root@server1 alertscripts]# tar xf ca_zabbix_release-4.0.1.tar.gz
[root@server1 alertscripts]# cd cloudalert/bin
[root@server1 bin]# ./install.sh 80521b7c-eb16-46d8-a0fd-6a621f4938e4

[root@server1 alertscripts]# chown zabbix.zabbix cloudalert/ -R

禁用其他的告警媒介，为了测试效果

配置通知策略

（2）测试

停止server2的agent服务

[root@server2 ~]# systemctl  stop zabbix-agent.service

等待片刻后会触发报警，并发送到外部告警平台

可以在告警平台查看到完整到处理流程

当问题被解决

问题解决后显示已解决，并发送给平台

处理流程中显示已解决

###6.Zabbix+proxy分布式监控###

server——>agent:10050

agent——>server:10051(性能更高，server端更轻松)

Zabbix proxy 可以代替 Zabbix server 收集性能和可用性数据，承担一些收集数据的负担，分担了 Zabbix server 的负荷。

此外，使用proxy是实现集中式和分布式监控的最简单方法，所有 agents 和 proxies 发送给一个 Zabbix server，从而集中收集所有数据。

Zabbix proxy 使用场景:

监控远程区域设备

监控本地网络不稳定区域

监控上千设备时,减轻 zabbix server 的负荷

简化分布式监控的维护

Zabbix proxy到 Zabbix server 只需要一条 tcp 连接，仅在防火墙上配置一条规则即可。编辑

agent 主动方式

新建proxy节点，删除server2 agent作为proxy节点
[root@server2 ~]# systemctl  disable --now zabbix-agent.service
[root@server2 ~]# hostnamectl set-hostname proxy
[root@proxy ~]# vim /etc/hosts
192.168.56.12   server2 proxy

安装proxy软件
[root@proxy ~]#  yum install zabbix-proxy-mysql

前端删除server2，server2作为proxy

server1作为server端

在server1上创建proxy数据库
[root@server1 ~]# mysql -p
mysql> create database zabbix_proxy character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> create user 'zabbix'@'%' identified by 'Yakexi+007';
Query OK, 0 rows affected (0.01 sec)

mysql> grant all privileges on zabbix_proxy.* to 'zabbix'@'%';
Query OK, 0 rows affected (0.00 sec)

修改server2配置

从proxy拷贝数据库文件
[root@proxy ~]# cd /usr/share/doc/zabbix-proxy-mysql-5.0.31/
[root@proxy zabbix-proxy-mysql-5.0.31]# scp schema.sql.gz server1:

导入proxy数据库
[root@server1 ~]# zcat schema.sql.gz | mysql -uzabbix -pYakexi+007 zabbix_proxy

修改proxy配置
[root@proxy ~]# vim /etc/zabbix/zabbix_proxy.conf 
Server=192.168.56.11				#指向zabbix_server
Hostname=proxy					#主机名

DBHost=192.168.56.11				#proxy数据库配置
DBName=zabbix_proxy
DBUser=zabbix
DBPassword=Yakexi+007

JavaGateway=192.168.56.11		#jmx配置
JavaGatewayPort=10052
StartJavaPollers=5

[root@proxy ~]# systemctl  restart zabbix-proxy.service

前端创建proxy

为主机配置代理，server3作为agent端

修改agent配置，指向proxy地址

[root@server3 ~]# vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.56.12
ServerActive=192.168.56.12

[root@server3 ~]# systemctl  restart zabbix-agent.service

查看日志，没有报错就表示成功
[root@server3 ~]# cat /var/log/zabbix/zabbix_agentd.log
