手把手教你如何通过docker-compose部署Zabbix监控

软件环境部署

一、部署docker-ce版本以及pip工具，并安装docker-compose工具

#yum install -y docker-ce python36-setuptools  python36-pip 
#pip3 install docker-compose==1.23.2

二、编写docker-compose的yaml文件

version: '3.7'
services:
 zabbix-server:
  image: docker-registry.hexun.com/system_ops/zabbix-server-mysql:centos-4.0-latest
  ports:

三、编写各个容器对应的env_file环境变量文件

3.1：编写mysql对应env_file文件

#vim /data/zabbix-system/zabbix-apps/.env_db_mysql 

# DB_SERVER_HOST=mysql-server
# DB_SERVER_PORT=3306
# MYSQL_USER=zabbix
MYSQL_USER=zabbix
# MYSQL_PASSWORD=zabbix
MYSQL_PASSWORD=4Z8tQ5hbXIxR4be
# MYSQL_ROOT_PASSWORD=
MYSQL_ROOT_PASSWORD=4Z8tQ5hbXIxR4be
# MYSQL_ALLOW_EMPTY_PASSWORD=false
# MYSQL_DATABASE=zabbix
MYSQL_DATABASE=zabbix

#增大最大连接数
#show variables like 'max_connections';(查可以看当前的最大连接数)
#
# set global max_connections=1000;
# max_connections=1500
# innodb_buffer_pool_instances=5
# innodb_buffer_pool_size=6G
# key_buffer_size=6G

 3.2: 设置zabbix-server容器的env_file环境变量

# vim /data/zabbix-system/zabbix-apps/.env_srv

ZBX_LISTENIP=127.0.0.1
ZBX_STARTPOLLERS=30
ZBX_IPMIPOLLERS=1
ZBX_STARTPREPROCESSORS=30
ZBX_STARTPOLLERSUNREACHABLE=30
ZBX_STARTTRAPPERS=30
ZBX_STARTPINGERS=20
ZBX_STARTDISCOVERERS=20
ZBX_STARTHTTPPOLLERS=20
ZBX_STARTTIMERS=20
ZBX_STARTESCALATORS=30
ZBX_STARTALERTERS=20
ZBX_JAVAGATEWAY_ENABLE=true
ZBX_JAVAGATEWAY=zabbix-java-gateway
ZBX_JAVAGATEWAYPORT=10052
ZBX_STARTJAVAPOLLERS=1
ZBX_STARTVMWARECOLLECTORS=1
ZBX_VMWAREFREQUENCY=50
ZBX_VMWAREPERFFREQUENCY=60
ZBX_VMWARECACHESIZE=80M
ZBX_VMWARETIMEOUT=10
ZBX_ENABLE_SNMP_TRAPS=true
ZBX_HOUSEKEEPINGFREQUENCY=6
ZBX_MAXHOUSEKEEPERDELETE=200000
ZBX_SENDERFREQUENCY=30
ZBX_CACHESIZE=4024M
ZBX_CACHEUPDATEFREQUENCY=60
ZBX_STARTDBSYNCERS=30
ZBX_HISTORYCACHESIZE=2048M
ZBX_HISTORYINDEXCACHESIZE=888M
ZBX_TRENDCACHESIZE=888M
ZBX_VALUECACHESIZE=4096M
ZBX_TIMEOUT=30
ZBX_TRAPPERIMEOUT=300
ZBX_UNREACHABLEPERIOD=45
ZBX_UNAVAILABLEDELAY=60
ZBX_UNREACHABLEDELAY=1
ZBX_LOGSLOWQUERIES=3000
ZBX_STARTPROXYPOLLERS=20
ZBX_PROXYCONFIGFREQUENCY=600
ZBX_PROXYDATAFREQUENCY=1

3.3:设置Nginx-web容器的env_file环境变量

#vim /data/zabbix-system/zabbix-apps/.env_web

ZBX_SERVER_HOST=192.168.60.100
ZBX_SERVER_PORT=10051
ZBX_SERVER_NAME=tjdl-zabix-server
ZBX_MAXEXECUTIONTIME=600
ZBX_MEMORYLIMIT=512M
ZBX_POSTMAXSIZE=50M
ZBX_UPLOADMAXFILESIZE=2M
ZBX_MAXINPUTTIME=300
ZBX_SESSION_NAME=zbx_sessionid
PHP_TZ=Asia/Shanghai

3.4: 设置java-gateway容器环境变量

# vim /data/zabbix-system/zabbix-apps/.env_java

ZBX_START_POLLERS=5
ZBX_TIMEOUT=3
# Possible values: trace, debug, info, want, error, all, off
ZBX_DEBUGLEVEL=info

以上编写好yaml文件以及环境变量，可尝试重启各个容器服务组件，

[root@hostname-60100 zabbix-apps]#docker-compose -f zabbix-apps-compose.yaml up -d#创建容器并启动
WARNING: Some services (mysql-server, zabbix-java-gateway, zabbix-server, zabbix-snmptraps, zabbix-web-nginx-mysql) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.
Restarting zabbix-apps_zabbix-web-nginx-mysql_1 ... done
Restarting zabbix-apps_zabbix-server_1          ... done
Restarting zabbix-apps_mysql-server_1           ... done
Restarting zabbix-apps_zabbix-snmptraps_1       ... done
Restarting zabbix-apps_db_data_mysql_1          ... done
Restarting zabbix-apps_zabbix-java-gateway_1    ... done

检查一下docker容器是否都正常启动，如果有容器无法正常启动，可查看某个容器日志进行排错，例如下面的zabbix-server没有启动，为退出状态

报错：connenction to database 'zabbix' failed: too many connections

 docker-compose -f zabbix-apps-compose.yaml logs -f  zabbix-server  #查看容器日志

# docker exec -it zabbix-apps_mysql-server_1 bash  可进入mysql容器设置默认最大连接数

root@fdbebd4882df:/# egrep -v "#|^$" etc/mysql/mysql.conf.d/mysqld.cnf  #增加max_connections=1000参数，修改配置文件之后需重启mysql服务，因为mysql已经容器化，需要重启生效即可
[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
symbolic-links=0
max_connections=1000

Ps:还有一种方法可以在mysql命令行中设置最大连接数，但只是临时生效（set global max_connections=1000；）

mysql> show variables like 'max_connections';  #查看mysql最大连接数；
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 1000 |
+-----------------+-------+
1 row in set (0.00 sec)

最后再次查看zabbix-server容器日志，已经没有异常信息提示

#docker-compose -f zabbix-apps-compose.yaml logs -ft  zabbix-server  

 四：进入lnmp容器修改php对应的配置文件

 #docker exec -it zabbix-apps_zabbix-web-nginx-mysql_1 bash

#cat  /usr/share/zabbix/conf/zabbix.conf.php   #注意这里的php配置文件一定要与前面之前编写的.env_srv环境内容对应
<?php
// Zabbix GUI configuration file.
global $DB, $HISTORY;

$DB['TYPE']     = 'MYSQL';
$DB['SERVER']   = 'mysql-server';
$DB['PORT']     = '3306';
$DB['DATABASE'] = 'zabbix';
$DB['USER']     = 'zabbix';
$DB['PASSWORD'] = '4Z8tQ5hbXIxR4be';

// Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = '';

$ZBX_SERVER      = '192.168.60.100';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = 'tjdl-zabix-server';

$IMAGE_FORMAT_DEFAULT    = IMAGE_FORMAT_PNG;

// Elasticsearch url (can be string if same url is used for all types).
$HISTORY['url']   = '';
// Value types stored in Elasticsearch.
$HISTORY['types'] = [];

当一切配置修改完毕之后，再次通过docker-compose启动各个容器组件，确保每个配置均已生效

 docker-compose -f zabbix-apps-compose.yaml restart

 访问zabbix监控url：http://192.168.60.100/zabbix.php?action=dashboard.view

五、更新本地agent端配置：

 #docker inspect zabbix-apps_zabbix-server_1 | grep -i ipaddr  #查看zabbix-server容器的IP地址，此IP用于agent配置文件中的server地址
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "172.18.0.2",  

agent配置文件如下：

[root@hostname-60100 zabbix-apps]# egrep -v "#|^$" /etc/zabbix/zabbix_agentd.conf
PidFile=/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=172.18.0.2
ListenIP=192.168.60.100
Include=/etc/zabbix/zabbix_agentd.d/*.conf1

#systemctl restart zabbix-agent #重启zabbix-agent

如果agent端监控成功，那么zabbixserver端获取的图形式乱码状态，需要中文乱码问题

、

  #docker cp DejaVuSans.ttf zabbix-apps_zabbix-web-nginx-mysql_1:/usr/share/zabbix/assets/fonts/  #将windows下的中文字体拷贝到web容器相应的目录中，最后重启容器刷新即可

  #docker-compose -f zabbix-apps-compose.yaml restart zabbix-web-nginx-mysql

 END!
