基於docker部署zabbix

基礎環境

cat /etc/redhat-release 
CentOS Linux release 7.5.1804 (Core)

docker安裝

配置yum源

# vim /etc/yum.repos.d/docker-ce.repo
[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/7/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg

安裝docker-ce

# wget https://mirrors.aliyun.com/centos-vault/7.3.1611/extras/x86_64/Packages/container-selinux-2.9-4.el7.noarch.rpm
# yum localinstall container-selinux-2.9-4.el7.noarch.rpm -y
# yum install docker-ce -y

更換源

順便把docker源也換一下吧，省得一會還的重啓

# vim /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}

啓動docker，查看版本號

# systemctl start docker.service

# docker version

docker安裝完畢！

開啓網絡轉換

#echo 1 > /proc/sys/net/ipv4/ip_forward   #網絡重啓會後要從新開啓

用Dockerfile部署

zabbix-server部署階段

要用docker跑zabbix-server，須要如下幾個組件

組件名稱	做用
數據庫	MySQL或是PostgreSQL
Zabbix Java gateway	Java管理擴展，能夠不添加
Zabbix server	zabbix 服務端
zabbix-web	與MySQL服務器實例和Zabbix server實例關聯
zabbix-agent	zabbix客戶端

MySQL數據庫

數據庫我選擇MySQL，仍是得寫Dockerfile，改一下時區，時間不對很麻煩，字符集也改一下吧

# mkdir /data/docker/mysql -p
/data/docker/mysql]# vim Dockerfile
FROM mysql:5.7
ENV LANG en_US.utf8
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo Asia/Shanghai > /etc/timezone \

構建鏡像

#docker build -t debian-mysql5.7 .  # docker images REPOSITORY TAG IMAGE ID CREATED SIZE debian-mysql5.7 latest 3d3c7dc9608c 14 seconds ago 372MB mysql 5.7 563a026a1511 3 weeks ago 372MB

啓動容器

# docker run --hostname mysql --name debian-mysql-5.7 -t \
 -e MYSQL_USER="zabbix" \
 -e MYSQL_DATABASE="zabbix" \
 -e MYSQL_PASSWORD="passwd" \
 -e MYSQL_ROOT_PASSWORD="passwd" \
 -v /data/mysql:/var/lib/mysql:rw \
 -d debian-mysql5.7
9a98a2ba0896a8a146d515764d2d8eef4bc32a9f0dbea445c360fab5668a5cfe
# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
9a98a2ba0896        debian-mysql5.7     "docker-entrypoint.s…

變量說明

變量
MYSQL_USER	啓動時要添加的用戶
MYSQL_DATABASE	啓動時要建立的數據庫
MYSQL_PASSWORD	指定添加用的的密碼
MYSQL_ROOT_PASSWORD	root用戶的密碼

Zabbix Java gateway

這個看我的，若是不監控java應用服務器能夠不安裝這個，仍是得寫Dockerfile，改一下時區和編碼。

/data/docker/java-gateway]# cat Dockerfile 
FROM zabbix/zabbix-java-gateway:latest
ENV LANG en_US.utf8
RUN apk add -U tzdata
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo Asia/Shanghai > /etc/timezone \
 /data/docker/java-gateway]# docker build -t zabbix-java-gateway .
 /data/docker/java-gateway]# docker images
REPOSITORY                   TAG                 IMAGE ID            CREATED             SIZE
zabbix-java-gateway          latest              7948dffa9af0        35 seconds ago      80.1MB

啓動容器

須要映射一下10052端口

# docker run --hostname zabbix-java-gateway \
 -name zabbix-java-gateway -t \
 -p 10052:10052 \
 -d zabbix-java-gateway 
5e2434e7a4c6f3f947e6408ff5a90097e802c6a36282c36ce7e4cd5819474f7a
# docker ps

Zabbix server 

編寫Dockerfile

 /data/docker/zabbix-server]# cat Dockerfile 
FROM zabbix/zabbix-server-mysql:latest
ENV LANG en_US.utf8
RUN apk add -U tzdata
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo Asia/Shanghai > /etc/timezone \
/data/docker/zabbix-server]# docker build -t zabbix-server .
/data/docker/zabbix-server]# docker images
REPOSITORY                   TAG                 IMAGE ID            CREATED              SIZE
zabbix-server                latest              531aa3116f61        About a minute ago   62.3MB

須要映射10051端口，指定數據庫服務器，鏈接MySQL和zabbix-java-gateway容器

10051:10051 \
--hostname zabbix-server \
-e DB_SERVER_HOST="debian-mysql-5.7" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="passwd" \
-e MYSQL_ROOT_PASSWORD="passwd" \
-e ZBX_JAVAGATEWAY="zabbix-java-gateway" \
--link debian-mysql-5.7:mysql \
--link zabbix-java-gateway:zabbix-java-gateway \
-d zabbix-server
# docker ps

a45ef352cc68 zabbix-server "docker-entrypoint.sh" 9 minutes ago Up 8 minutes 0.0.0.0:10051->10051/tcp zabbix-server

zabbix-web

編寫Dockerfile

/data/docker/zabbix-web]# cat Dockerfile 
FROM zabbix/zabbix-web-nginx-mysql:latest
ENV LANG en_US.utf8
RUN apk add -U tzdata
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo Asia/Shanghai > /etc/timezone \
 /data/docker/zabbix-web]# docker build -t zabbix-web .
 /data/docker/zabbix-web]# docker images
REPOSITORY                      TAG                 IMAGE ID            CREATED              SIZE
zabbix-web                      latest              6ff51e2f0545        About a minute ago   164MB

啓動容器

 須要映射80端口到宿主機，鏈接數據庫，鏈接zabbix-server容器

# docker run --name zabbix-web -t \
 -p 80:80 \
 --hostname zabbix-web \
 -e PHP_TZ="Asia/Shanghai" \
 -e DB_SERVER_HOST="debian-mysql-5.7" \
 -e MYSQL_DATABASE="zabbix" \
 -e MYSQL_USER="zabbix" \
 -e MYSQL_PASSWORD="passwd" \
 -e MYSQL_ROOT_PASSWORD="passwd" \
 --link debian-mysql-5.7:mysql \
 --link zabbix-server:zabbix-server \

f0c33f227992ce220730da9454df2f354565ed0b3d0813513a87797c2b752702
# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                         NAMES
f0c33f227992        zabbix-web            "docker-entrypoint.sh"   13 seconds ago      Up 10 seconds       0.0.0.0:80->80/tcp, 443/tcp   zabbix-web

以上方式安裝的是最新版本，由於在指定鏡像的時候沒有指定版本號，默認的就是laster，也就是最新版本，建議zabbix-agent版本要和服務端一致。

看下安裝的容器

# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                         NAMES

/tcp, 33060/tcp           debian-mysql-5.

訪問：http://宿主機IP：80

zabbix-agent

安裝（用官方yum源）

#rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
#yum -y install zabbix-agent-4.0.1

#vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.130.6
UnsafeUserParameters=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf
# systemctl start zabbix-agent

注意：若是要對宿主機進行監控，請編輯宿主機的zabbix_agentd.conf，將Server地址，默認127.0.0.1，修改成docker-server容器地址，不然不通；若是是對其餘主機的監控則使用docker-zabbix-server宿主機的IP。

查看容器Zabbix-server的地址

# docker exec -it zabbix-server ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
23: eth0@if24: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:11:00:04 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.4/16 brd 172.17.255.255 scope global eth0
       valid_lft forever preferred_lft forever

使用docker-compose

docker-compose去作，該鏡像版本爲4.0.1

安裝docker-compose

# curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
# docker-compose --version
docker-compose version 1.23.1, build b02f1306

編寫zabbix.yml

這個已是寫好的，拿過去直接用吧，image不要動，其餘的看本身狀況自行調整吧

# mkdir /docker-compose
# cd /docker-compose/
/docker-compose]# vim zabbix.yml

訪問：http://宿主機IP：80

網頁端操做

直接編輯名爲zabbix server的主機，Agent interfaces改成宿主機內網IP，而後update，我順便又手動加了個主機進來，監控別的主機server地址直接寫zabbix server宿主機便可。

郵件報警

以nginx down 爲例前面博客有具體操做，這就再也不贅述。

郵件設置

點開Administration→Media types→Email編輯，以使qq郵箱爲例，163郵箱收不到。

添加收件人

接下來去Configuration→actions，選擇Triggers，添加觸發條件，能夠有多個，我添加的是時間段和觸發器。

在Acrion裏添加動做—>operations

測試

手動停掉nginx
