zabbix基于docker安装

centos的版本

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

docker的安装

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

安装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

启动docker

#systemctl start docker

使用docker搭建zabbix

1 、先安装数据库mysql

docker run --name zabbix-mysql-server --hostname zabbix-mysql-server \
-e MYSQL_ROOT_PASSWORD="123456" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="123456" \
-e MYSQL_DATABASE="zabbix" \
-p 33061:3306 \
-d mysql:5.7 \
--character-set-server=utf8 --collation-server=utf8_bin 

2 、创建zabbix-server

docker run  --name zabbix-server-mysql --hostname zabbix-server-mysql \
--link zabbix-mysql-server:mysql \
-e DB_SERVER_HOST="mysql" \
-e MYSQL_USER="zabbix" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_PASSWORD="123456" \
-v /etc/localtime:/etc/localtime:ro \
-v /data/docker/zabbix/alertscripts:/usr/lib/zabbix/alertscripts \
-v /data/docker/zabbix/externalscripts:/usr/lib/zabbix/externalscripts \
-p 10051:10051 \
-d \
zabbix/zabbix-server-mysql 

 3 、安装web-nginx

安装zabbix-web-nginx
docker run --name zabbix-web-nginx-mysql --hostname zabbix-web-nginx-mysql \
--link zabbix-mysql-server:mysql \
--link zabbix-server-mysql:zabbix-server \
-e DB_SERVER_HOST="mysql" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="123456" \
-e MYSQL_DATABASE="zabbix" \
-e ZBX_SERVER_HOST="zabbix-server" \
-e PHP_TZ="Asia/Shanghai" \
-p 7000:80 \
-p 8443:443 \
-d \
zabbix/zabbix-web-nginx-mysql

查看docker镜像

# docker ps -s
CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                                         NAMES                                   SIZE

zabbix-server基于docker安装完毕！

关闭防火墙和selinux

访问：http://宿主机IP：7000

默认用户名：Admin

默认登陆ming

echo 1 > /proc/sys/net/ipv4/ip_forward   #容器内网络与外网通，在宿主机上要开启网络转换

ps：开启网络转换容器只能ping通宿主机，不能通外网，重启docker就OK

进入zabbix-server容器

# docker exec -it zabbix-server-mysql /bin/bash
bash-4.3# ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
64 bytes from 1.1.1.1: icmp_seq=1 ttl=127 time=197 ms
64 bytes from 1.1.1.1: icmp_seq=2 ttl=127 time=196 ms
ps:网络通外网
查看ipbash-4.3# ip -4 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
278: eth0@if279: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    inet 172.17.0.15/16 scope global eth0
       valid_lft forever preferred_lft forever

替换容器中的安装源

1、备份配置文件：
cp -a /etc/apk/repositories /etc/apk/repositories.bak
2、修改repositories文件，将http://dl-cdn.alpinelinux.org/替换成https://mirrors.huaweicloud.com/，可以参考如下命令：sed -i s@http://dl-cdn.alpinelinux.org/@https://mirrors.huaweicloud.com/@g /etc/apk/repositories
3、执行apk update更新索引，执行apk search xxx查询软件包，执行apk add xxx安装软件包

安装zabbix-agent 并配置

#rpm -ivh 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
 docker exec -it zabbix-server-mysql 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
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
278: eth0@if279: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:11:00:0f brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.15/16 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:acff:fe11:f/64 scope link 
       valid_lft forever preferred_lft forever
# vim /etc/zabbix/zabbix_agentd.conf
Server=172.17.0.15
UnsafeUserParameters=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf
# systemctl start zabbix-agent.service

注意：如果要对宿主机进行监控，请编辑宿主机的zabbix_agentd.conf，将Server地址，默认127.0.0.1，修改为docker-server容器地址，否则不通；如果是对其他主机的监控则使用docker-zabbix-server宿主机的IP。
