zabbix5.0部署 and 监控docker容器状态 and 配置企业微信报警机器人

1.系统优化
hostnamectl set-hostname docker-zabbix-server
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
systemctl disable --now firewalld
2.安装阿里源
yum install -y vim wget net-tools telnet
mv /etc/yum.repos.d /etc/yum.repos.d.backup
mkdir -p /etc/yum.repos.d
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
安装zabbix源
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
清理缓存
yum clean all
yum makecache

yum install zabbix-server-mysql zabbix-agent2 zabbix_get -y
yum install centos-release-scl -y
vim /etc/yum.repos.d/zabbix.repo将[zabbix-frontend]下的 enabled 改为 1
安装 zabbix 前端和相关环境
yum install zabbix-web-mysql-scl zabbix-apache-conf-scl -y
安装mysql8.0.20版本
软件包下载地址：
先去网站下载
https://dev.mysql.com/downloads/mysql/
tar -xvf mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar
yum install mysql-community-{server,client,common,libs}-*
systemctl start mysqld
查询随机密码
cat /var/log/mysqld.log | grep password
mysql -uroot -p
set global validate_password.policy=LOW; 
alter user 'root'@'localhost' identified by 'admin123';
show variables like 'validate_password%';
配置可远程连接
create user 'root'@'%' identified with mysql_native_password by 'admin123'; 
grant all privileges on *.* to 'root'@'%' with grant option;
flush privileges;
创建zabbix用户
create database zabbix character set utf8 collate utf8_bin;
create user zabbix@localhost identified by 'admin123';
grant all privileges on zabbix.* to zabbix@localhost;
select user,host,plugin from user;
ALTER USER zabbix@localhost IDENTIFIED WITH mysql_native_password BY 'admin123';
flush privileges;
quit;
导入zabbix数据
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
修改 zabbix server 配置文件vi /etc/zabbix/zabbix_server.conf 里的数据库密码
DBPassword=password
修改 zabbix 的 php 配置文件vi /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf 里的时区，改成 Asia/Shanghai
php_value[date.timezone] = Asia/Shanghai
开机自启动
systemctl restart zabbix-server zabbix-agent2 httpd rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent2 httpd rh-php72-php-fpm
systemctl status zabbix-server zabbix-agent2 httpd rh-php72-php-fpm

使用浏览器访问http://ip/zabbix 即可访问 zabbix 的 web 页面

更新conf配置
[15:51:55root@zabbix-server-docker /etc/docker]#grep -Ev '^#|^$' /etc/zabbix/zabbix_server.conf

加权
sudo gpasswd -a ${USER} docker
sudo gpasswd -a zabbix docker
cat /etc/group | grep docker
sudo service docker restart

usermod -a -G root zabbix
usermod -a -G docker zabbix
systemctl restart zabbix-agent2

测试监控数据
zabbix_get -s '192.168.124.10' -p 10050 -k 'agent.ping'
zabbix_get -s '192.168.124.10' -p 10050 -k docker.info
