Zabbix集中监控系统

一、概述
Zabbix是一个高度集成的企业级开源网络监控解决方案。提供分布式监控以及集中的Web管理界面，被监控对象只要支持SNMP协议或者运行zabbix代理程序即可。
功能包括主机性能监控、网络设备性能监控、数据库性能监控、FTP等协议的监控，能够利用灵活的可制定警告机制，允许用户对事件发送警告。
二、安装配置
1、源码编译安装
可参考https://www.cnblogs.com/uglyliu/p/10143914.html的安装脚本，具体代码如下：

#!/bin/bash
#安装zabbix4.0脚本
err_echo(){
    echo -e "\033[41;37m[Error]: $1 \033[0m"
    exit 1
}

info_echo(){
    echo -e "\033[42;37m[Info]: $1 \033[0m"
}

check_file_is_exists(){
    if [ ! -f "/usr/local/src/$1" ];then
        info_echo "$1开始下载"
    fi
}

check_exit(){
    if [ $? -ne 0 ]; then
        err_echo "$1"
        exit 1
    fi
}

check_success(){
    if [ $? -eq 0 ];then
        info_echo "$1"
    fi
}

[ $(id -u) != "0" ] && err_echo "please run this script as root user." && exit 1

2、Docker容器安装

#agent容器,ZBX_SERVER_HOST如果是server机，需填写server容器IP，其他agent填写server母机IP
docker run --name zabbix-agent \
-p 10050:10050 \
-e ZBX_HOSTNAME="zabbix-server" \
-e ZBX_SERVER_HOST="zabbix-server-mysql" \
-e ZBX_SERVER_PORT=10051 \
--link zabbix-server-mysql:zabbix-server-mysql \
-d zabbix/zabbix-agent

#server容器
docker run --name mysql-server -t \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix_pwd" \
-e MYSQL_ROOT_PASSWORD="root_pwd" \
-d mysql:8.0 \
--character-set-server=utf8 --collation-server=utf8_bin \
--default-authentication-plugin=mysql_native_password

#java容器
docker run --name zabbix-java-gateway -t \
--restart unless-stopped \
-d zabbix/zabbix-java-gateway:latest

#mysql容器
docker run --name zabbix-server-mysql -t \
-e DB_SERVER_HOST="mysql-server" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix_pwd" \
-e MYSQL_ROOT_PASSWORD="root_pwd" \
-e ZBX_JAVAGATEWAY="zabbix-java-gateway" \
--link mysql-server:mysql \
--link zabbix-java-gateway:zabbix-java-gateway \
-p 10051:10051 \
--restart unless-stopped \
-d zabbix/zabbix-server-mysql:latest

#web容器
docker run --name zabbix-web-nginx-mysql -t \
-e DB_SERVER_HOST="mysql-server" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="zabbix_pwd" \
-e MYSQL_ROOT_PASSWORD="root_pwd" \
--link mysql-server:mysql \
--link zabbix-server-mysql:zabbix-server \
-p 8080:8080 \
--restart unless-stopped \
-d zabbix/zabbix-web-nginx-mysql:latest

其他：以上是官方提供的docker镜像，本人制作了单一的zabbix镜像：
docker pull registry.cn-hangzhou.aliyuncs.com/luoxinli/zabbix
docker run 时只需要指定端口映射即可（80/10050/10051）
可docker exec进入容器修改配置文件

3、yum安装
(1)环境搭建

yum install -y httpd gcc gcc-c++ make #安装httpd
wget http://fping.org/dist/fping-3.4.tar.gz #安装fping
tar xf fping-3.4.tar.gz
cd fping-3.4
./configure
make && make install
#安装php
yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

(2)安装数据库（略，可参考本人关于cacti部署的文章）
(3)安装zabbix server

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm #安装yum源
yum -y install zabbix-server-mysql zabbix-web-mysql #安装zabbix-server
#配置mysql
mysql -uroot -ppassword
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'password';
mysql> quit;
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -pyourzabbixuserpwd zabbix
#修改zabbix及php配置文件
vim /etc/zabbix/zabbix_server.conf
>DBPassword=yourzabbixuserpwd
vim /etc/httpd/conf.d/zabbix.conf
>php_value date.timezone Asia/Shanghai
>php_value max_execution_time 300
>php_value memory_limit 128M
>php_value post_max_size 16M
>php_value upload_max_filesize 2M
>php_value max_input_time 300
>php_value max_input_vars 10000
>php_value always_populate_raw_post_data -1

(4)登录web界面按步骤进行安装

4、agent安装
(1)yum安装

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm #配置yum源
yum -y install zabbix-agent #安装agent
#修改配置文件
vim /etc/zabbix/zabbix_agentd.conf
>PidFile=/var/run/zabbix/zabbix_agentd.pid #按照所需配置pid文件路径
>LogFile=/var/log/zabbix/zabbix_agentd.log #按照所需配置日志文件路径
>EnableRemoteCommands=0 #去除此项的注释
>Server=192.168.11.151 #修改为zabbix server所在的服务器IP
>ListenPort=10050 #监听的端口，去掉注释，保持默认值
>ServerActive=192.168.11.151:10051 #修改为zabbix server所在的服务器IP

(2)编译安装（使用zabbix-server包）
①./configure --prefix=/usr/local/zabbix --agent-enable
②修改配置文件类似yum安装
(3)Windows安装
①官网下载相应安装包并解压到d:\zabbix
②使用管理员运行CMD
D:\zabbix\bin\zabbix_agentd.exe -i -c D:\zabbix\conf\zabbix_agentd.conf
D:\zabbix\bin\zabbix_agentd.exe -c D:\zabbix\conf\zabbix_agentd.conf -s

三、zabbix的使用
1、启用中文界面（需要先安装中文包：yum groupinstall “Chines Support”

2、创建主机

3、设置报警

PS：脚本名与在服务器中将创建的脚本名保持一致，参数将传至脚本，脚本中用$1,$2等提取参数

4、mysql监控
(1)授权mysql账号
grant all on *.* to zabbix@localhost identified by ‘zabbix’;
(2)建立zabbix的mysql连接信息文件/etc/zabbix/.my.cnf
[mysql]
host=localhost
user=zabbix
password=zabbix
socket=/var/lib/mysql/mysql.sock
[mysqladmin]
