一、监控的选型
- 以前用的监控：Nagios+Cacti
- 现在使用监控： Zabbix+Grafana，OpenFalcon，Prometheus
二、Zabbix监控架构
1. Zabbix生命周期
- LTS：Long time support 长期维护版本
2. Zabbix的监控架构
- Zabbix是一个CS（服务端/客户端）架构的服务
- Zabbix-agent(客户端)获取数据—>发送给Zabbix-server(服务端)
- 数据会被存放在数据库内
- Zabbix Web从数据库内取出数据并展示出来
三、Zabbix极速上手指南
- 系统： centos 7.x，不支持yum方式安装服务端。
- 安装方式：服务端编译安装
- zabbix官网：Download Zabbix sources
Zabbix 服务端编译安装流程
1. 安装 ngx+php环境
2. 安装mysql 5.7 或者 mariadb 10.5
3. 编译安装Zabbix服务端及配置
4. 部署前端页面
1. 部署ngx+php环境
- 部署Nginx
# 1. 配置Nginx yum源
cat /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=https://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
# 安装 nginx
yum -y install nginx --enablerepo=nginx-stable
- 部署php
yum -y install epel-release.noarch
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum -y install php72w-cli php72w-fpm php72w-gd php72w-mbstring php72w-bcmath php72w-xml php72w-ldap php72w-mysqlnd
- nginx配置
root@master:/etc/nginx/conf.d # cat zbx.yzs.cn.conf
server{
listen 80;
server_name zbx.yzs.cn;
root /app/code/zbx/;
location / {
index index.php;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /app/code/zbx$fastcgi_script_name;
include fastcgi_params;
}
}
- php配置
# 1.替换
root@master:/etc/nginx/conf.d # sed -ri '/^(user|group)/s#apache#nginx#g' /etc/php-fpm.d/www.conf
# 2. 检查
root@master:/etc/nginx/conf.d # egrep '^(user|group)' /etc/php-fpm.d/www.conf
user = nginx
group = nginx
- 创建目录和文件，启动服务并测试
# 1.创建目录和测试文件
root@master:/etc/nginx/conf.d # mkdir -p /app/code/zbx
root@master:/etc/nginx/conf.d # vim /app/code/zbx/info.php
root@master:/etc/nginx/conf.d # cat /app/code/zbx/info.php
phpinfo();
?>
# 2. 启动服务和设置开机自启动
root@master:/etc/nginx/conf.d # systemctl start nginx php-fpm.service
root@master:/etc/nginx/conf.d # systemctl enable nginx php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
- web测试（域名访问需要本地hosts解析）
2. 部署数据库
- Zabbix 6.0 不支持 mariadb 5.5 （默认源中的）
- 个人选择mysql，安装mysql
# 1. 下载mysql源
wget https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm
# 2. 安装mysql的yum仓库
yum -y localinstall mysql80-community-release-el7-7.noarch.rpm
# 3.修改yum仓库，默认安装8.0版本，不安装5.7
yum-config-manager --disable mysql57-community
yum-config-manager --enable mysql80-community
# 4.安装数据库
yum install -y mysql-community-server
# 5.启动数据库和开机自启动
root@master:/etc/yum.repos.d # systemctl start mysqld && systemctl enable mysqld
root@master:/etc/yum.repos.d # ss -ntulp | grep 3306
tcp LISTEN 0 80 [::]:3306 [::]:* users:(("mysqld",pid=29908,fd=21))
# 6. 查找密码
root@master:/etc/yum.repos.d # grep pass /var/log/mysqld.log
2024-04-04T06:11:26.701823Z 1 [Note] A temporary password is generated for root@localhost: L=FqNR%sz5hz
# 7. 修改密码
root@master:/etc/yum.repos.d # mysqladmin -u root -p'L=FqNR%sz5hz' password 'Yangzs@123'
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
# 8. 测试登录
root@master:/etc/yum.repos.d # mysql -u root -p'Yangzs@123'
mysql: [Warning] Using a password on the command line interface can be insecure.

- 创建Zabbix库和用户
# Zabbix 创建数据库要指定字符集
# 1. 创建库
mysql> create database zabbix charset utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)
# 2.创建用户
mysql> grant all on zabbix.* to 'zabbix'@localhost' identified by 'yzeSen@1';
Query OK, 0 rows affected, 1 warning (0.00 sec)
3. 下载Zabbix源码包，导入数据
- 下载源码包，并解压
root@master:/root # wget --no-check-certificate https://cdn.zabbix.com/zabbix/sources/stable/6.0/zabbix-6.0.28.tar.gz
root@master:/root # tar xf zabbix-6.0.28.tar.gz
- 导入数据
# 1. 进入存放sql的目录
root@master:/root # cd zabbix-6.0.28/database/mysql
# 2. 按照顺序导入sql
mysql -u root -p'Yangzs@123' zabbix < schema.sql
mysql -u root -p'Yangzs@123' zabbix < images.sql
mysql -u root -p'Yangzs@123' zabbix < data.sql
mysql -u root -p'Yangzs@123' zabbix < double.sql
mysql -u root -p'Yangzs@123' zabbix < history_pk_prepare.sql
4. 编译安装Zabbix服务端及配置
- 准备编译zabbix-server
# 1. 进入源码目录
root@master:/root # cd zabbix-6.0.28/database/mysql
# 2. 安装依赖
yum -y install mysql-devel pcre-devel openssl-devel zlib-devel libxml2-devel net-snmp-devel net-snmp libssh2-devel OpenIPMI-devel libevent-devel openldap-devel libcurl-devel
# 3.编译安装，参考下图1：https://tiknmp6phqg.feishu.cn/docx/A8Ssd0z2Vok1i5xsFJjc93IGnyh#PnaodfweYoMBFNxufxycJKLznzd
root@master:/root/zabbix-6.0.28 # ./configure \
> --sysconfdir=/etc/zabbix/ \
> --enable-server \
> --with-mysql \
> --with-net-snmp \
> --with-libxml2 \
> --with-ssh2 \
> --with-openipmi \
> --with-zlib \
> --with-libpthread \
> --with-libevent \
> --with-openssl \
> --with-ldap \
> --with-libcurl \
> --with-libpcre
# 4. 编译成功后，提示我们直接 make install,如图2
root@master:/root/zabbix-6.0.28 # make install
# 5.检查是否成功，待make install执行结束后，执行下面语句，为0则成功
root@master:/root/zabbix-6.0.28 # echo $?
0
# 6. 查看zabbix版本
root@master:/root/zabbix-6.0.28 # zabbix_server --version
zabbix_server (Zabbix) 6.0.28
