zabbix安装使用

1.常见错误

• yum 源报错

  # 修改文件 /etc/yum.repos.d/CentOS-SCLo-scl.repo
  vim /etc/yum.repos.d/CentOS-SCLo-scl.repo
  
  # 替换

   # 引入GPGKEY
  rpm --import https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
  rpm --import https://www.centos.org/keys/RPM-GPG-KEY-CentOS-SIG-SCLo
  
  yum clean all
  yum makecache
  yum -y update

• 关闭selinux模式（安全策略）

  # 修改配置文件 enforcing开启 disabled关闭
  vim /etc/selinux/config
  # This file controls the state of SELinux on the system.
  # SELINUX= can take one of these three options:
  #     enforcing - SELinux security policy is enforced.
  #     permissive - SELinux prints warnings instead of enforcing.
  #     disabled - No SELinux policy is loaded.
  SELINUX=disabled
  
  # getenforce 查看当前状态
  getenforce

2.安装配置（服务端，基于nginx+mysql)

2.1安装仓库

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# 换源
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
yum clean all
yum makecache

2.2安装Zabbix server，Web前端，agent

yum install zabbix-server-mysql zabbix-agent -y

2.3安装Zabbix前端

yum install centos-release-scl -y

2.3.1编辑配置文件 /etc/yum.repos.d/zabbix.repo

[zabbix-frontend]
...
enabled=1
...

2.3.2安装 Zabbix frontend packages.

yum install zabbix-web-mysql-scl zabbix-nginx-conf-scl -y

2.4创建初始数据库

# 安装数据库
yum install -y mariadb-server

# mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;

2.4.1导入初始架构和数据，系统将提示您输入新创建的密码。

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

2.4.2Disable log_bin_trust_function_creators option after importing database schema.

# mysql -uroot -p
password
mysql> set global log_bin_trust_function_creators = 0;
mysql> quit;

2.5为Zabbix server配置数据库

编辑配置文件 /etc/zabbix/zabbix_server.conf

vim /etc/zabbix/zabbix_server.conf
DBPassword=password

2.6为Zabbix前端配置PHP

编辑配置文件 /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf uncomment and set 'listen' and 'server_name' directives.

listen 80;
server_name localhost;

编辑文件/etc/opt/rh/rh-nginx116/nginx/nginx.conf

# 注释server块
# server{
#		...
#		listen 80;
#		...
# }

编辑配置文件 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf add nginx to listen.acl_users directive.

listen.acl_users = apache,nginx

php_value[date.timezone] = Asia/Shanghai

2.7启动Zabbix server和agent进程

systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm

2.8安装字体解决图表文字有乱码的问题

# 服务端安装字体
yum install -y wqy-microhei-fonts
# 拷贝字体到特定的位置
cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf

3.安装配置（客户端)

• 旧版本客户端，zabbix-agent
• go语言新版，zabbix-agent2

3.1确保客户端机器时间正确

# 统一时间
yum install -y ntpdate
ntpdate -u ntp.aliyun.com

# 统一时区
mv /etc/localtime{,.bak}
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

3.2安装客户端

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# 换源
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
yum clean all
yum makecache

yum install zabbix-agent2 -y

查看配置文件

vim /etc/zabbix/zabbix_agent2.conf

cp /etc/zabbix/zabbix_agent2.conf{,.bak}

sed -i "s/^Server=127.0.0.1$/Server=172.172.1.1/" /etc/zabbix/zabbix_agent2.conf && sed -i "s/^ServerActive=127.0.0.1$/ServerActive=172.172.1.1/" /etc/zabbix/zabbix_agent2.conf && sed -i "s/^Hostname=Zabbix server$/Hostname=`hostname`/" /etc/zabbix/zabbix_agent2.conf
# 修改服务端地址
Server=服务端地址(如果是docker部署使用docker网关)
ServerActive=服务端地址(如果是docker部署使用docker网关)

# 修改客户端主机名
Hostname=客户端主机名

启动命令

ls -l /usr/sbin/zabbix_agent2

启动客户端

# 默认端口10050
systemctl enable --now zabbix-agent2

验证zabbix-agent2的连通性

# 在服务端安装 zabbix-get工具
yum install -y zabbix-get

# 测试 返回1则连接成功
zabbix_get -s '客户端ip' -p 10050 -k 'agent.ping'
# 获取主机名
zabbix_get -s '客户端ip' -p 10050 -k 'system.hostname'

4.完全卸载zabbix

• 停止服务

  # nginx
  systemctl stop zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
  # apache
  systemctl stop zabbix-server zabbix-agent rh-php72-php-fpm httpd

• 删除zabbix相关包

  yum -y remove `rpm -qa | grep -i zabbix`

• 删除相关文件

  rm -rf `find / -name zabbix`

• 卸载数据库

  yum -y remove `rpm -qa | grep mariadb`

• 删除数据库相关文件

  rm -rf `find / -name mysql`

• 卸载http服务

  yum -y remove `rpm -qa|grep httpd`

• 卸载php服务

  yum -y remove `rpm -qa|grep rh-php72-php-fpm`

• 卸载nginx服务

  yum -y remove `rpm -qa|grep nginx`
