ubuntu16.04 安装zabbix-server和zabbix-agent

 

 

 一、必要条件

0、必要条件

zabbix-server已经安装lnmp或者lamp环境

安装nginx

1 sudo apt-get install nginx

安装mysql

1 sudo apt-get install mysql-server mysql-client

 

安装php

1 sudo apt-get install php-fpm php-gd php-mbstring php-curl php-xml php-mcrypt php-mysql php-zip php-json php-redis php-memcached

 

 

配置php.ini

max_execution_time = 600
max_input_time = 600
memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 16M
date.timezone = Asia/Shanghai

 

 

1 ps -ef | grep nginx #查看nginx进程
2 /usr/sbin/nginx -t  #确认nginx的配置文件位置

root@HOSTNAME:~# /usr/sbin/nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

/etc/nginx/nginx.conf的部分内容如下：

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;

#从配置文件/etc/nginx/nginx.conf，可以确认，目前默认使用的是/etc/nginx/sites-enabled/default

#编辑/etc/nginx/sites-enabled/default文件，打开php-fpm，这里使用的是php-fpm
{......}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #       # With php7.0-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
                # With php7.0-fpm:
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

{......}

 

二、服务端安装（zabbix-server） 

1、安装zabbix-server

1 sudo wget http://repo.zabbix.com/zabbix/4.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.2-1%2Bxenial_all.deb
2 sudo dpkg -i zabbix-release_4.2-1+xenial_all.deb
3 sudo apt-get update
4 sudo apt-get install zabbix-server-mysql zabbix-frontend-php

2、初始化zabbix数据库

1 mysql -u root -p

#以下命令是在mysql中运行
1 create database zabbixdb character set utf8;
2 grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by 'password';
3 flush privileges;

导入数据

1 cd /usr/share/doc/zabbix-server-mysql/
2 zcat create.sql.gz | mysql -uroot -p zabbixdb  #此处输入mysql的root密码

配置zabbix-server

1 vim /etc/zabbix/zabbix_server.conf

修改以下关键位置

[...]
DBHost=localhost
[...]
DBName=zabbixdb
[...]
DBUser=zabbixuser
[...]
DBPassword=password
[...]

 

 

注意：如果开启了ufw，需要添加以下配置

firewall-cmd --permanent --add-port=10050/tcp
firewall-cmd --permanent --add-port=10051/tcp
systemctl restart firewalld

如果开启了selinux（Linux系统，比如Centos、Redhat等），添加以下配置

setsebool -P httpd_can_connect_zabbix=1
semanage permissive -a zabbix_agent_t

 

3、配置zabbix-server的前端

将zabbix文件移动（或者拷贝）到网站目录下

1 mv /usr/share/zabbix /var/www/html

访问 http://ip-address/zabbix或者 http://domain-name/zabbix

所有选项都是ok才可以下一步

 

 

注意：这里配置的是mysql设置的信息

完成之后，默认的登陆方式为

admin/zabbix

 

三、优化操作

1、zabbix-agent自动注册到zabbix-server

• Configuration--Actions--Create action

可使用host name、host metadata或者proxy方式

 

 

 

 前端配置完成之后，需要在agent进行配置

 

四、客户端安装

1、zabbix-agent安装

1 sudo wget http://repo.zabbix.com/zabbix/4.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.2-1%2Bxenial_all.deb
2 sudo dpkg -i zabbix-release_4.2-1+xenial_all.deb
3 sudo apt-get update
4 sudo apt-get install zabbix-agent

 

2、修改配置文件

2.1、修改脚本

建议使用脚本批量修改

注1：192.168.100.133是zabbix-server地址

注2：如果自动注册使用Host metadata方式，需要将# HostMetadataItem=修改为HostMetadata=(前端配置的名字，自定义)

注3：如果自动注册使用Host name方式，需要将# HostMetadataItem=修改为HostMetadataItem=system.uname(值来自key)

zabbix_agent_conf_replace.sh

 

#! /usr/bin/env bash
ZABBIX_HOSTNAME=$(hostname)
sed -i "s/^Hostname=Zabbix server/Hostname=$ZABBIX_HOSTNAME/g" /etc/zabbix/zabbix_agentd.conf
sed -i "s/^ServerActive=127.0.0.1/ServerActive=192.168.100.133/g" /etc/zabbix/zabbix_agentd.conf
sed -i "s/^Server=127.0.0.1/Server=192.168.100.133/g" /etc/zabbix/zabbix_agentd.conf
sed -i "s/^# UnsafeUserParameters=0/UnsafeUserParameters=1/g" /etc/zabbix/zabbix_agentd.conf
sed -i "s/^# HostMetadataItem=/HostMetadata=（前端配置的名字）/g" /etc/zabbix/zabbix_agentd.conf 
systemctl restart zabbix-agent.service 
systemctl enable zabbix-agent.service

 

 

 

 2.2、上传脚本至服务器

在自己笔记本或者中控服务器上（需要跟各服务器能通）定义列表environment.list

# 集群各机器 IP 数组
export NODE_IPS=(192.168.100.111 192.168.100.112 192.168.100.114 192.168.100.119 192.168.100.119 192.168.100.124 192.168.100.115 192.168.100.113 192.168.100.120 192.168.100.126 192.168.100.127)

1 source environment.list
2 for node_ip in ${NODE_IPS[@]};   do     echo ">>> ${node_ip}";     scp ./zabbix_replace.sh ${node_ip}:/tmp;   done
3 pssh -i -h server.list "sudo su - root -c 'sh /tmp/zabbix_replace.sh'"

正常情况下，到这里就完成了部署和自动注册上线

 

 

 

五、遇到的问题

1、php无法解析

原因：未开启php-fpm（或者php-cgi）

解决：nginx配置文件（/etc/nginx/sites-enabled/default）里，server选项里开启php-fpm即可

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        # SSL configuration
        #
        # listen 443 ssl default_server;
        # listen [::]:443 ssl default_server;
        #
        # Note: You should disable gzip for SSL traffic.
        # See: https://bugs.debian.org/773332
        #
        # Read up on ssl_ciphers to ensure a secure configuration.
        # See: https://bugs.debian.org/765782
        #
        # Self signed certs generated by the ssl-cert package
        # Don't use them in a production server!
        #
        # include snippets/snakeoil.conf;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html index.php;

        server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #       # With php7.0-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
                # With php7.0-fpm:
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #       deny all;
        #}
}

 

2、nginx 403

（directory index of "/var/www/html/zabbix/" is forbidden）

原因：nginx里未配置php的允许

解决：nginx配置文件（/etc/nginx/sites-enabled/default）里，server选项里添加index.php即可

 

3、附件：默认配置文件

/etc/nginx/nginx.conf
