修改以下参数为创建数据库时的信息,并重启zabbix-server
vim /etc/zabbix/zabbix_server.conf
DBName=zabbix
DBHost=192.168.179.132
DBUser=zabbix
DBPassword=zabbix
systemctl enable zabbix-server
systemctl start zabbix-server
启动的时候启动失败,查看系统日志,查找关键词
usr/sbin/zabbix_server: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
原来是缺少一个文件,yum安装解决yum -y install mysql-libs

测试是否能连接nginx,这里出现一个错误,访问动态页面一直显示文件没有发现,修改nginx配置文件的PHP脚本路径变量和修改文件权限后一直没有用,后来我将路径的变量去掉,添加网站真实路径后解决
yum install zabbix-agent
vim /etc/zabbix/zabbix-agentd.conf #Server和ServerActive分别代表zabbix的被动模式和主动模式,这里都填server端的IP
最后一行是开启脚本采集数据
cp -r /usr/share/zabbix/.* /usr/share/nginx/html/
egrep -v '(^.*#|^$)' /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name 192.168.179.132;
access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
error_page 404 /404.html;
location ~ \.php$ {

fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
重启nginx访问会报这个错
百度之后得知是权限不足引起的,运行一下命令可以解决,这里一定要777,不然到时候安装完成不能创建配置文件
chmod -R 777 /etc/zabbix/web
在访问浏览器的时候不出图,请教我学长之后得出是因为nginx上配置了图片缓存,去掉缓存解决
安装完成可能会遇到连接不上zabbix-server的错误,查看zabbix-server日志如下,这个解决方法有两种,第一种就是创建一个mysql.sock然后重启mysql服务器
mkdir /var/lib/mysql
ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
第二种就是编辑zabbix_server.conf文件,将DBSocket修改为自己数据库的mysql.sock,然后重启 zabbix_server
监控CPU idle
基本就是图形界面,创建监控项之前先测试一下key值是否可用,当然需要安装zabbix_get工具,使用yum install zabbix-get来安装
zabbix_get -s 192.168.179.132 -k system.cpu.util[all,idle,avg1]
监控磁盘IO利用的工具是iostat
yum install -y sysstat
编辑zabbix-agent的配置文件
vim /etc/zabbix/zabbix_agentd.d/userparameter.conf
UserParameter=disk.status[*],/usr/local/zabbix/scripts/disk-status.sh $1
vim /usr/local/zabbix/scripts/disk-status.sh
#!/bin/bash
if [ $# -ne 1 ];then
echo "Follow the script name with an argument"

touch +x /usr/local/zabbix/scripts/disk-status.sh #给脚本添加执行权限
浏览器打开192.168.179.132/index.php
依次点击配置——>模板——>创建模板
添加模板名称以及群组,最后点击添加
在创建的模板上点击创建应用集,名字最好与磁盘io相关
这里所有的数据类型都是浮点数
这需要为每一个监控项都创建图形
点击需要监控的主机,然后单击模板,为主机添加模板链接
可以看到我收集到的图形是乱码的
首先查看zabbix字体目录,它定义的路径是“fonts”,它是一个相对路径,绝对路径为/usr/share/zabbix/fonts,
vim /usr/share/zabbix/include/defines.inc.php //搜索ZBX_FONTPATH
而字体文件为“ZBX_GRAPH_FONT_NAME”所定义的“graphfont”,它是一个文件,绝对路径为/usr/share/zabbix/fonts/graphfont.ttf
我们可以从Windows系统中选择一个中文字体然后放到zabbix的字体目录下
Windows字体目录位于C:\Windows\Fonts下,找到仿宋常规字体将他拷入zabbix字体目录下
然后修改PHP文件,将字体文件修改为simsong
yum install java #elastic需要安装Java依赖
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.4.tar.gz
tar -xvf elasticsearch-6.1.4.tar.gz
vim /root/elasticsearch-6.1.4/config/elasticsearch.yml #主要修改es的一些配置信息
启动过程出现的报错
[WARN ][o.e.b.BootstrapChecks ] [PWm-Blt] max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
解决办法:
vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
[WARN ][o.e.b.BootstrapChecks ] [PWm-Blt] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决办法:
vim /etc/sysctl.confvm.max_map_count=655360
修改完成执行命令:
sysctl -p
cd elasticsearch-6.1.4/bin
这里不能使用root用户运行elastic,可以自己新建一个普通用户,还要把目录授予普通用户权限
./elasticsearch
然后我们可以打开浏览器输入192.168.179.133:9200可以查看es的状态,或者可以装一个head插件
这里我采用的源码安装,其实二进制安装是比较简单的,但我执行到最后node的二进制文件无法执行,因此只能源码安装,时间有点长,打了两局王者荣耀才装完
yum groupinstall "Development Tools" #安装编译必要的工具
wget https://nodejs.org/dist/v8.11.4/node-v8.11.4.tar.gz #下载node的源码包
tar -zxvf node-v8.11.4.tar.gz #解压源码包
cd node-v8.11.4
./configure && make && make install #执行编译安装
echo $? #查看执行结果,输出0表示安装成功
node.js默认安装路径在/usr/local/bin/目录下
grunt是基于Node.js的项目构建工具,可以进行打包压缩、测试、执行等等的工作,head插件就是通过grunt启动npm install -g grunt-cli
git clone git://github.com/mobz/elasticsearch-head.git #克隆head插件仓库
cd elasticsearch-head/
npm install #执行完会报一些错误,不要管执行下一条命令就会解决
npm install [email protected] --ignore-scripts
vim /elasticsearch/elasticsearch-6.4.0/config/elasticsearch.yml
http.cors.enabled: true # elasticsearch中启用CORS
http.cors.allow-origin: "*" # 允许访问的IP地址段,* 为所有IP都可以访问
npm run start #启动head插件
在浏览器输入http://192.168.179.133:9100/ 即可使用head插件
添加如下内容
HistoryStorageURL=192.168.179.133:9200
HistoryStorageTypes=str,text,log,uint,dbl
HistoryStorageDateIndex=1
添加如下内容
global $DB, $HISTORY;
$HISTORY['url'] = 'http://192.168.179.133:9200';
// Value types stored in Elasticsearch.
$HISTORY['types'] = ['str', 'text', 'log','uint','dbl'];
systemctl restart zabbix-server
至此,es收集zabbix历史数据完成
