Zabbix部署
文章目录
一、LNMP安装环境
1、安装nginx1.14
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
#需要搭配本地源，千万不要移动到别的地方
vim /etc/yum.repos.d/nginx.repo
#手动创建nginx yum安装源
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
其中baseurl=http/nginx.org/packages/OS/OSRELEASE/$basearch/，把"” OS”替换成” rhel”或" centos”，把” OSRELEASE”替换成”6”或”7”
yum clean all
yum list
yum install nginx -y #安装nginx，默认为nginx-1.12.2
systemctl start nginx
systemctl enable nginx
#检查防火墙是否关闭
试访问192.168.171.7
2、安装mysql 5.7
yum install -y mariadb-server mariadb
systemctl enable mariadb.service
systemctl start mariadb.service
mysql_secure_installation #会进入设置阶段
具体操作
Enter current password for root (enter for none): #回车
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y #属入y
New password: #设置密码
Re-enter new password: #再次密码
Password updated successfully!
Reloading privilege tables..
... Success!
Remove anonymous users? [Y/n] n #n不删除匿名用户
... skipping.
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n #n允许远程登录
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] n #n不删除测试数
... skipping.
Reload privilege tables now? [Y/n] y #y重新加载刷新
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
验证密码是否设置成功
mysql -uroot -p
3、安装php 7.2
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
或
yum install epel-release -y （没成功）
#yum仓库建立
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
#yum源等待时间取决于网络
yum install -y php72w php72w-devel php72w-fpm php72w-gd php72w-mbstring php72w-mysql
php -v
#查看php版本
4、配置nginx支持php
vim /etc/php-fpm.d/www.conf
#修改php-fpm配置文件。把apache改为nginx
//8 user = nginx
//10 group = nginx
vim /etc/nginx/conf.d/default.conf
#配置location，在index中添加index.php。以支持index.php的首页
#第10行 index index.php index.html index.htm;
#第30~36行
#配置php请求被传送到后端的php-fpm模块
#默认情况下php配置块是被注释的，去掉注释并修改
#把fastcgi_param中的/scripts改为$document_root。root是配置php程序放置的根目录。
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_scri pt_name;
include fastcgi_params;
}
5、配置PHP
vim /etc/php.ini
#359行 expose_php = Off //隐藏php版本
#202行 short_open_tag = On //支持php短标签
---以下为zabbix配置要求---
#368行 max_execution_time = 300 //执行时间
#378行 max_input_time = 300 //接收数据等待时间
#389行 memory_limit = 128M //每个脚本占用内存
#656行 post_max_size = 16M //POST数据大小
#799行 upload_max_filesize = 2M //下载文件大小
#800行添加 always_populate_raw_post_data = -1 //可以用 $HTTP_RAW_POST_DATA 接收post raw data
#877行 date.timezone = Asia/Shanghai //时区
systemctl start php-fpm.service
systemctl enable php-fpm.service
systemctl restart nginx
6、测试首页
vim /usr/share/nginx/html/info.php
<?php
phpinfo();
?>
访问192.168.171.7/info.php

7、测试连接数据库
vim /usr/share/nginx/html/info.php
<?php
$link=mysqli_connect('127.0.0.1','root','abc123');
if ($link) echo "连接成功!!!";
else echo "连接失败!!!";
?>
注：mysql_connect扩展自 PHP 5.5.0 起已废弃，改用mysqli或pdo_mysql
http://192.168.171.7/info.php
8、准备安装Zabbix操作
mysql -uroot -pabc123
CREATE DATABASE zabbix character set utf8 collate utf8_bin;
GRANT all privileges ON *.* TO 'zabbix'@'%' IDENTIFIED BY 'admin123';
flush privileges;
#collate的作用
对于mysql中那些字符类型的列，如VARCHAR,CHAR,TEXT类型的列，都需要有一个COLLATE类型来告知mysql如何对该列进行排序和比较。
show databases;
vim /usr/share/nginx/html/info.php
<?php
$link=mysqli_connect('127.0.0.1','zabbix','admin123');
if ($link) echo "Zabbix数据库连接成功!";
else echo "Zabbix数据库连接失败!";
?>
解决以上连接失败的办法
mysql -uroot -pabc123
select user,host from mysql.user;
drop user ''@localhost;
drop user ''@localhost.localdomain;
select user,host from mysql.user;
二、部署Zabbix Server
zabbix 官网 https://www.zabbix.com/download
1、安装yum源
rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
#警告：/var/tmp/rpm-tmp.ReqDjI: 头V4 RSA/SHA512 Signature, 密钥 ID a14fe591: NOKEY
2、安装所需环境包
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y
3、更改配置文件
vim /etc/zabbix/zabbix_server.conf
38:LogFile=/var/log/zabbix/zabbix_server.log
49:LogFileSize=0
72:PidFile=/var/run/zabbix/zabbix_server.pid
82:SocketDir=/var/run/zabbix
91:DBHost=localhost //注释去掉
100:DBName=zabbix
116:DBUser=zabbix
124:DBPassword=admin123 //设置zabbix密码
356:SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
473:Timeout=4
516:AlertScriptsPath=/usr/lib/zabbix/alertscripts
527:ExternalScripts=/usr/lib/zabbix/externalscripts
563:LogSlowQueries=3000
#检查配置文件
grep -n '^'[a-Z] /etc/zabbix/zabbix_server.conf
4、详细优化（可不选）
修正图表中文乱码（可不配）
vim /usr/share/zabbix/include/defines.inc.php
:%s /graphfont/kaiti/g
#同时按住shift与：键
从微软系统下复制相应的字体文件到 /usr/share/zabbix/fonts 目录中注意字体名称要对应配置文件，且注意大小写（可不配）
cp STKAITI.TTF /usr/share/zabbix/fonts/
5、赋予权限
setenforce 0
#一定要关闭！
cp -r /usr/share/zabbix/ /usr/share/nginx/html/
chown -R zabbix:zabbix /etc/zabbix
chown -R zabbix:zabbix /usr/share/nginx/
chown -R zabbix:zabbix /usr/lib/zabbix/
#处理指定目录以及其子目录下的所有文件
chmod -R 755 /etc/zabbix/web/
chmod -R 777 /var/lib/php/session/
#归修改文件权限
6、生成数据库文件并查看
密码是数据库的密码
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
mysql -uzabbix -p
use zabbix;
show tables;
quit
修改时区
vim /etc/httpd/conf.d/zabbix.conf
#20行 php_value date.timezone Asia/Shanghai
systemctl start zabbix-server.service
systemctl enable zabbix-server.service
systemctl start zabbix-agent.service
systemctl enable zabbix-agent.service
netstat -anpl | grep 10051
systemctl restart php-fpm.service
systemctl restart nginx
7、安装登录验证
http://192.168.171.7/zabbix/
**用户名：Admin **
密码：zabbix
授权并重启服务
chown zabbix.zabbix /etc/zabbix/web/zabbix.conf.php
systemctl restart zabbix-server.service
最后登录
三、部署Zabbix agent
网络配置环境
#清空防火墙规则，关闭核心防护
iptables -F
setenforce 0
#关闭网络管理
systemctl stop NetworkManager
systemctl disable NetworkManager
安装配置Zabbix
rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
yum install -y zabbix-agent
修改配置文件
vim /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
...
Server=192.168.171.7 #指向监控服务器 98行
ServerActive=192.168.171.7 #指问监控服务器 139行
Hostname=test1 #指定名称 150行
Include=/etc/zabbix/zabbix_agentd.d/*.conf
---下一步---
systemctl start zabbix-agent.service && systemctl enable zabbix-agent.service
netstat -ntap |grep 'zabbix'
四、Zabbix监控
创建主机
- 现在可以监听httpd sshd 服务
- 有问题会显示到web界面
查看监控数据
可以点击右下角“图形”切换视图
