LNMP+发布Zabbix监控

一、本次实验使用环境

1、192.168.1.105 Zabbix Server

Linux+Nginx+PHP+MariaDB+Zabbix Server

2、192.168.1.106 Zabbix Agent

Linux+Zabbix Agent

二、安装 LNMP 架构环境

1、先关闭CentOS系统防火墙

[root@localhost ~]# systemctl stop firewalld

2、安装 Nginx
①、安装PCRE库和基础库支持

[root@localhost ~]# yum install pcre-devel pcre gcc-c++ openssl openssl-devel zlib-devel -y

②、下载 Nginx 源码包

[root@localhost ~]# yum install wget -y
[root@localhost ~]# wget -c https://www.kuaidown.top/Linux/nginx-1.14.2.tar.gz

③、解压 Nginx 源码包，并创建服务用户

[root@localhost ~]# tar -xzf nginx-1.14.2.tar.gz
[root@localhost ~]# useradd -s /sbin/nologin nginx -M

④、进入 Nginx 源码包，进行预编译、编译与编译安装

[root@localhost ~]# cd nginx-1.14.2
[root@localhost nginx-1.14.2]# ./configure --prefix=/data/nginx --with-http_stub_status_module --with-http_ssl_module
[root@localhost nginx-1.14.2]# make && make install

⑤、检查 Nginx 配置文件是否正确，并启动服务

[root@localhost nginx-1.14.2]# /data/nginx/sbin/nginx -t
nginx: the configuration file /data/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /data/nginx/conf/nginx.conf test is successful
[root@localhost nginx-1.14.2]# /data/nginx/sbin/nginx-

⑥、修改 Nginx 配置文件

[root@localhost nginx-1.14.2]# yum install vim -y
[root@localhost nginx-1.14.2]# vim /data/nginx/conf/nginx.conf

    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

3、安装 PHP 源码包
①、安装编译需要的依赖

[root@localhost ~]# yum install gd curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql-devel -y

②、下载 PHP 源码包

[root@localhost ~]# wget -c https://www.kuaidown.top/Linux/php-5.6.9.tar.gz

③、解压 PHP 源码包，并进行预编译、编译与编译安装

[root@localhost ~]# tar -xzf php-5.6.9.tar.gz
[root@localhost ~]# cd php-5.6.9
[root@localhost php-5.6.9]# ./configure --prefix=/data/php5 --enable-fpm --enable-debug --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-curl --with-mysql --with-mysqli --disable-fileinfo --enable-bcmath --enable-sockets
[root@localhost php-5.6.9]# make && make install

④、编辑 PHP 文件权限与配置文件

[root@localhost php-5.6.9]# \cp php.ini-development /data/php5/lib/php.ini
[root@localhost php-5.6.9]# \cp /data/php5/etc/php-fpm.conf.default /data/php5/etc/php-fpm.conf
[root@localhost php-5.6.9]# \cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.6.9]# chmod 755 /etc/init.d/php-fpm
[root@localhost php-5.6.9]# chkconfig --add php-fpm
[root@localhost php-5.6.9]# chkconfig php-fpm on

⑤、修改 PHP 配置文件

[root@localhost php-5.6.9]# vim /data/php5/etc/php-fpm.conf

25 ;pid = run/php-fpm.pid   #原来
25 pid = run/php-fpm.pid   #修改为

149 user = nobody   #原来
149 group = nginx   #修改为

150 group = nobody   #原来
150 user = nginx   #修改为

4、YUM方式安装 MariaDB，并启动

[root@localhost ~]# yum install mariadb mariadb-devel mariadb-server -y
[root@localhost ~]# systemctl start mariadb

三、安装Zabbix Server端

1、下载 Zabbix 软件源码包

[root@localhost ~]# wget -c https://www.kuaidown.top/Linux/zabbix-4.2.5.tar.gz

2、安装编译所需组件，并创建服务用户

[root@localhost ~]# yum install curl curl-devel net-snmp libevent-devel net-snmp-devel perl-DBI mariadb-devel mysql-devel -y
[root@localhost ~]# groupadd  zabbix
[root@localhost ~]# useradd -g zabbix zabbix
[root@localhost ~]# usermod -s /sbin/nologin zabbix

3、创建 Zabbix 数据库连接用户

MariaDB [(none)]> create database zabbix charset=utf8;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all on zabbix.* to zabbix@'192.168.1.105' identified by "gdl";
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

4、解压 Zabbix 软件包并将 Zabbix 基础SQL文件导入数据至 Zabbix 数据库

[root@localhost ~]# tar -xzf zabbix-4.2.5.tar.gz
[root@localhost ~]# cd zabbix-4.2.5
[root@localhost zabbix-4.2.5]# mysql -uzabbix -pgdl zabbix 
[root@localhost zabbix-4.2.5]# mysql -uzabbix -pgdl zabbix 
[root@localhost zabbix-4.2.5]# mysql -uzabbix -pgdl zabbix < database/mysql/data.sql

5、预编译、编译与编译安装 Zabbix_server

[root@localhost zabbix-4.2.5]# ./configure --prefix=/usr/local/zabbix/ --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl
[root@localhost zabbix-4.2.5]# make && make install
[root@localhost zabbix-4.2.5]# ln -s /usr/local/zabbix/sbin/zabbix_* /usr/local/sbin/

6、进入 Zabbix 备份配置文件

[root@localhost zabbix-4.2.5]# cd /usr/local/zabbix/etc
[root@localhost etc]# cp zabbix_server.conf zabbix_server.conf.bak

7、修改 Zabbix 配置文件

LogFile=/tmp/zabbix_server.log
DBHost=localhost   #需要取消注释
DBName=zabbix
DBUser=zabbix
DBPassword=gdl   #需要取消注释

8、拷贝 zabbix_server 启动脚本至 /etc/init.d/ 目录

[root@localhost ~]# cd /root/zabbix-4.2.5
[root@localhost zabbix-4.2.5]# cp misc/init.d/tru64/zabbix_server /etc/init.d/zabbix_server
[root@localhost zabbix-4.2.5]# chmod o+x /etc/init.d/zabbix_server

9、拷贝 Zabbix WEB 文件进 Nginx 发布目录

[root@localhost zabbix-4.2.5]# cp -a frontends/php/* /data/nginx/html/

10、重新启动Nginx、PHP服务

[root@localhost zabbix-4.2.5]# /data/nginx/sbin/nginx -s reload
[root@localhost zabbix-4.2.5]# systemctl restart php-fpm

11、访问网页进行安装 Zabbix
①、访问192.168.1.105/index.php


②、出现配置出错，进行修改

[root@localhost ~]# cd /data/php5/lib
[root@localhost lib]# vim php.ini

660 post_max_size = 16M
372 max_execution_time = 300
382 max_input_time = 300
927 date.timezone = Asia/shanghai
704 always_populate_raw_post_data = -1

③、重启 Nginx、PHP

[root@localhost lib]# systemctl restart php-fpm
[root@localhost lib]# /data/nginx/sbin/nginx -s reload

④、刷新页面继续进行安装





⑤、下载文件放入 /data/nginx/html/conf

将文件下载本机后，在上传服务器
[root@localhost conf]# yum install lrzsz -y
然后就可以上传服务器了
刷新页面

⑥、账号与密码

默认账号：admin
默认密码：zabbix

⑦、启动 Zabbix Server

[root@localhost conf]# cd /usr/local/zabbix/sbin/
[root@localhost sbin]# ./zabbix_server

到这里 Zabbix Server端就配置完成了

四、安装Zabbix Agent端

1、安装编译所需组件，并创建服务用户

[root@localhost ~]# yum install gcc-c++ curl curl-devel net-snmp libevent-devel net-snmp-devel perl-DBI mariadb-devel mysql-devel -y
[root@localhost ~]# groupadd  zabbix
[root@localhost ~]# useradd -g zabbix zabbix
[root@localhost ~]# usermod -s /sbin/nologin zabbix

2、下载 Zabbix 软件源码包

[root@localhost ~]# wget -c https://www.kuaidown.top/Linux/zabbix-4.2.5.tar.gz

3、解压 Zabbix 源码包，进行预编译、编译与编译安装 Zabbix

[root@localhost ~]# tar -xzf zabbix-4.2.5.tar.gz
[root@localhost ~]# cd zabbix-4.2.5
[root@localhost zabbix-4.2.5]# ./configure --prefix=/usr/local/zabbix --enable-agent
[root@localhost zabbix-4.2.5]# make && make install

4、修改 Zabbix 客户端配置文件

[root@localhost zabbix-4.2.5]# cd /usr/local/zabbix/etc
[root@localhost etc]# cp zabbix_agentd.conf zabbix_agentd.conf.bak
[root@localhost etc]# vim zabbix_agentd.conf

94 Server=192.168.1.105
135 ServerActive=192.168.1.105
146 Hostname=192.168.1.106

5、拷贝 zabbix_agentd启动脚本至 /etc/init.d/ 目录，并启动

[root@localhost etc]# cd /root/zabbix-4.2.5
[root@localhost zabbix-4.2.5]# cp misc/init.d/tru64/zabbix_agentd /etc/init.d/zabbix_agentd
[root@localhost ~]# cd /usr/local/zabbix/sbin/
[root@localhost sbin]# ./zabbix_agentd

6、登录 Zabbix WEB 界面

Zabbix-WEB → configuration → hosts → Create host → Host name和Agent interfaces，同时选择添加templates模板 → 选择Add → 勾选Template OS Linux → 选择Add提交；

7、添加完模版，点击update，等待 Zabbix 连接

7、关闭防火墙，刷页面

[root@localhost sbin]# systemctl stop firewalld

五、中文字体乱码

1、上图可以看到设置成默认中午，查看图表时出现“□□”，其实是字体原因
2、我们需要找到本机的中午字体文件上传至服务器

3.上传图片中选中的字体上传至服务器

#zabbix4.3的字体目录
[root@izuf6gc1hiv72w66vyzv5iz fonts]# pwd
/data/nginx/html/zabbix/assets/fonts
[root@izuf6gc1hiv72w66vyzv5iz fonts]# ls
DejaVuSans.ttf  simkai.ttf

4、修改网页配置文件

[root@izuf6gc1hiv72w66vyzv5iz include]# pwd
/data/nginx/html/zabbix/include
[root@izuf6gc1hiv72w66vyzv5iz include]# cp defines.inc.php defines.inc.php.bak
[root@izuf6gc1hiv72w66vyzv5iz include]# vim defines.inc.php

69 define('ZBX_GRAPH_FONT_NAME',           'DejaVuSans'); // font file name   #原来
69 define('ZBX_GRAPH_FONT_NAME',           'simkai'); // font file name       #修改为

5、字体乱码问题变解决了
