1. lnmp搭建
安装后配置，修改nginx的主配置文件
[root@server ~]# vim /usr/local/nginx/conf/nginx.conf
.....
error_log logs/error.log;
#error_log logs/error.log notice; ##开启错误日志存放目录
#error_log logs/error.log info;
.....
//开启以匹配php结尾的网站模板
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; ##此处修改/scripts为$document_root
include fastcgi_params;
}
//修改server段内容为
#access_log logs/host.access.log main;
location / {
root html;
index index.php index.html index.htm; ##此处添加index.php即可
}
//在网页目录站点创建index.php的文件，写入php网页信息
[root@server ~]# cat > /usr/local/nginx/html/index.php <<EOF
> <?php
> phpinfo();
> ?>
> EOF
//检查配置文件语法是否有误，并重新加载配置文件
[root@server ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@server ~]# nginx -s reload
//验证
2. zabbix部署
环境说明：
| 环境 | IP | 要安装的应用 |
|---|---|---|
| 服务器 | 192.168.93.129 | lnmp架构 |
| 客户端 | 192.168.93.130 | zabbix agent |
2.1 zabbix服务端安装
# 安装依赖包
[root@server ~]# yum -y install net-snmp-devel libevent-devel
安装过程略....
# 下载zabbix
[root@server ~]# cd /usr/src/
[root@server ~]# wget https://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/4.0.3/zabbix-4.0.3.tar.gz
下载过程略....
# 解压
[root@server src]# tar xf zabbix-4.0.3.tar.gz
# 创建zabbix用户和组
[root@serversrc]# groupadd -r zabbix
[root@server src]# useradd -r -M -s /sbin/nologin -g zabbix zabbix
# 配置zabbix数据库
[root@server ~]# mysql -uroot -p

# 编译安装zabbix
[root@server mysql]# cd /usr/src/zabbix-4.0.3
[root@server zabbix-4.0.3]# ./configure --enable-server \

[root@server zabbix-4.0.3]# make install
2.2 zabbix服务端配置
# 修改服务端配置文件
# 设置数据库信息
[root@server ~]# ls /usr/local/etc/
zabbix_agentd.conf zabbix_agentd.conf.d zabbix_server.conf zabbix_server.conf.d
[root@server ~]# vim /usr/local/etc/zabbix_server.conf
....
DBPassword=zabbix123! //设置zabbix数据库连接密码
# 启动zabbix_server和zabbix_agentd
[root@server ~]# zabbix_server
[root@server ~]# zabbix_agentd
[root@server ~]# ss -antl

# 启动nginx status，在nginx.conf配置文件中添加以下内容
[rootserver zabbix-4.0.3]# vim /usr/local/nginx/conf/nginx.conf #

Active connections: 1
server accepts handled requests
8 8 4
Reading: 0 Writing: 1 Waiting: 0
## Active connections – 活跃的连接数量
## server accepts handled requests — 总共处理了1个连接 , 成功创建1次握手, 总共处理了1个请求
## Reading — 读取客户端的连接数
## Writing — 响应数据到客户端的数量
## Waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
# 设置zabbix/conf目录的权限，让zabbix有权限生成配置文件zabbix.conf.php

3. 配置网页界面
创建新主机：
主机名必须和刚刚自定义的主机名一致： Hostname=runtime
- 配置——主机——创建主机
添加监控项 - 配置——主机——监控项
- 配置以下配置其他保持默认
添加触发器 - 配置——主机——触发器
4. 验证
