前言

本章将介绍Nginx监控安装

Nginx监控安装:Filebeat+ES+Grafana(全)

1. 安装Nginx / OpenResty

1.1 安装 OpenResty

VeryNginx 基于 OpenResty,所以你需要先安装它:

OpenResty安装前准备

  • Centos:yum install -y readline-devel pcre-devel openssl-devel gcc GeoIP-devel
  • Debian|Ubuntu:apt-get install libreadline-dev libncurses5-dev libpcre3-dev libssl-dev perl make build-essential libgeoip-dev
  • geoip-devel 为geoip模块所需要的基础库
●wget  https://openresty.org/download/openresty-1.11.2.1.tar.gz
●tar -zxvf openresty-1.11.2.1.tar.gz
●cd openresty-1.11.2.1
●./configure --with-luajit --with-pcre --with-http_gzip_static_module --with-http_realip_module --with-http_geoip_module --with-http_ssl_module --with-http_stub_status_module --prefix=/app/openresty
●make && make install
复制代码

VeryNginx 实际使用到了 OpenResty 中的这些模块

  • lua-nginx-module
  • http_stub_status_module
  • lua-cjson library

如果你不想安装 OpenResty,或者你已经有了一个正在工作的 Nginx,你也可以自己手动为 Nginx 编译安装这些模块

1.2 安装部署 VeryNginx

克隆 VeryNginx 仓库到本地, 复制 nginx.conf 和 VeryNginx 文件夹到 Nginx 的工作目录.

cd ~
git clone https://github.com/alexazhou/VeryNginx.git
rm -f /app/openresty/nginx/conf/nginx.conf
cp ~/VeryNginx/nginx.conf /app/openresty/nginx/conf/nginx.conf
# 创建 /app/openresty/nginx/waf/verynginx 目录
mkdir -p /app/openresty/nginx/waf/verynginx
# 把 /VeryNginx/verynginx 拷贝到 /app/openresty/nginx/waf/verynginx
cp -r ~/VeryNginx/verynginx /app/openresty/nginx/waf/verynginx

复制代码

1.3 编辑 Nginx 配置文件

VeryNginx 项目提供了一个配置模版 /app/openresty/nginx/conf。你需要把自己站点的 Nginx 配置加到这个模版里面。 但是记得不要修改配置 VeryNginx 的那部分代码(除非你知道自己在干啥 :smiling_imp: )。

接下来,说明配置文件有三点比较重要:

include /app/openresty/nginx/waf/verynginx/verynginx/nginx_conf/in_external.conf;
include /app/openresty/nginx/waf/verynginx/verynginx/nginx_conf/in_http_block.conf;

include /app/openresty/nginx/waf/verynginx/verynginx/nginx_conf/in_server_block.conf;
复制代码

in_http_block.conf z合格配置文件需要修改

upstream vn_upstream{
    server 127.0.0.1;
    balancer_by_lua_file /app/openresty/nginx/waf/verynginx/verynginx/lua_script/on_banlance.lua;
        keepalive 1024; #Connection pool
}

lua_package_path '/app/openresty/nginx/waf/verynginx/verynginx/lua_script/?.lua;;/app/openresty/nginx/waf/verynginx/verynginx/lua_script/module/?.lua;;';
lua_package_cpath '/app/openresty/nginx/waf/verynginx/verynginx/lua_script/?.so;;';
lua_code_cache on;

lua_shared_dict status 1m;
lua_shared_dict frequency_limit 10m;
lua_shared_dict summary_long 10m;
lua_shared_dict summary_short 10m;

init_by_lua_file /app/openresty/nginx/waf/verynginx/verynginx/lua_script/on_init.lua;
rewrite_by_lua_file /app/openresty/nginx/waf/verynginx/verynginx/lua_script/on_rewrite.lua;
access_by_lua_file /app/openresty/nginx/waf/verynginx/verynginx/lua_script/on_access.lua;
log_by_lua_file /app/openresty/nginx/waf/verynginx/verynginx/lua_script/on_log.lua;

复制代码

其他2个文件不要改变

配置 VeryNginx 的代码是下面这部分:

        }
    }

}

#---------------VeryNginx config code end-----------------
复制代码

如果不使用 VeryNginx 提供的配置模版,你也可以手动把这部分加入到自己的 Nginx 配置文件中. (如果安装路径不是/app/openresty ,需要对 lua_package_cpath 和 lua_package_path 的值进行修改)

1.4 启/停服务

启动服务: /app/openresty/nginx/sbin/nginx

停止服务:/app/openresty/nginx/sbin/nginx -s stop

1.5 配置VeryNginx

打开浏览器访问 http://127.0.0.1/VeryNginx/dashboard/index.html

默认用户名和密码:verynginx / verynginx 。

登录之后就可以查看状态,并对配置进行修改了。修改配置后,记得到 「配置 > 系统 > 全部配置」去保存.

提示

  • 通过 VeryNginx 控制面板保存新配置之后,会立刻生效,并不需要 restart/reload Nginx。

  • VeryNginx 把配置保存在 /app/openresty/nginx/waf/verynginx/configs/config.json 里面。

  • 如果因为配错了什么选项,导致无法登录,可以手动删除 config.json 来清空配置。

已安装成功openresty 可以用网盘的覆盖/app/openresty/nginx/waf目录

2. 安装elasticsearch

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.4.tar.gz
tar -zxvf  elasticsearch-6.5.4.tar.gz -C /usr/local/


useradd es
chown -R es:es /usr/local/elasticsearch-6.5.4/
cd /usr/local/elasticsearch-6.5.4
修改config/jvm.options为内存的一半大小
vi config/jvm.options  
-Xms512m 
-Xmx512m
修改 max file 和 max virtual memory 参数
用root 或 sudo 用户
vi /etc/sysctl.conf
添加下面配置:
vm.max_map_count=655360
并执行命令:
sysctl -p

配置端口 跨域
vi /usr/local/elasticsearch-6.5.4/config/elasticsearch.yml
cluster.name: elasticsearch
node.name: node-1
network.host: 0.0.0.0
http.port: 9200
node.max_local_storage_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"

切换es用户
su - es
在Elasticsearch主目录下运行下列命令来安装这些插件:
bin/elasticsearch-plugin install ingest-geoip
bin/elasticsearch-plugin install ingest-user-agent

es用户启动
/usr/local/elasticsearch-6.5.4/bin/elasticsearch -d
root用户启动
su - es -c '/usr/local/elasticsearch-6.5.4/bin/elasticsearch -d'

复制代码

2.1 windows 安装elasticseach-head

  • 访问 github.com/mobz/elasti… 下载 head 插件(选择 zip 压缩包下载方式)。

    下载 head 插件

  • 修改 ~\elasticsearch-6.6.2\elasticsearch-head-master\Gruntfile.js,在对应的位置加上 hostname:'*' 配置项。

    配置项

  • 在 ~\elasticsearch-6.6.2\elasticsearch-head-master 下执行 npm install 开始安装,完成后可执行 grunt server 或者 npm run start 运行 head 插件。

    运行 head 插件

  • 安装成功,访问 http://localhost:9100/。

    访问

2.2 注意事项

  • 在 head 中连接 ES 失败。
    连接 ES 失败

对于 Access-Control-Allow-Origin 的问题,可以在 ElasticSearch 6.x 的 ~\config\elasticsearch.yml 文件的末尾加入以下代码:

http.cors.enabled: true 
http.cors.allow-origin: "\*" 
node.master: true node.data: true
复制代码

配置更新后,重启 ES 即可连接成功。

3. 安装Filebeat

推荐博客:www.cnblogs.com/cjsblog/p/9…

wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.5.4-linux-x86_64.tar.gz
tar -zxvf  filebeat-6.5.4-linux-x86_64.tar.gz  -C /usr/local/
cd /usr/local/
mv filebeat-6.5.4-linux-x86_64 filebeat-6.5.4
cd /usr/local/filebeat-6.5.4
vi filebeat.yml
复制代码
filebeat.inputs:


- type: log

  enabled: false

  paths:
    - /app/openresty/nginx/logs/access.log


#============================= Filebeat modules ===============================

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml

  reload.enabled: false


setup.template.settings:
  index.number_of_shards: 3

setup.template.name: "nginx-log-"
setup.template.pattern: "nginx-log-*"
setup.template.overwrite: true





output.elasticsearch:
  enabled: true
  hosts: ["106.13.3.200:9200"]
  index: "nginx-log-%{+yyyy-MM-dd}"


#================================ Processors =====================================

# Configure processors to enhance or manipulate events generated by the beat.

processors:
  #- add_host_metadata: ~
  #- add_cloud_metadata: ~
  - drop_fields:
        fields: ["beat.name", "beat.version", "host.architecture","host.architecture","host.name","beat.hostname","log.file.path"]
复制代码

3.1 启用模块nginx

cd /usr/local/filebeat-6.5.4/modules.d
vi  nginx.yml 

复制代码

执行以下配置

- module: nginx
  # Access logs
  access:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/app/openresty/nginx/logs/access.log"]

  # Error logs
  error:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/app/openresty/nginx/logs/error.log"]
复制代码

3.2 配置 default.json

cd /usr/local/filebeat-6.5.4/module/nginx/access/ingest vi default.json
