通过docker搭建lamp+wordpress+ELK监控

实验要求：docker搭建LAMP +wordpress，有监控，日志放在另外一台服务器上， 使用ELK进行日志收集展示
192.168.100.128 lamp+kabana
192.168.100.129 docker-lamp +wordpress + logstash +zabbix-agent
192.168.100.130 zabbix + elasticsearch

一、配置环境

1.先进行安装docker

[root@localhost docker]# yum -y install docker

2.进行配置docker的加速镜像

[root@localhost docker]# cd /etc/docker/
[root@localhost docker]# vim daemon.json
{
"registry-mirrors": ["https://yol1de5p.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.100.128"]
}
~ 

docker进行启动和开机自启

[root@localhost docker]# systemctl start docker
[root@localhost docker]# systemctl enable docker

查看查看镜像是否可用

[root@localhost docker]# docker info

二、 拉去mysql和php镜像

[root@localhost docker]# docker pull mysql
[root@localhost docker]# docker pull php:7.2-apache

三、创建网络

[root@localhost docker]# docker network create lamp

查看网络

[root@localhost docker]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
f81b6f00fd07        bridge              bridge              local
3b6ec92601a8        host                host                local
9783e9b74d27        lamp                bridge              local
248da2b86740        none                null                local

四、创建生成mysql和php容器的脚本

先做个文件夹

[root@localhost ~]# mkdir mysql_php
[root@localhost ~]# cd mysql_php/

进行编写脚本

[root@localhost mysql_php]# vim docker_lamp.sh
#!/bin/bash

function mysql() {
    docker run --name mysql --net lamp -p 3306:3306 \
    -v /data/docker/mysql/data:/var/lib/mysql \
    -v /data/docker/mysql/conf:/etc/mysql/conf.d \
    -v /data/docker/mysql/logs:/logs \
    -e MYSQL_ROOT_PASSWORD=test123456 \
    -d mysql:latest --character-set-server=utf8
}

function httpd_php() {
    docker run --name httpd-php --net lamp -p 80:80 \
    -v /data/docker/httpd/conf:/etc/apache2/sites-enabled \
    -v /data/docker/www:/var/www/html \
    -v /data/docker/httpd/logs:/var/log/apache2 \
    -d php:7.2-apache
}

$1

启动mysql和php容器（启动容器之前首先关闭selinux【setenforce 0】）

[root@localhost mysql_php]# sh docker_lamp.sh mysql
dcaea8e2efe8832ac863d73c728f15799f57072e9b66174626a706ba9a51152b
[root@localhost mysql_php]# sh docker_lamp.sh httpd_php
52ff6c908d0d042030c9a535c55638566202cc9472bd873e0773279dad8b5f7c

查看容器

[root@localhost mysql_php]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                               NAMES
21f6d844d9e2        php:7.2-apache      "docker-php-entryp..."   About a minute ago   Up About a minute   0.0.0.0:80->80/tcp                  httpd-php
7bfa31aadbe1        mysql:latest        "docker-entrypoint..."   About a minute ago   Up About a minute   0.0.0.0:3306->3306/tcp, 33060/tcp   mysql

写一个php测试页进行测试

[root@localhost mysql_php]# echo "" > /data/docker/www/index.php
通过浏览器访问http://192.168.2.226

修改mysql密码加密方式为mysql_native_password

[root@localhost ~]# vim /data/docker/mysql/conf/docker_mysql.conf
[mysqld]
default-authentication-plugin=mysql_native_password

五、数据库操作

登陆mysql容器，创建、配置wordpress数据库

[root@localhost ~]# docker exec -it mysql /bin/bash
root@7bfa31aadbe1:/# mysql -uroot -ptest123456

mysql> create database wordpress;
mysql> create user wps@localhost identified by '123456';
mysql> grant all privileges on wordpress.* to wps@localhost;
mysql> create user [email protected] identified by '123456';
mysql> grant all privileges on wordpress.* to [email protected];
mysql> alter user [email protected] identified with mysql_native_password by '123456';
mysql> flush privileges;

六、配置wordpress博客系统

下载wordpress包并解压

wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
tar -zxvf wordpress-4.9.4-zh_CN.tar.gz -C /data/docker/www/

配置wordpress博客*

修改wp-config-sample.php配置

[root@localhost wordpress]# cd /data/docker/www/wordpress/
[root@localhost wordpress]# mv wp-config-sample.php wp-config.php 
[root@localhost wordpress]# vim wp-config.php    #修改以下内容


/ WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/ MySQL数据库用户名 */
define('DB_USER', 'wps');

/ MySQL数据库密码 */
define('DB_PASSWORD', '123456');

/ MySQL主机 */
define('DB_HOST', '172.18.0.1');

/ 创建数据表时默认的文字编码 */
define('DB_CHARSET', 'utf8');

/ 数据库整理类型。如不确定请勿更改 */
define('DB_COLLATE', '');

mysql容器里安装mysqli扩展

[root@localhost ~]# docker exec -it httpd-php /bin/bash
apt-get update
apt-get install libpng-dev
cd /usr/local/bin/
./docker-php-ext-install gd mysqli
./docker-php-ext-enable gd mysqli
exit
docker restart httpd-php（启动之后关闭防火墙）

修改wp-db.php文件，将mysql_connect替换为mysqli_connect

[root@localhost ~]# cd /data/docker/www/wordpress/
[root@localhost wordpress]# sed -i "s/mysql_connect/mysqli_connect/g" wp-includes/wp-db.php

之后通过浏览器测试 ：http://本机ip/wordpress 如果成功会出现一下界面

搭建配置zabbix

传入zabbix的源

[root@localhost ~]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# vim zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/$basearch/

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=0

在web端安装zabbix-agent并设置开机自启

[root@localhost yum.repos.d]# yum -y install zabbix-agent

[root@localhost yum.repos.d]# vim /etc/zabbix/zabbix_agentd.conf

Server=192.168.100.130

ServerActive=192.168.100.130

[root@localhost yum.repos.d]# systemctl start zabbix-agent

[root@localhost yum.repos.d]# systemctl enable zabbix-agent

在服务端安装zabbix服务和mysql

[root@localhost yum.repos.d]# yum -y install mariadb mariadb-server zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get

启动mysql并设置开机自启

[root@localhost yum.repos.d]# systemctl start mariadb
[root@localhost yum.repos.d]# systemctl enable mariadb

配置mysql

[root@localhost yum.repos.d]# mysql
MariaDB [(none)]> create database zabbix charset utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all on *.* to zabbix@localhost identified by 'zabbix';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.01 sec)

测试登录mysql的zabbix用户

[root@localhost yum.repos.d]# mysql -uzabbix -h localhost -pzabbix

查看一下zabbix的服务

[root@localhost ~]# ll /usr/share/doc/zabbix-server-mysql-4.4.8/create.sql.gz 
-rw-r--r--. 1 root root 1476658 4月  27 18:21 /usr/share/doc/zabbix-server-mysql-4.4.8/create.sql.gz

导入数据

[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql-4.4.8/create.sql.gz | mysql -uzabbix -pzabbix -hlocalhost zabbix

登录数据库并且查看数据

[root@localhost ~]# mysql
MariaDB [zabbix]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| zabbix             |
+--------------------+
5 rows in set (0.00 sec)

MariaDB [zabbix]> show tables;
+----------------------------+
| Tables_in_zabbix           |

| alerts                     |
| application_discovery      |
| application_prototype      |

修改zabbix的配置文件

[root@localhost ~]# vim /etc/zabbix/zabbix_server.conf
DBPassword=zabbix

启动zabbix和httpd的相关服务并设置开机自启

[root@localhost ~]# systemctl enable httpd zabbix-server zabbix-agent
[root@localhost ~]# systemctl start httpd zabbix-server zabbix-agent

查看端口

[root@localhost ~]# netstat -nlpt | grep -E "80|10050|10051"
tcp        0      0 0.0.0.0:10050           0.0.0.0:*               LISTEN      14225/zabbix_agentd 
tcp        0      0 0.0.0.0:10051           0.0.0.0:*               LISTEN      15590/zabbix_server 
tcp6       0      0 :::10050                :::*                    LISTEN      14225/zabbix_agentd 
tcp6       0      0 :::10051                :::*                    LISTEN      15590/zabbix_server 
tcp6       0      0 :::80                   :::*                    LISTEN      14281/httpd

修改时间并启动httpd

[root@localhost ~]# vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
[root@localhost ~]# systemctl restart httpd

上传修改字体防止乱码

[root@localhost ~]# cd /usr/share/zabbix/assets/fonts/
[root@localhost fonts]# ls
graphfont.ttf  simkai.ttf
[root@localhost fonts]# rm -rf graphfont.ttf 
[root@localhost fonts]# mv simkai.ttf graphfont.ttf

其浏览器查看ip/zabbix


一直下一步到这个界面
密码是：zabbix

通过服务端的get工具映射80端口如果是1 那么zabbix搭建成功

[root@localhost fonts]# zabbix_get -s 192.168.100.129 -k net.tcp.listen[80]
1

通过配置对lamp进行监控

通过tar包搭建ELK

在zabbix的服务端
安装jdk

[root@localhost ELK]# rpm -ivh jdk-8u131-linux-x64_.rpm 

解压elasticsearch的tar包

[root@localhost ELK]# tar xf elasticsearch-7.7.0-linux-x86_64.tar.gz 
[root@localhost ELK]# mv elasticsearch-7.7.0 /usr/local/elasticsearch

创建一个elasticsearch数据存储目录，并赋予elk用户拥有所属权限

[root@localhost src]# groupadd elk
[root@localhost src]# useradd -g elk elk -m
[root@localhost src]#  chown -R elk.elk /usr/local/elasticsearch/
[root@localhost elk]#  ll /usr/local/elasticsearch/

-rw-r--r--.  1 elk elk   8165 5月  12 09:58 README.asciidoc

创建一个elasticsearch数据存储目录，并赋予elk用户拥有所属权限

[root@localhost elk]# mkdir -p /data/elasticsearch
[root@localhost elk]# chown -R elk.elk /data/elasticsearch

修改elasticsearch配置文件,记得先备份一下配置文件再修改

[root@localhost src]# cd /usr/local/elasticsearch/config/
[root@localhost config]# cp elasticsearch.yml elasticsearch.yml.bak
[root@localhost config]# vim elasticsearch.yml
cluster.name: ELK-Cluster
node.name: node-1
path.data: /data/elasticsearch
path.logs: /usr/local/elasticsearch/logs
network.host: 192.168.100.130
http.port: 9200
cluster.initial_master_nodes: ["node-1"]

修改相关内核参数

[root@localhost config]# echo "vm.max_map_count=262144" >> /etc/sysctl.con
[root@localhost config]# sysctl -p 
[root@localhost config]# vim /etc/security/limits.conf
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536

切换用户elk来运行elasticsearch

[root@localhost config]# su - elk
[elk@localhost ~]$ cd /usr/local/elasticsearch/
[elk@localhost elasticsearch]$ ./bin/elasticsearch -d

如果启动出现max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
ERROR: Elasticsearch did not exit normally - check the logs at /usr/local/elasticsearch/logs/ELK-Cluster.log
的错误 可以以下操作

[elk@localhost elasticsearch]$ su root
[root@localhost elasticsearch]# sysctl -w vm.max_map_count=655360
vm.max_map_count = 655360
[root@localhost elasticsearch]# sysctl -a | grep "vm.max_map_count" 
看看可否输出655360在进行上一步的启动

检查elasticsearch状态，如下则表示正常运行

[elk@localhost elasticsearch]$ curl http://192.168.100.130:9200
{
  "name" : "node-1",
  "cluster_name" : "ELK-Cluster",

    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

logstash配置安装（docker端）

安装jdk

[root@localhost ELK]# rpm -ivh jdk-8u131-linux-x64_.rpm 

解压logstash

[root@localhost ELK]# tar xzvf logstash-7.7.0.tar.gz 
[root@localhost ELK]# mv logstash-7.7.0 /usr/local/logstash

修改配置文件

[root@localhost ELK]# cd /usr/local/logstash/config/
[root@localhost config]# vim httpd.conf
input {
    file {
        path => ["/data/docker/httpd/logs/other_vhosts_access.log"]
        type => "httpd-log"
        start_position => "beginning"
    }
}
output {
    elasticsearch {
        hosts => ["192.168.100.130:9200"]
        index => "httpd_log-%{+YYYY.MM.dd}"
    }
}

指定配置文件运行logstash

[root@localhost bin]# cd /usr/local/logstash/bin/
[root@localhost bin]#  ./logstash -f /usr/local/logstash/config/httpd.conf &
[root@localhost bin]# netstat -lntup |grep 9600

安装配置kibana

安装jdk

[root@localhost src]# rpm -ivh jdk-8u131-linux-x64_.rpm

解压到/usr/local并重命名为kibana

[root@localhost src]# tar xzvf kibana-7.7.0-linux-x86_64.tar.gz
[root@localhost src]# mv kibana-7.7.0-linux-x86_64 /usr/local/kibana

修改配置文件

[root@localhost config]# cd /usr/local/kibana/config/
[root@localhost config]# vim kibana.yml
server.port: 5601
server.host: "192.168.100.128"
elasticsearch.hosts: ["http://192.168.100.130:9200"]
logging.dest: /var/log/kibana.log

给/var/log/kibana.log文件加权限

[root@localhost config]# touch /var/log/kibana.log
[root@localhost config]# chmod 777 -R /var/log/kibana.log

进入安装目录下/bin启动kibana

[root@localhost config]# cd /usr/local/kibana/bin/
[root@localhost bin]# ./kibana --allow-root &
[root@localhost bin]# netstat -nlpt | grep 5601
