一、安装启动elasticsearch

1.修改主机名 node-1

2.下载软件包lasticsearch-7.17.0-linux-x86_64.tar.gz 并解压到/opt/

# curl -O http://192.168.200.3/cscc/iaas/elasticsearch-7.17.0-linux-x86_64.tar.gz
# tar -zxvf elasticsearch-7.17.0-linux-x86_64.tar.gz  -C /opt/
[root@node-1 elasticsearch-7.17.0]# mkdir data

3.修改Elasticsearch配置

[root@node-1 elasticsearch-7.17.0]# vi config/elasticsearch.yml
…
cluster.name: my-application
node.name: node-1
path.data: /opt/elasticsearch-7.17.0/data
path.logs: /opt/elasticsearch-7.17.0/logs
network.host: 0.0.0.0
cluster.initial_master_nodes: ["node-1"]
…
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

4.创建Elasticsearch启动用户，并设置属组及权限：

[root@node-1 elasticsearch-7.17.0]# groupadd elsearch
[root@node-1 elasticsearch-7.17.0]# useradd elsearch -g elsearch -p elasticsearch
[root@node-1 elasticsearch-7.17.0]# chown -R elsearch:elsearch /opt/elasticsearch-7.17.0/
[root@node-1 elasticsearch-7.17.0]# vi /etc/security/limits.conf 修改资源限制
* hard nofile 65536
* soft nofile 65536
[root@node-1 elasticsearch-7.17.0]# vi /etc/sysctl.conf
vm.max_map_count=262144
#reboot

5.启动Elasticsearch服务：

[root@node-1 ~]# cd /opt/elasticsearch-7.17.0/
[root@node-1 elasticsearch-7.17.0]# su elsearch
[elsearch@node-1 elasticsearch-7.17.0]$ ./bin/elasticsearch -d

6.查询端口，存在9200则成功启动：

[root@node-1 elasticsearch-7.17.0]# netstat -ntlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      598/rpcbind

tcp6       0      0 :::111                  :::*                    LISTEN      598/rpcbind         
tcp6       0      0 :::9200                 :::*                    LISTEN      2043/java 

访问ip:9200

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "Eq1Ix-j8TACU7EqHSE3-vg",
  "version" : {
    "number" : "7.17.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "bee86328705acaa9a6daede7140defd4d9ec56bd",
    "build_date" : "2022-01-28T08:36:04.875279988Z",
    "build_snapshot" : false,
    "lucene_version" : "8.11.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

二、部署SkyWalking OAP 服务

1.下载jdk 并配置

[root@node-1 ~]# curl -O http://192.168.200.3/cscc/iaas/jdk-8u144-linux-x64.tar.gz
[root@node-1 ~]# tar -zxvf jdk-8u144-linux-x64.tar.gz  -C /usr/local/
# vi /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_144
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
export PATH=$PATH:${JAVA_HOME}/bin

2.下载apache-skywalking-apm-es7-8.0.0.tar.gz解压/opt/

# tar -zxvf apache-skywalking-apm-es7-8.0.0.tar.gz -C /opt/

3.进入解压后目录，修改OAP配置文件

[root@node-1 apache-skywalking-apm-bin-es7]# vi config/application.yml
#集群配置使用单机版
cluster:
  selector: ${SW_CLUSTER:standalone}
  standalone:
…
#数据库使用elasticsearch7
storage:
  selector: ${SW_STORAGE:elasticsearch}
…
  elasticsearch:
    nameSpace: ${SW_NAMESPACE:""}
    clusterNodes: ${SW_STORAGE_ES_CLUSTER_NODES:192.168.200.18:9200}

4.启动OAP 查看端口11800 12800

[root@node-1 apache-skywalking-apm-bin-es7]# ./bin/oapService.sh 
SkyWalking OAP started successfully!

三. 部署SkyWalking UI服务

（1）由于SkyWalking UI的默认地址是8080，与很多中间件可能存在冲突，修改一下：
[root@node-1 apache-skywalking-apm-bin-es7]# vi webapp/webapp.yml
…
server:
  port: 8888
（2）启动SkyWalking UI服务：
[root@node-1 apache-skywalking-apm-bin-es7]# ./bin/webappService.sh 
SkyWalking Web Application started successfully!

四. 搭建并启动应用商城服务

1.切换节点修改主机名

hostnamectl set-hostname mall

修改/etc/hosts配置文件：

192.168.200.18 mall

2.下载gpmall.tar.gz

# tar -zxvf gpmall.tar.gz 
配置yum源
gpmall-repo

3.安装基础服务

安装基础服务，包括Java JDK环境、数据库、Redis、Nginx等

yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
yum install redis -y
yum install nginx -y
yum install mariadb-server -y

4.安装zookeeper服务并启动

tar -zxvf zookeeper-3.4.14.tar.gz 
cd zookeeper-3.4.14
mv zoo_sample.cfg zoo.cfg
./zkServer.sh start
cd gpmall
tar -zxvf kafka_2.11-1.1.1.tgz 
./kafka-server-start.sh -daemon ../config/server.properties 

5.启动服务

启动数据库

# vi /etc/my.cnf
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
systemctl start mariadb

设置root用户的密码为123456

[root@mall ~]# mysqladmin -uroot password 123456
[root@mall ~]# mysql -uroot -p123456

设置root用户的权限，命令如下：

grant all on *.* to root@localhost identified by '123456' with grant option;
grant all on *.* to root@'%' identified by '123456' with grant option;

将gpmall.sql文件上传至云主机的/root目录下。创建数据库gpmall并导入gpmall.sql文件。

MariaDB [(none)]> create database gpmall;
Query OK, 1 row affected (0.000 sec)
MariaDB [(none)]> use gpmall;
Database changed
MariaDB [gpmall]> source /root/gpmall/gpmall.sql;

启动redis

修改配置文件

[root@mall gpmall]# systemctl start redis
[root@mall gpmall]# systemctl enable redis

启动nginx

[root@mall gpmall]# systemctl start nginx
[root@mall gpmall]# systemctl enable nginx

（5）应用系统部署

使用提供gpmall-shopping-0.0.1-SNAPSHOT.jar、gpmall-user-0.0.1-SNAPSHOT.jar、shopping-provider-0.0.1-SNAPSHOT.jar、user-provider-0.0.1-SNAPSHOT.jar 、dist这5个包部署应用系统，其中4个jar包为后端服务包，dist为前端包。（包在gpmall目录下）

①全局变量配置
[root@mall ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.10 redis.mall
192.168.200.10 kafka.mall
192.168.200.10 mysql.mall
192.168.200.10 zookeeper.mall

②部署前端

rm -rf /usr/share/nginx/html/*
cp -vfr dist/* /usr/share/nginx/html/
[root@mall ~]# vi /etc/nginx/nginx.conf
…
  server {
      listen       80;
      listen       [::]:80;
      server_name _;
      root         /usr/share/nginx/html;
      location / {
      root   /usr/share/nginx/html;
      index index.html index.htm;
      }
      location /user {
          proxy_pass http://127.0.0.1:8082;
      }
      location /shopping {
          proxy_pass http://127.0.0.1:8081;
      }
      location /cashier {
          proxy_pass http://127.0.0.1:8083;
      }
systemctl start nginx

部署后端

将node-1节点的/opt/apache-skywalking-apm-bin-es7目录下的agent目录复制到mall节点下：

[root@mall ~]# scp -r 192.168.200.18:/opt/apache-skywalking-apm-bin-es7/agent /root/

修改SkyWalking agent配置文件

[root@mall ~]# vi agent/config/agent.config
…
agent.service_name=${SW_AGENT_NAME:my-application}
agent.sample_n_per_3_secs=${SW_AGENT_SAMPLE:1}
…
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:192.168.200.18:11800}

启动jar包

[root@mall ~]# nohup java -javaagent:/root/agent/skywalking-agent.jar -jar gpmall/shopping-provider-0.0.1-SNAPSHOT.jar &
[root@mall ~]# nohup: ignoring input and appending output to ‘nohup.out’
[root@mall ~]# nohup java -javaagent:/root/agent/skywalking-agent.jar -jar gpmall/user-provider-0.0.1-SNAPSHOT.jar &
[root@mall ~]# nohup: ignoring input and appending output to ‘nohup.out’
[root@mall ~]# nohup java -javaagent:/root/agent/skywalking-agent.jar -jar gpmall/gpmall-shopping-0.0.1-SNAPSHOT.jar &
[root@mall ~]# nohup: ignoring input and appending output to ‘nohup.out’
[root@mall ~]# nohup java -javaagent:/root/agent/skywalking-agent.jar -jar gpmall/gpmall-user-0.0.1-SNAPSHOT.jar &
[root@mall ~]# nohup: ignoring input and appending output to ‘nohup.out’
# httpd访问网络配置
[root@mall ~]# setsebool -P httpd_can_network_connect 1
