1. 环境准备

1.1. 用于搭建 SkyWalking 的三台服务器

1.1.1. 服务器

• 10.1.62.78
• 10.1.62.79

• 10.1.62.80

  1.1.2. 需要端口

• 11800（gRPC 数据收集和内网节点间通信）

• 12800（SkyWalking UI 查询和 HTTP 数据收集）

• 8080（SkyWalking UI 端口）

  1.1.3. 需要 JDK

  1.1.4. 创建 SkyWalking 用户

• 三台都要执行

  useradd skywalking
  passwd skywalking

1.2. Nacos 集群

• 10.1.62.78:8848
• 10.1.63.117:8848

• 10.1.63.118:8848

  1.3. ElasticSearch 集群

• 10.1.63.116:9200

• 10.1.63.116:9201

• 10.1.63.117:9200

  1.4. Nginx

• 10.1.62.78

  2. 安装过程

• 之后过程没有明确说明都在 10.1.62.78 上执行，用户为 skywalking 。

  2.1. 无密码 ssh 登录其他节点

• 执行命令 ssh-keygen -t rsa。

• 设置无密码登录。

  ssh-copy-id -p 19222 skywalking@10.1.62.78
  ssh-copy-id -p 19222 skywalking@10.1.62.79
  ssh-copy-id -p 19222 skywalking@10.1.62.80

2.2. 配置环境变量

2.2.1 创建环境变量脚本

cd /home/skywalking
cat > environment.sh << EOF
#!/usr/bin/bash
# SkyWalking 集群各机器 IP 数组
export SKYWALKING_NODE_IPS=(10.1.62.78 10.1.62.79 10.1.62.80)
export SKYWALKING_NODES="10.1.62.78:12800,10.1.62.79:12800,10.1.62.80:12800"
# Nacos 集群各机器 IP 及端口
export NACOS_NODE_IPS=(10.1.62.78 10.1.63.117 10.1.63.118)
export NACOS_NODE_PORTS=(8848 8848 8848)
export SW_CLUSTER_NACOS_HOST_PORT="10.1.62.78:8848,10.1.63.117:8848,10.1.63.118:8848"
# ES 集群名
export ELASTICSEARCH_NODE_IPS=(10.1.63.116 10.1.63.116 10.1.63.117)
export ELASTICSEARCH_NODE_PORTS=(9200 9201 9200)
export ELASTICSEARCH_CLUSTER_NAME="elasticsearch-cluster"
# ES 集群各机器 IP 及端口
export ELASTICSEARCH_CLUSTER_NODES="10.1.63.116:9200,10.1.63.116:9201,10.1.63.117:9200"
# ES 用户名
export ELASTICSEARCH_CLUSTER_USER="elastic"
# ES 密码
export ELASTICSEARCH_CLUSTER_PASSWORD="elastic"
EOF

2.2.2. 脚本分发到其他服务器

source /home/skywalking/environment.sh
for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    scp -P 19222 /home/skywalking/environment.sh skywalking@${node_ip}:/home/skywalking/
  done

2.3. 环境检测

2.3.1. Nacos 集群检测

source /home/skywalking/environment.sh
for i in "${!NACOS_NODE_IPS[@]}";
  do
    echo ">>> ${NACOS_NODE_IPS[$i]}"
    echo -e "\n" | telnet ${NACOS_NODE_IPS[$i]} ${NACOS_NODE_PORTS[$i]} | grep Connected
  done

2.3.2. ES 集群检测

source /home/skywalking/environment.sh
for i in "${!ELASTICSEARCH_NODE_IPS[@]}";
  do
    echo ">>> ${ELASTICSEARCH_NODE_IPS[$i]}:${ELASTICSEARCH_NODE_PORTS[$i]}"
    echo -e "\n" | telnet ${ELASTICSEARCH_NODE_IPS[$i]} ${ELASTICSEARCH_NODE_PORTS[$i]} | grep Connected
  done

2.4. 下载并解压 SkyWalking 官方包

2.4.1. 下载

mkdir /home/skywalking/Softwares
cd /home/skywalking/Softwares/
wget https://mirror.bit.edu.cn/apache/skywalking/8.1.0/apache-skywalking-apm-es7-8.1.0.tar.gz

2.4.2. 分发服务器

source /home/skywalking/environment.sh
for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    ssh -p 19222 skywalking@${node_ip} "mkdir /home/skywalking/Softwares"
    scp -P 19222 /home/skywalking/Softwares/apache-skywalking-apm-es7-8.1.0.tar.gz skywalking@${node_ip}:/home/skywalking/Softwares/
  done

2.4.3. 解压

source /home/skywalking/environment.sh

for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    ssh -p 19222 skywalking@${node_ip} "tar zxvf /home/skywalking/Softwares/apache-skywalking-apm-es7-8.1.0.tar.gz -C /home/skywalking/"
  done

2.5. SkyWalking OAP 搭建

2.5.1. 备份 OAP 配置文件

source /home/skywalking/environment.sh

for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    ssh -p 19222 skywalking@${node_ip} "mv /home/skywalking/apache-skywalking-apm-bin-es7/config/application.yml /home/skywalking/apache-skywalking-apm-bin-es7/config/application.yml.bak"
  done

2.5.2. 创建新的 OAP 配置文件

cd /home/skywalking/apache-skywalking-apm-bin-es7/config/
touch application.yml

2.5.3. 使用 vi 命令编辑 application.yml 文件，写入以下内容

• 如果缩进和注释有问题，配合 :set paste 、:set nopaste 命令写入。 ```yml

sed -i -e 's/##SW_ES_PASSWORD##/'${ELASTICSEARCH_CLUSTER_PASSWORD}'/g' application.yml

2.5.5. 分发 OAP 配置文件

source /home/skywalking/environment.sh

for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    scp -P 19222 /home/skywalking/apache-skywalking-apm-bin-es7/config/application.yml skywalking@${node_ip}:/home/skywalking/apache-skywalking-apm-bin-es7/config/
  done

2.5.6. 针对每台服务器的配置修改

source /home/skywalking/environment.sh

for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
    echo ">>> ${node_ip}"
    ssh -p 19222 skywalking@${node_ip} "sed -i -e 's/##SW_CLUSTER_NACOS_INTERNAL_COM_HOST##/'${node_ip}'/g' /home/skywalking/apache-skywalking-apm-bin-es7/config/application.yml"
  done

2.5.7. 启动 OAP 服务

source /home/skywalking/environment.sh

for node_ip in ${SKYWALKING_NODE_IPS[@]}
  do
