skywalking 部署教程

1.安裝JDK8：

因為oracle現在要同意協議才能下載，直接使用wget加鏈接下載不到，所以要加上前面的那些代碼：

#下載JAVA環境安裝包：
wget --no-check-certificate --no-cookie --header "Cookie: oraclelicense=accept-securebackup-cookie;" http://download.oracle.com/otn-pub/java/jdk/8u171-b11/512cd62ec5174c3487ac17c61aaa89e8/jdk-8u171-linux-x64.rpm

使用rpm -ivh jdk-8u171-linux-x64.rpm進行安裝

命令執行完畢即安裝完成，使用java -version 檢查是否安裝成功

 

2.部署Elasticsearch

在/etc/yum.repo.d/下新建elasticsearch.repo文件，內容如下：

[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

 按 :wq保存后執行sudo yum install elasticsearch -y安裝

用vim配置文件/etc/elasticsearch/elasticsearch.yml

• 設置 cluster.name: CollectorDBCluster。此名稱需要和collector配置文件一致。
• 設置 node.name: masterNode, 節點名稱可以設置為任意名字，如為集群模式，則每個節點名稱需要不同。
  增加如下配置

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#

cluster.name: CollectorDBCluster
network.host: 0.0.0.0
thread_pool.bulk.queue_size: 1000

#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: master
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructve_requires_name: true　　

啟動服務systemctl start elasticsearch.service

設為開機啟動systemctl enable elasticsearch.service

如果es 運行不成功報內存不夠可以設置內存：

sudo sysctl -w vm.max_map_count=262144

 

檢查下ES是否正常運行： curl localhost:9200 

3.部署collector

下載release的版本https://github.com/OpenSkywalking/skywalking-netcore/releases

#下載collector
wget https://github.com/OpenSkywalking/skywalking-netcore/releases/download/v0.1.0/apache-skywalking-for-netcore-0.1.tar.gz

#解壓
tar -xzvf  apache-skywalking-for-netcore-0.1.tar.gz

 

修改 /data/aimei/skywalking/collector/apache-skywalking-for-netcore-0.1/bin/webappService.sh 中的127.0.0.1為Server-01的IP地址，目前為10.0.1.250。

 最終腳本如下：

PRG="$0"
PRGDIR=`dirname "$PRG"`
[ -z "$WEBAPP_HOME" ] && WEBAPP_HOME=`cd "$PRGDIR/.." >/dev/null; pwd`

WEBAPP_LOG_DIR="${WEBAPP_HOME}/logs"
JAVA_OPTS=" -Xms256M -Xmx512M"
JAR_PATH="${WEBAPP_HOME}/webapp"

if [ ! -d "${WEBAPP_HOME}/logs" ]; then
    mkdir -p "${WEBAPP_LOG_DIR}"
fi

_RUNJAVA=${JAVA_HOME}/bin/java
[ -z "$JAVA_HOME" ] && _RUNJAVA=java

eval exec "\"$_RUNJAVA\" ${JAVA_OPTS} -jar ${JAR_PATH}/skywalking-webapp.jar \
         --server.port=8080 --collector.ribbon.listOfServers=10.0.1.250:10800 \
        2>${WEBAPP_LOG_DIR}/webapp.log 1> /dev/null &"

if [ $? -eq 0 ]; then
    sleep 1
        echo "Skywalking Web Application started successfully!"
else
        echo "Skywalking Web Application started failure!"
        exit 1
fi

　

修改/data/aimei/skywalking/collector/apache-skywalking-for-netcore-0.1/config/application.yml中的所有localhost為Server-01的IP地址，目前為10.0.1.250。

給腳本權限及運行

chmod 777 /data/aimei/skywalking/collector/apache-skywalking-for-netcore-0.1/bin/*.sh

#運行 啟動WebUI和Collector
/data/aimei/skywalking/collector/apache-skywalking-for-netcore-0.1//bin/startup.sh

 

4.查看監測

打開http://10.0.1.250:8080，查看監測情況

如果防火牆沒有開請開啟防火牆：

netstat -tnlp | grep 22 ---查看這個端口什么在

使用 vi /etc/sysconfig/iptables 編輯防火牆

systemctl restart iptables.service ----重啟防火牆

 

 

docker-compose 部署教程：

docker-compose up --build

chmod u+x *.sh  給start.sh 權限
