Elasticsearch
修改配置文件
# 设置不需要ce认证可以根据场景选择这里我选择取消
# xpack.security.enabled: true
xpack.security.enabled: false添加用户
# 添加用户
adduser elasticsearch# 设置文件权限
chown -R elasticsearch:elasticsearch /opt/elasticsearch运行
# 设置后台运行
sh elasticsearch -c /opt/elasticsearch/elasticsearch-8.5.3/bin/elasticsearch -d第一次运行会显示

• On this node:⁃ Create an enrollment token with bin/elasticsearch-create-enrollment-token -s node.⁃ Uncomment the transport.host setting at the end of config/elasticsearch.yml.⁃ Restart Elasticsearch.
• On other nodes:⁃ Start Elasticsearch with bin/elasticsearch --enrollment-token token, using the enrollment token that you generated.

配置Elasticsearch服务
vim /usr/lib/systemd/system/elasticsearch.service# 服务文件内容
[Unit]
Descriptionelasticsearch service
Aftersyslog.target network.target rc-local.service[Service]

ExecStop/bin/sh -c /bin/kill -s TERM $MAINPID

WantedBymulti-user.target# 杀死正在运行Elasticsearch程序
ps -ef | grep elasticsearch# 杀死查询到的pidxxx填写是ps -ef查到的内容
kill xxx# 配置服务
systemctl daemon-reload
systemctl restart elasticsearch.service
systemctl enable elasticsearch.service# 查询服务状态
systemctl status elasticsearch.service修改默认密码
Elasticsearch修改密码有两种第一种是用http请求的方式第二种是使用bin目录下的可执行文件操作具体的可以搜下相关文章
skywalking
修改oap服务配置文件
# 编辑配置application.yml文件
vim /opt/skywalking/apache-skywalking-apm-bin/config/application.ymlstorage:selector: ${SW_STORAGE:elasticsearch} # 选择ES存储elasticsearch:namespace: ${SW_NAMESPACE:skywalking-index} # 命名空间#namespace: ${SW_NAMESPACE:elasticsearch}clusterNodes: ${SW_STORAGE_ES_CLUSTER_NODES:localhost:9200} # 节点地址多个用,逗号间隔protocol: ${SW_STORAGE_ES_HTTP_PROTOCOL:http}connectTimeout: ${SW_STORAGE_ES_CONNECT_TIMEOUT:3000}socketTimeout: ${SW_STORAGE_ES_SOCKET_TIMEOUT:30000}responseTimeout: ${SW_STORAGE_ES_RESPONSE_TIMEOUT:15000}numHttpClientThread: ${SW_STORAGE_ES_NUM_HTTP_CLIENT_THREAD:0}user: ${SW_ES_USER:elastic} # 账号password: ${SW_ES_PASSWORD:76B6UvSrcp1N5dX3nuq*} # 密码更改安装好的ES信息storage.selector存储方式使用elasticsearch、storage.elasticsearch.namespace命名空间根据个人喜好填写、storage.elasticsearch.clusterNodesES集群节点地址、storage.elasticsearch.userES账号、storage.elasticsearch.passwordES密码。
修改ui配置文件
# 编辑配置application.yml文件
vim /opt/skywalking/apache-skywalking-apm-bin/wabapp/application.yml修改内容
# 避免冲突将默认的8080修改为12880
serverPort: ${SW_SERVER_PORT:-12880}运行服务
# 单独运行oap服务
/opt/skywalking/apache-skywalking-apm-bin/bin/oapService.sh# 单独运行webappUI
/opt/skywalking/apache-skywalking-apm-bin/bin/webappService.sh# 直接运行等于运行oap服务与webapp服务
/opt/skywalking/apache-skywalking-apm-bin/bin/startup.sh查看日志是否运行成功
oap服务日志位置/opt/skywalking/apache-skywalking-apm-bin/logs/skywalking-oap-server.log、webapp服务日志位置/opt/skywalking/apache-skywalking-apm-bin/logs/skywalking-webapp.log
打开ui地址http://192.168.254.130:12880就会出现安装好后的界面啦注意这里192.168.254.130是我安装的服务器地址12880是webapp配置文件中配置的端口。
agent探针
/opt/skywalking/skywalking-agent/skywalking-agent.jar是探针的jar包使用java -jar运行jar包时添加参数-javaagent:/opt/skywalking/skywalking-agent/skywalking-agent.jaragent.service_nameOS_Gateway,collector.backend_service192.168.1.80:11800例 nohup java -Xms8G -Xmx8G -XX:MetaspaceSize512M -XX:MaxNewSize512m -XX:MaxMetaspaceSize1G -XX:HeapDumpOnOutOfMemoryError -XX:HeapDumpPathheapdump.hprof -XX:PrintGCDetails -Xloggc:loggc-apic.log -javaagent:/opt/skywalking/skywalking-agent/skywalking-agent.jaragent.service_nameOS_Gateway,collector.backend_service192.168.1.80:11800 -jar ${jar_name} ${log_name} 21
