skywalking安装遇到的错误以及解决
安装elasticsearch-6.5.4
在安装es之前先安装配置好jdk环境，这里使用了1.8
[root@kkkk bin]# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
配置正常能够访问，可能由于版本的问题，无法和skywalking 正常建立连接，页面返回500,后来使用elasticsearch-5.6.1正常
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.1.tar.gz
配置es
[root@kkkk config]# pwd
/opt/elasticsearch-5.6.1/config
[root@kkkk config]# ls
elasticsearch.yml jvm.options log4j2.properties scripts
[root@kkkk config]# vim elasticsearch.yml
cluster.name: myskywalking

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

http.port: 9200
启动es
useradd es
chown -R es.es /opt/elasticsearch-5.6.1/
[root@kkkk bin]# su es
[es@kkkk bin]$ ls
elasticsearch elasticsearch.in.sh elasticsearch-plugin elasticsearch-service-mgr.exe elasticsearch-systemd-pre-exec

elasticsearch.in.bat elasticsearch-keystore.bat elasticsearch-service.bat elasticsearch-service-x86.exe elasticsearch-translog.bat
[es@kkkk bin]$ cd /opt/
[es@kkkk opt]$ cd -
/opt/elasticsearch-5.6.1/bin
[es@kkkk bin]$ ./elasticsearch &
[1] 15808
[es@kkkk opt]$ ss -antp|grep java

下载好skywalking
https://archive.apache.org/dist/incubator/skywalking/5.0.0-beta2/apache-skywalking-apm-incubating-5.0.0-beta2.tar.gz
启动startup.sh发现只有8080端口是监听的10800，12800都是非监听状态
访问192.168.177.137:8080 页面显示500错误
是因为没有正确连接es的原因将skw主配置文件中的地址都改成了192.168.77.137

遇到的问题
1.启动es报错
ERROR: [1] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
ES报错
https://blog.csdn.net/cardinalzbk/article/details/54924511
修改文件最大描述符就可以解决
2.判断es是否正常启动
curl -XPUT http://101.201.115.106:9200
9200是http端口可以直接查看es是否启动成功
3.发现es莫名其妙被killd
es和skywalking都能正常运行，且端口监听正常，过一会es会被killd原因是内存太小了导致的,可以在/opt/elasticsearch-5.6.1/config/jvm.option做优化
4.两个500报错
1>更换了es版本改用5.X
2>将skw配置文件里的地址都改成了192.168.77.137
3>清理es的数据目录下的node下的所有文件
ps:webapp下的webapp.yml的地址也要修改
listOfServers: 192.168.77.137:10800
5.启动es报错解决
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
编辑 /etc/security/limits.conf，追加以下内容；
- soft nofile 65536
- hard nofile 65536
此文件修改后需要重新登录用户，才会生效
: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
编辑 /etc/sysctl.conf，追加以下内容：
vm.max_map_count=655360
保存后，执行：
sysctl -p
客户端配置
agent 端的配置开启探针
java -javaagent:/path/to/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=my-App -Dskywalking.collector.backend_service=localhost:11800 -jar myApp.jar
