SkyWalking搭建，JAVA和PHP的接入

搭建一个ES集群

详细搭建步骤这里就不详细描述了，可以参考官方的 安装文档。

安装skywalking服务

1、下载解压skywalking

$ cd /data/download/
$ wget https://dlcdn.apache.org/skywalking/9.3.0/apache-skywalking-apm-9.3.0.tar.gz
$ tar zxvf apache-skywalking-apm-9.3.0.tar.gz
$ cd apache-skywalking-apm-bin

2、配置elasticsearch

$ vi ./config/application.yml

修改成下面的配置:

storage:
  selector: ${SW_STORAGE:elasticsearch} #指定采用什么存储，这里改成使用elasticsearch
  elasticsearch:
    namespace: ${SW_NAMESPACE:"runbany_erp"} # elasticsearch的集群名称
    clusterNodes: ${SW_STORAGE_ES_CLUSTER_NODES:10.100.0.30:9200,10.100.0.31:9200,10.100.0.32:9200} # elasticsearch节点信息
    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}

更多的配置说明请参考 官方配置

3、启动 SkyWalking OAP

$ ./bin/oapService.sh
SkyWalking OAP started successfully!

查看一下启动日志，确认是否启动成功

4、SkyWalking UI 启动

$ ./bin/webappService.sh
SkyWalking Web Application started successfully!

输入网址就可以访问了 http://127.0.0.1:8080/

Java接入SkyWalking

1、启动参数方式接入

# 下载Java Agent
$ cd /opt/
$ wget https://dlcdn.apache.org/skywalking/java-agent/8.13.0/apache-skywalking-java-agent-8.13.0.tgz
$ tar zxvf apache-skywalking-java-agent-8.13.0.tgz

# 启动脚本增加参数
$ java -DSW_AGENT_NAME=TEST -DSW_AGENT_COLLECTOR_BACKEND_SERVICES=127.0.0.1:11800 -DSW_AGENT_SPAN_LIMIT=2000 -DSW_AGENT_INSTANCE_NAME=$HOSTNAME -javaagent:/opt/skywalking-agent/skywalking-agent.jar -jar test.jar

2、IDEA参数调试

其实就是把启动的VM参数设置好，同步设置环境变量，这些变量java agent里面会用到，更多参数可以参考 官方配置说明

PHP接入SkyWalking

1、安装PHP扩展包

# 安装依赖包
$ yum install gcc make cargo clang protobuf-compiler

# perl安装
$ pecl install skywalking_agent

Build process completed successfully
Installing '/usr/lib64/php/modules/skywalking_agent.so'
install ok: channel://pecl.php.net/skywalking_agent-0.2.0
configuration option "php_ini" is not set to php.ini location
You should add "extension=skywalking_agent.so" to php.ini

错误：thread ‘main’ panicked at 'Unable to find libclang: "the libclang shared library at /usr/lib64/clang-private/libclang.so.7 could not be opened
解决：

$ rpm -qa | grep "llvm-private"
$ rpm -e --nodeps llvm-private-7.0.1-1.el7.x86_64
$ yum install -y clang llvm

错误：thread ‘main’ panicked at 'libclang function not loaded: clang_getTranslationUnitTargetInfo. This crate requires that libclang 3.9 or later be installed on your system, clang版本过低了，centos 7默认是3.4
解决：

$ yum install llvm-toolset-7
$ scl enable llvm-toolset-7 bash #激活clang并检查版本,clang相关依赖已经全部安装了

错误：Error: Custom { kind: Other, error: “protoc failed: language-agent/Tracing.proto:19:10: Unrecognized syntax identifier “proto3”. This parser only recognizes “proto2”.\n” } protobuf版本太低，centos7 YUM安装的是2.5
解决：

$ wget https://github.com/google/protobuf/releases/download/v3.6.1/protobuf-all-3.6.1.tar.gz
$ tar zxvf protobuf-all-3.6.1.tar.gz
$ cd protobuf-3.6.1/
$ ./autogen.sh
$ ./configure --prefix=/usr/local/protobuf
$ make
$ make install

$ vi /etc/profile

2、PHP配置

$ vim php.ini
[skywalking]
extension=skywalking_agent.so

# Enable skywalking extension or not.
skywalking_agent.enable = On

# Log file path.
skywalking_agent.log_file = /tmp/skywalking_agent.log

# Log level: one of `OFF`, `TRACE`, `DEBUG`, `INFO`, `WARN`, `ERROR`.
skywalking_agent.log_level = INFO

# Address of skywalking oap server.
skywalking_agent.server_addr = http://0.0.0.0:11800

# Application service name.
skywalking_agent.service_name = hello-skywalking

# Skywalking version.
skywalking_agent.skywalking_version = 9

# Skywalking worker threads, 0 will auto set as the cpu core size.
# skywalking_agent.worker_threads = 3

注：PHP必须是NTS版本，版本7.2及以上
