-
修改操作系统内核参数
vim /etc/sysctl.conf # 添加以下配置项 * soft core unlimit * hard core unlimit * soft fsize unlimited * hard fsize unlimited * soft data unlimited * hard data unlimited * soft nproc 65535 * hard nproc 63535 * soft stack unlimited * hard stack unlimited * soft nofile 409600 * hard nofile 409600
-
启动 Skywalking
/usr/local/apache-skywalking-apm-8.6.0/bin/startup.sh
- 配置日志自动清理
编写shell脚本, /data/skywalking/log_rotate.sh
```shell
#!/bin/bash
# 初始化
LOGS_PATH=/usr/local/apache-skywalking-apm-8.6.0/logs
for file in $LOGS_PATH/*
do
if test -f $file
then
echo $file
#find $file -mtime +15 -name '*[0-9]*-[0-9]*-[0-9]*' | xargs rm -f
else
find $file -mtime +15 -name '*[0-9]*-[0-9]*-[0-9]*' | xargs rm -f
fi
done
exit 0
```
- 添加脚本到 crontab 中, 每晚 00:00 自动执行, 清理 15 天之前的日志记录
# 执行 crontab -e # 输入 1 0 * * * /data/skywalking/log_rotate.sh
- 使用方法
spring boot程序接入, 参考 [Spring Boot应用部署文档](./Spring Boot应用部署文档.md)
# 启动springboot程序时指定 -javaagent 即可
nohup java -javaagent:/application/skywalking-agent/skywalking-agent.jar -Dskywalking.trace.ignore_path=/actuator/** -Dskywalking.agent.service_name=bjgyol-gateway -Dskywalking.collector.backend_service=192.159.51.13:11800 -jar -Dspring.profiles.active=prod /application/bjgyol-gateway.jar
tomcat 程序接入
# 第一步: 进入 tomcat/bin 目录, 修改 catalina.sh 启动脚本, 添加一行启动配置
CATALINA_OPTS="$CATALINA_OPTS -javaagent:/application/skywalking-agent/skywalking-agent.jar"
# 第二步: 进入 /application/skywalking-agent/config 目录，修改 agent.config 文件，修改以下几个配置项
# 1、默认
agent.service_name=${SW_AGENT_NAME:""}
# 修改为
# agent.service_name=${SW_AGENT_NAME:"bjgyol-gateway"}
# 2、 默认
# collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:""}
# 修改为 Skywalking 地址
# collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:192.159.51.13:11800}
# 第三步启动tomcat即可
