Monit-基于非容器服务自恢复程序实践
1.需求：因为历史原因和软件程序原因，有上百台服务和所在服务未运行在容器中，需要在程序奔溃自动拉起(以Java Python C++为主)。2.目的：能够非人为干预快速自动恢复，要求检测频率在10s一次
3.实现方式
3.1 根据不同语言自己开发脚本实现自动拉起和通知(不够标准化-弃用)
1 #!/bin/bash
2
3 # ========== 使用说明 ==========
4 # 1. 自定配置env: fat/prod等环境变量, nacos地址, lark webhook等
5 # 2. 确保每个Java服务有对应的启动脚本（如 deploy-xxx.sh）
6 # 3. 设置需要监控的Java服务列表（见下方SERVICES_PROCESS_ID等变量）
7 # 4. 将此脚本添加到crontab中定期执行，例如每1分钟检测一次monitor是否在运行，如果在运行不会重复运行，不在运行则会后台运行：
8 # */1 * * * * /bin/bash /path/to/this/monitor.sh >> /path/to/monitor.log 2>&1
9
10 # ========== 环境变量加载 ==========
11 # 在 crontab 中执行时，需要显式加载环境变量
12 # 按优先级加载多个可能的环境变量文件
13 ENV_FILES=(
14 "/etc/profile"
15 "/etc/bashrc"
16 "/root/.bash_profile"
17 "/root/.bashrc"
18 "$HOME/.bash_profile"
19 "$HOME/.bashrc"
20 )
21
22 for env_file in "${ENV_FILES[@]}"; do
23 if [ -f "$env_file" ]; then
24 echo "[$(date '+%Y-%m-%d %H:%M:%S')] 加载环境变量文件: $env_file" >> /tmp/monitor_env.log
25 source "$env_file"
26 fi
27 done
28
29 # 如果上述文件都没有加载到关键环境变量，则手动设置
30 if [ -z "$JAVA_HOME" ]; then
31 export JAVA_HOME="/opt/jdk-17.0.8"
32 export CLASSPATH=".:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar"
33 export PATH="$JAVA_HOME/bin:$PATH"
34 echo "[$(date '+%Y-%m-%d %H:%M:%S')] 手动设置 JAVA_HOME: $JAVA_HOME" >> /tmp/monitor_env.log
35 fi
36
37 # 设置必要的环境变量
38 export env_nacos_address="nacos.test.com:8848"
39 export env_nacos_namespace="fat"
40 export ENV="fat"

42 # 记录环境变量状态（用于调试）
