Linux查看Java进程PID、端口号和内存占用脚本

news 2025/8/31 11:32:15

superJps - Java进程监控脚本

1. 功能概述

superJps是一个基于Bash的Java进程监控脚本，用于快速获取Linux系统中所有Java进程的详细信息。该脚本提供进程标识符(PID)、监听端口、内存占用和JAR路径/主类名称等关键信息，并附带系统级资源统计功能。

2. 核心功能

  • 进程信息展示：实时显示所有Java进程的PID、端口、内存占用和启动参数
  • 端口检测：自动识别进程监听的网络端口（未监听显示N/A）
  • 精确内存计算：基于/proc文件系统计算实际物理内存占用(RSS)
  • 资源统计：提供进程总数、端口监听数、内存总占用及系统内存占比

3. superJps 脚本

#!/bin/bash
export LC_ALL=C  # 确保数字格式标准化TMP_FILE_PATH=/tmp/superJps.tmp
jps -ml > "$TMP_FILE_PATH"TOTAL_MEM=$(free -m | awk '/Mem:/ {print $2}')  # 获取系统总内存(MB)
SUM_RSS=0  # 使用实际内存大小代替百分比
TOTAL_PROCESSES=0
PROCESSES_WITH_PORTS=0echo -e "PID\tPORT\tRSS(MB)\tJAR"while read -r LINE
doJPS_ARRAY=($LINE)PID=${JPS_ARRAY[0]}[ -z "$PID" ] && continue  # 跳过空行# 获取实际内存使用(RSS) - 更可靠的方法RSS_KB=$(awk '/Rss:/ {sum += $2} END {print sum}' /proc/$PID/smaps 2>/dev/null)if [[ $RSS_KB -gt 0 ]]; thenRSS_MB=$((RSS_KB / 1024))SUM_RSS=$((SUM_RSS + RSS_MB))elseRSS_MB=0fi# 获取监听端口PORT=$(ss -tulnp 2>/dev/null | awk -v pid="$PID" '$1 == "tcp" && $2 ~ /LISTEN/ && $NF ~ pid,"java" {split($5, a, ":");port = a[length(a)];if (port ~ /^[0-9]+$/) print port}' | head -1)# 统计信息((TOTAL_PROCESSES++))[ -n "$PORT" ] && ((PROCESSES_WITH_PORTS++))# 输出进程信息echo -e "$PID\t${PORT:-N/A}\t${RSS_MB}\t${JPS_ARRAY[*]:1}"done < "$TMP_FILE_PATH"# 显示统计摘要
echo "========================================"
echo "Java进程总数: $TOTAL_PROCESSES"
echo "带端口监听: $PROCESSES_WITH_PORTS"
echo "内存总占用: ${SUM_RSS}MB"
echo "系统总内存: ${TOTAL_MEM}MB"
echo "内存占比: $(awk "BEGIN {printf \"%.1f%%\", ${SUM_RSS}/${TOTAL_MEM}*100}")"

4. 实现原理

4. 1. 进程信息获取

jps -ml > "$TMP_FILE_PATH"

使用JDK自带的jps命令获取所有Java进程的详细信息，输出到临时文件以供处理。

4.2. 内存计算机制

RSS_KB=(awk '/Rss:/ {sum += 2} END {print sum}' /proc/$PID/smaps 2>/dev/null)

通过解析/proc/[pid]/smaps文件的Rss字段，累计计算进程的实际物理内存占用，比简单的top或ps命令更加准确。

4.3. 端口检测方法

ss -tulnp 2>/dev/null | awk -v pid="$PID" '1 == "tcp" && 2 ~ /LISTEN/ && $NF ~ pid,"java" {split($5, a, ":");port = a[length(a)];if (port ~ /^[0-9]+$/) print port}' | head -1

使用ss命令（替代netstat）检测网络连接，通过PID匹配筛选出Java进程监听的端口。

4.4. 统计功能

脚本实时统计：

  • 进程总数
  • 带端口监听的进程数量
  • 内存总占用（MB）
  • 系统总内存（MB）
  • 内存占比百分比

5. 使用方法

5.1 基本使用

vim /root/bin/superJps
# 复制 3. superJps 脚本 内容保存
vim /etc/profile
export PATH=$PATH:/root/bin
source /etc/profile

输出示例

[root@localhost bin]# superJps

========================================
Java进程总数: 181
带端口监听: 177
内存总占用: 51533MB
系统总内存: 92485MB
内存占比: 55.7%

配置说明

环境要求

  • Linux操作系统
  • JDK 1.6+（提供jps命令）
  • ss命令（通常由iproute2包提供）

安装部署

  1. 保存脚本至/root/bin/superJps
  2. 添加执行权限：chmod +x /root/bin/superJps
  3. 确保jps命令在PATH环境变量中

临时文件

脚本使用/tmp/superJps.tmp作为临时存储文件，会在执行完成后自动清理。

注意事项

  1. 需要root权限或对/proc目录有访问权限
  2. 内存统计排除共享内存，反映实际物理占用
  3. 端口检测仅显示首个监听端口
  4. 使用LC_ALL=C确保数字格式标准化
  5. 建议在相同语言环境的系统中使用

应用场景

  • Java应用故障排查
  • 服务器资源监控
  • 应用部署验证
  • 性能分析初步诊断

该脚本为系统管理员和开发人员提供了快速诊断Java应用状态的有效工具，结合了JDK工具和系统命令的优势，提供了比标准jps命令更丰富的监控信息。
