生产应用调用chrome进程崩溃分析

生产某个应用再处理图片抓图流程时，需要调用chrome应用执行相关操作，迁移到新环境之后总是提示流程处理失败，下面记录并分享下分析的过程。

查看message日志
[~]# dmesg -T |tail -200

发现应用chrome进程存在int3中断。

使用strace命令再次运行了一遍应用的处理流程，得到如下信息：

[~]# strace -f -tt -T -s10000 -o result.txt + 应用处理命令及参数

此处可以看到chrome进程产生了coredump

再次确认coredump

[~]# coredumpctl list -r
TIME                         PID  UID  GID SIG     COREFILE EXE                        SIZE
Fri 2024-11-01 09:11:58 CST 5233 1000 1000 SIGTRAP present  /opt/google/chrome/chrome 32.8M

查看chrome版本

[~]# /opt/google/chrome/google-chrome --version
Google Chrome 85.0.4183.102

因为是直接迁移过来的，怀疑缺少依赖，旧版本的chrome很难找到rpm安装，于是从goole官网下载新版安装拖到主机上安装

[~]# yum install google-chrome-stable-130.0.6723.91-1.x86_64.rpm

安装最新版本的chrome再将/opt/google/chrome替换为老版本，再次运行应用恢复正常。

只是大概记录下用到的命令和分析过程，供参考！
