优化Debian LAMP中Apache性能可从以下方面入手:
event或worker模块(需禁用prefork):sudo a2dismod prefork && sudo a2enmod event && sudo systemctl restart apache2 event模块需设置StartServers、MinSpareThreads、MaxSpareThreads、ThreadsPerChild(如:ThreadsPerChild 25,MaxRequestWorkers 150)。prefork模块需设置StartServers、MinSpareServers、MaxSpareServers、MaxRequestWorkers。KeepAlive并调整超时时间(建议10-30秒):KeepAlive On KeepAliveTimeout 10 MaxKeepAliveRequests 50 MaxConnectionsPerChild限制单个进程处理请求数(如设为1000,防止内存泄漏)。ulimit或cgroups限制Apache进程的文件描述符和内存使用。mod_cache和mod_deflate缓存静态内容并压缩传输(节省带宽和服务器负载)。/etc/sysctl.conf,如增加文件描述符限制、优化TCP缓冲区:fs.file-max = 100000 net.ipv4.tcp_max_syn_backlog = 4096 注意:修改配置后需重启Apache服务,并通过htop、ab等工具监控性能,根据实际负载调整参数。
