要提升Ubuntu Apache的并发能力,可以通过以下几种方法来优化和调整配置:
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5
MaxClients 150
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
<IfModule mpm_worker_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxRequestWorkers 150
MaxConnectionsPerChild 0
</IfModule>
<IfModule mpm_event_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxRequestWorkers 150
MaxConnectionsPerChild 0
</IfModule>
ulimit -n 65535
<IfModule mod_cache.c>
<IfModule mod_cache_disk.c>
CacheEnable disk /static
CacheRoot /var/cache/apache2/mod_cache_disk
CacheDirLevels 2
CacheDirLength 1
</IfModule>
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/html "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
</IfModule>
apachetop
、htop
、netdata
等来监控Apache的性能,并定期分析日志文件以识别瓶颈。在进行任何配置更改后,记得重启Apache服务以使更改生效:
sudo systemctl restart apache2
通过上述方法,你可以显著提高Apache在Ubuntu上处理高并发请求的能力。
