在CentOS上优化Apache的SSL性能,可从以下方面入手:
SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1 +TLSv1.3。SSLCipherSuite ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256。shmcb)并设置合理大小(如512000条目):SSLSessionCache shmcb:/var/run/apache2/ssl_scache(512000)。SSLUseStapling on。KeepAlive设置,减少TCP握手开销:KeepAlive On,MaxKeepAliveRequests 100,KeepAliveTimeout 5。ServerLimit和ThreadsPerChild参数。mod_deflate压缩静态资源(如HTML/CSS/JS):LoadModule deflate_module modules/mod_deflate.so。Header always set Strict-Transport-Security "max-age=63072000"。/var/log/httpd/),分析SSL握手耗时等指标。openssl s_client)测试SSL配置,确保兼容性与性能。注意:修改配置前需备份文件,测试环境验证后再应用到生产环境。
