在CentOS上配置Nginx和SSL以优化性能是一个多方面的过程,涉及到硬件、软件配置、网络设置等多个方面。以下是一些基本的优化建议:
server {
listen 443 ssl http2;
...
}
http {
keepalive_timeout 65;
...
}
http {
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
...
}
server {
listen 443 ssl;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA';
ssl_prefer_server_ciphers on;
...
}
sudo sysctl -w net.ipv4.tcp_syncookies=1
sudo sysctl -w net.core.somaxconn=4096
sudo sysctl -w fs.file-max=65536
sudo sysctl -w net.ipv4.tcp_congestion_control=bbr
server {
listen 80;
keepalive_timeout 65;
...
}
通过上述优化措施,可以显著提高CentOS上Nginx和SSL的性能。请注意,这些建议需要根据具体的环境和资源进行调整。
