`vim /www/server/nginx/conf/proxy.conf` 那改进后的`proxy.conf`最后的结果是： ``` proxy_http_version 1.1; proxy_set_header Connection "Keep-Alive"; proxy_temp_path /www/server/nginx/proxy_temp_dir; proxy_cache_path /www/server/nginx/proxy_cache_dir levels=1:2 keys_zone=cache_one:20m inactive=1d max_size=5g; client_body_buffer_size 512k; proxy_connect_timeout 60; proxy_read_timeout 240; proxy_send_timeout 60; proxy_buffer_size 32k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; proxy_next_upstream error timeout invalid_header http_500 http_503 http_404 http_502; proxy_next_upstream_tries 1; proxy_cache cache_one; ``` 默认是这样子的： ``` proxy_temp_path /www/server/nginx/proxy_temp_dir; proxy_cache_path /www/server/nginx/proxy_cache_dir levels=1:2 keys_zone=cache_one:20m inactive=1d max_size=5g; client_body_buffer_size 512k; proxy_connect_timeout 60; proxy_read_timeout 60; proxy_send_timeout 60; proxy_buffer_size 32k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; proxy_next_upstream error timeout invalid_header http_500 http_503 http_404; proxy_cache cache_one; ```
