线程数优化 | |
Prefork优化的关键在于MaxClients与MaxRequestsPerChild。 | |
MaxClients最佳的值: | |
apache_max_process_with_good_perfermance < (total_hardware_memory /apache_memory_per_process ) * 2 | |
apache_max_process = apache_max_process_with_good_perfermance * 1.5 | |
计算httpd平均占用内存 | |
ps aux|grep -v grep|awk '/httpd/{sum+=$6;n++};END{print sum/n}' (kb) | |
显示每个进程占用了大约100M的内存,假设机器内存为32G,可拿出16G用于Apache。代入公式,得出 | |
apache_max_process_with_good_perfermance = 16 * 1024 * 1024 / | |
108468*2=309 | |
apache_max_process = 309 * 1.5=464 | |
