为了追求极致的网站速度,但是又由于环境受限,我无法使用OpenLightSpeed、Nginx等web服务器替代Apache,因此只能在现有环境下想想怎么才能优化。注:本文仅作笔记,可能结构比较乱,望各位理解。
1 未提到的
- Google PageSpeed: 已专门写过文章: https://www.i45s.com/new_archives/27.shtml。
- Varnish: AMH自带,因为我有其他中转服务,更改一下上游端口即可直接经过Varnish缓存服务。
- APCu: AMH自带,直接安装即可。
- PHP插件 OPCache:PHP8(我使用php8.3)开始支持JIT加速。
- PHP.ini:分配内存等配置项全部翻倍,超时时间给长一些
这些是在写文章就已经做好的了,并且没多大记下来的必要(操作比较简单),便一笔带过。
我使用的是AMH面板,配置目录在/usr/local/apache-2.4/conf
。
2 MPM配置提升
多处理模块默认给的配置较低,也许是年代比较久,对于目前的服务器配置性能往往是过剩的。
MPM配置文件在conf/extra/httpd-mpm.conf
中,首先对其进行备份。
只需修改三处配置,其他的都是别的系统(如WinNT OS/2 NetWare)的,我的Linux服务器用不到这些,当然你可以删除,我这里以防万一就不删了。下面给出我的原始配置文件:

# Server-Pool Management (MPM specific)

# identification number when it starts.

# Note that this is the default PidFile for most MPMs.
#
<IfModule !mpm_netware_module>
PidFile "logs/httpd.pid"
</IfModule>
#

# installed httpd. Use "apachectl -l" to find out the
# active mpm.

这是修改后的,给StartServers之类的配置全部提升了:

保存,前往面板重启Web服务。理论上,目前Apache的并发性能应该提升了一个档次。
性能测试
此处使用apache benchmark进行测试。
在进行1、2节优化后
已经差不多利用了服务器的全部性能了(12核cpu),进行测试由于提供的数值太大,耗时太长,后面还是取消了,不知这样是否有参考价值,以后会注意一些(第一次用这玩意测嘛)
总之,这一个小站,自己访问下来,速度不错,也懒得管那么多了,就这样吧。
优化还是得有的,生活在于折腾~ 以后慢慢更新啦~
