apache进程模式和线程模式的切换(work线程 prefork 非线程或进程）
[root@robin ~]# vim /etc/sysconfig/httpd
HTTPD=/usr/sbin/httpd.worker
发布目录(默认)
[root@robin html]# cp -r /boot/ /var/www/html/ /boot 其他人必须具有 r权限
地址栏:http://172.16.110.1:80/boot
别名
vim /etc/httpd/conf/httpd.conf
alias /download /etc/
<directory /etc>
options indexes
</directory>
acl
alias /download /etc/ 前面是别名，后面是真实文件夹。两个都可以访问
<directory /etc>
options indexes
order deny,allow
deny from 172.16.110.30
allow from 172.16.110.31
</directory>
如果规则不冲突顺序匹配,如果规则冲突,从后往前读order,deny和allow那个选项在后边生效
验证登录
firefox /var/www/manual/index.html 调用firefox 网页
alias /download /etc/
<directory /etc>
options indexes
AuthType Basic 文件类型
AuthName "welcome to APACHE"
AuthBasicProvider file 验证类型
AuthUserFile /etc/httpd/conf/passwdb

</directory>
创建验证文件及用户
[root@robin manual]# htpasswd -c -b /etc/httpd/conf/passwdb aaa 123 -c 是创建文件 -b 是添加用户
[root@robin manual]# htpasswd -b /etc/httpd/conf/passwdb ccc 123

NTP服务器(时间服务器)
服务端:
vim /etc/ntp.conf 添加三行
restrict default nomodify notrap
server 127.127.1.0
fudge 127.127.1.0 stratum 10
service ntpd restart
客户端:需要关闭ntpd
[root@data1 html]# ntpdate 172.16.110.1
[root@data1 html]# crontab -e

笔记补充：
KeepAlive 保持链接 KeepAlive TimeOut 等待时间，然后4次挥手，每个子进程最大请求数400次，达到就要杀死，避免内存泄露 ThreadsPerChild 一进程对多线程
