DAY14: 课堂记录-Apache和LAMP架构–技术流ken
Apache介绍
:80 — 端口 http对应80端口，https对应443端口
默认发布目录：/var/www/html/
默认发布文件：index.html
默认端口：80
200：ok，请求下载成功
304：not modified，标识一个缓存的资源是否发生过更改
403：forbidden，表示客户端没有权限访问所请求的资源
404：Not Found，表示客户端所请求的资源不存在
500：Internal Server Error，服务器内部错误
502：Bad Gateway，代理服务器从上游服务器获取到的是伪响应
编译安装Apache(http)
1. 编译安装apr
第一步：上传相关的软件包
[root@ken ~]# ls
apr-1.5.2.tar.gz apr-util-1.5.4.tar.gz httpd-2.4.20.tar.gz
第二步：解压
[root@ken ~]# tar xf apr-1.5.2.tar.gz
[root@ken ~]# tar xf apr-util-1.5.4.tar.gz
[root@ken ~]# tar xf httpd-2.4.20.tar.gz
第三步：进入安排apr解压目录，进行编译
[root@ken ~]# cd arp- apr-1.5.2
[root@ken apr-1.5.2]# ./configure –prefix=/usr/local/apr
第四步：解决依赖
configure: error: no acceptable C compiler found in $PATH #提示缺少编译器
See `config.log’ for more details
[root@ken apr-1.5.2]# yum install gcc -y
第五步：继续编译
[root@ken apr-1.5.2]# ./configure –prefix=/usr/local/apr
第六步：安装
[root@ken apr-1.5.2]# make && make install
2. 编译安装apr-utils
第一步：进入并开始编译
[root@ken ~]# cd apr-util-1.5.4
[root@ken apr-util-1.5.4]# ls
aprutil.dep buckets config.layout encoding libaprutil.mak NOTICE uri
aprutil.dsp build configure export_vars.sh.in libaprutil.rc NWGNUmakefile xlate
aprutil.dsw buildconf configure.in hooks LICENSE README xml
aprutil.mak build.conf crypto include Makefile.in README.cmake
apr-util.pc.in build-outputs.mk dbd ldap Makefile.win renames_pending
apr-util.spec CHANGES dbm libaprutil.dep memcache strmatch
apu-config.in CMakeLists.txt docs libaprutil.dsp misc test
[root@ken apr-util-1.5.4]# ./configure –with-apr=/usr/local/apr –prefix=/usr/local/apr-util #需要制定apr位置
第二步：编译安装
[root@ken apr-util-1.5.4]# make && make install
3. 编译http
第一步：进入解压文件并开始编译
[root@ken httpd-2.4.20]# ./configure –prefix=/usr/local/httpd2.4 –with-apr=/usr/local/apr –with-apr-util=/usr/local/apr-util –enable-cache –enable-deflate –enable-ssl –enable-rewrite –with-mpm=event
第二步：解决依赖
依赖一：
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/ #提示缺少pcre
You have new mail in /var/spool/mail/root
[root@ken httpd-2.4.20]# yum install pcre pcre-devel -y
依赖二：
checking whether to enable mod_deflate… configure: error: mod_deflate has been requested but can not be built due to prerequisite failures
[root@ken httpd-2.4.20]# yum install openssl openssl-devel -y
第三步：安装
[root@ken httpd-2.4.20]# make && make install
编译安装的apache常用操作
在任何路径下执行apachectl:
[root@ken bin]# cat /etc/profile.d/httpd.sh
export PATH=/usr/local/httpd2.4/bin:$PATH
[root@ken bin]# export /etc/profile.d/httpd.sh
-bash: export: `/etc/profile.d/httpd.sh’: not a valid identifier
[root@ken bin]# source /etc/profile.d/httpd.sh
验证操作：
[root@ken bin]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:111 *:*
LISTEN 0 128 *:80 *:*
LISTEN 0 128 *:22 *:*

LISTEN 0 128 :::111 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*
[root@ken bin]# cd
[root@ken ~]# pwd
/root
[root@ken ~]# apachectl stop
[root@ken ~]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:111 *:*

Awesome read. I just passed this onto a buddy who was doing some research on that. He just bought me lunch since I found it for him! Thus let me rephrase: Thanx for lunch!
