LAMP搭建2：Apache安装

34212131

1.进入/usr/local/src/目录下去下载Apache的安装包httpd-2.2.29.tar.gz
[iyunv@CentOS6 support-files]# cd /usr/local/src
[iyunv@CentOS6 src]# ls
httpd-2.2.9.tar.gz
2.解压安装包
[iyunv@CentOS6 src]# tar zxvf httpd-2.2.9.tar.gz
3.进入安装目录
[iyunv@CentOS6 src]# cd httpd-2.2.9
[iyunv@CentOS6 httpd-2.2.9]# ls

4.查看安装说明文件INSTALL可以看到安装步骤
……
$ ./configure --prefix=PREFIX
$ make
$ make install
$ PREFIX/bin/apachectl start
……
5.使用下面的参数配置安装选项，回车即可
[iyunv@CentOS6 httpd-2.2.9]# ./configure --prefix=/usr/local/apache2 --with-included-apr --enable-so --enable-deflate=shared --enable-expires=shared --enable-rewrite=shared --with-pcre
其中：
--prefix                                指定安装目录
--with-include-apr                依赖包apr，支持httpd，可以跨平台运作
--with-pcre                        正则相关的库
shared表示以动态共享的方式安装
有错改错，缺少什么库就安装：
如checking whether to enable mod_deflate... configure: error: mod_deflate has been requested but can not be built due to prerequisite failures
yum install  zlib-devel
6.直到配置没有问题然后开始编译
[iyunv@CentOS6 httpd-2.2.9]# echo $?
0
[iyunv@CentOS6 httpd-2.2.9]# make
7.编译没问题然后开始安装
[iyunv@CentOS6 httpd-2.2.9]# echo $?
0
[iyunv@CentOS6 httpd-2.2.9]# make install
8.安装成功
[iyunv@CentOS6 httpd-2.2.9]# echo $?
0
[iyunv@CentOS6 httpd-2.2.9]# ls /usr/local/apache2/
bin    cgi-bin  error   icons    lib   man     modules
build  conf     htdocs  include  logs  manual
9.现在还不能直接运行，需要编辑Apache主配置文件httpd.conf：
[iyunv@CentOS6 httpd-2.2.9]# vim /usr/local/apache2/conf/httpd.conf
将ServerName改为localhost:80，去掉前面的注释符#
……
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:80
……
10.将Apache加入系统环境变量：
[iyunv@CentOS6 support-files]# vim /etc/profile.d/path.sh
#!/bin/bash
export PATH=$PATH:/etc/init.d/:/usr/local/mysql/bin/:/usr/local/apache2/bin/
[iyunv@CentOS6 support-files]# source /etc/profile.d/path.sh
11.检查配置是否正确，正确则启动Apache
[iyunv@CentOS6 httpd-2.2.9]# apachectl -t
Syntax OK
[iyunv@CentOS6 httpd-2.2.9]# apachectl start
httpd (pid 22581) already running
12.查看Apache的进程和端口
[iyunv@CentOS6 httpd-2.2.9]# ps aux|grep httpd
[iyunv@CentOS6 httpd-2.2.9]# netstat -lnp
