Linux9.3 Apache安装

Apache是一个基金会的名字，httpd才是我们要安装的软件包，早期它的名字就叫apache
Apache官网www.apache.org

 

2.4源码包：wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.33.tar.gz

apr: wget http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz

apr-util: wget http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.bz2 

 

apr和apr-util是一个通用的函数库，它让httpd可以不关心底层的操作系统平台，可以很方便地移植（从linux移植到windows），2.4依赖apr。区别在于apr

 

tar zxf httpd-2.4.33.tar.gz

tar zxf apr-1.6.3.tar.gz

#如果发现无法解压，报错，可能需要安装yum install -y bzip2
tar jxf apr-util-1.6.1.tar.bz2

 　　编译安装apr

cd /usr/local/src/apr-1.6.3
./configure --prefix=/usr/local/apr
make && make install

　　编译安装apr-util

可以自定义模块安装

cd /usr/local/src/apr-util-1.6.1

 ./configure --prefix=/usr/local/apache2.4  --with-apr=/usr/local/apr

make && make install
cd /usr/local/src/httpd-2.4.33
./configure \ //这里的反斜杠是脱义字符，加上它我们可以把一行命令写成多行
--prefix=/usr/local/apache2.4 \
--with-apr=/usr/local/apr \
--with-apr-util=/usr/local/apr-util \
--enable-so \
--enable-mods-shared=most \
--with-included-apr

　　会报错

 

configure: error: Bundled APR requested but not found at ./srclib/. Download and unpack the corresponding apr and apr-util packages to ./srclib/.

错误为：apr，apr-util缺失，需要下载并解压到./srclib/目录下


解决办法

# cd /usr/local/src/
# cp -r apr-16.3 /usr/local/src/httpd-2.4.33/srclib/apr
# cp -r apr-util-1.6.1/usr/local/src/httpd-2.4.33/srclib/apr-util

 
再次执行./configure就不会报错，make，make install也不会报错；

 

　　

 

 

　　httpd核心二进制启动文件

[root@chy002 apache2.4]# du -sh ./bin/httpd
2.2M	./bin/httpd

　　配置文件

[root@chy002 apache2.4]# ls -l ./conf/httpd.conf 
-rw-r--r-- 1 root root 18236 3月   2 05:18 ./conf/httpd.conf

　　默认网站页放到该文件夹下

[root@chy002 apache2.4]# ls htdocs/
index.html

　　日志，错误日志访问日志

[root@chy002 apache2.4]# ls logs

　　httpd模块,查看所有模块

[root@chy002 apache2.4]# ls modules/
httpd.exp               mod_buffer.so               mod_log_config.so      mod_rewrite.so
mod_access_compat.so    mod_cache_disk.so           mod_log_debug.so       mod_sed.so
mod_actions.so          mod_cache.so                mod_logio.so           mod_session_cookie.so
mod_alias.so            mod_cache_socache.so        mod_macro.so           mod_session_dbd.so
... ...

[root@chy002 apache2.4]# /usr/local/apache2.4/bin/httpd -M
AH00557: httpd: apr_sockaddr_info_get() failed for chy002

　　其中，shared为扩展模块可在modules/中看到文件，static为固有模块

        /usr/local/apache2.4/bin/apachectl   该shell脚本调用了二进制文件httpd

　　启动脚本，虽然有错误，但是修改配置文件就可以解决

[root@chy002 apache2.4]# /usr/local/apache2.4/bin/apachectl start

想启动不出现这个错误，修改如下

#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:80


配置文件中的  ServerName localhost:80   前面注释去掉，把网站名称改为 localhost

 

安装过程报错：

1. ./configure报错

Configuring Apache Portable Runtime library ...

checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file.
解决办法:
下载安装
apr
apr-utils

 

2.configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解决办法：yum -y install pcre-devel

可以通过 yum list |grep pcre去搜索，因为报错中提到 libpcre说明是一个库，那么该软件包应该带有devel或者Lib字样。
