postfix安装（二）-- apache
安装apache有点曲折，主要是apr导致的安装包： httpd-2.4.1.tar.bz2
下载地址：http://www.apache.org
首先要定义一个完整的主机名 ：
否则在启动apache的时候会有这样的报错：
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using ::1. Set the 'ServerName' directive globally to suppress this message
编辑 /etc/sysconfig/network 文件，然后重启才能生效
开始安装
]# chmod +x httpd-2.4.1.tar.bz2
]# tar jxf httpd-2.4.1.tar.bz2
]# cd httpd-2.4.1
]# ./configure --prefix=/usr/local/apache
checking for APR... no
configure: error: APR not found.Please read the documentation.
发现没有安装apr相关包，然后就用yum批量安装
]# yum install apr apr-util apr-devel apr-util-devel apr-util-mysql -y
再次运行configure出现这个报错：
checking for pcre-config... false
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
解救措施就是安装pcre相关包
]# yum install pcre pcre-devel pcre-static -y
]# rpm -qa |grep pcre
pcre-7.8-3.1.el6.x86_64
pcre-devel-7.8-3.1.el6.x86_64
]# make
rotatelogs.c:(.text+0x5ed): undefined reference to `apr_file_link'
collect2: ld returned 1 exit status
make: *** Error 1
检查apr包是否已经安装，事实证明已经安装过了
# rpm -qa |grep apr
apr-1.3.9-3.el6.x86_64
apr-util-1.3.9-3.el6.x86_64
apr-devel-1.3.9-3.el6.x86_64
apr-util-devel-1.3.9-3.el6.x86_64
apr-util-ldap-1.3.9-3.el6.x86_64
试了几次都是同样的报错，把rpm包都卸载了，安装apr源码包
apr-1.3.8.tar.gz
apr-util-1.3.8.tar.gz
安装apr-util的时候需要指定apr的路径 --with-apr=/usr/local/apr
重新安装apache
./configure --prefix=/usr/local/apache --with-apr-util=/usr/local/apr-util
在make install的时候，SB错误又出现了
.libs/rotatelogs.o: In function `post_rotate':
/home/software/httpd-2.4.1/support/rotatelogs.c:298: undefined reference to `apr_file_link'
collect2: ld returned 1 exit status
看来不是apr包的问题了，难道是哪个地方没有配置么 ？
]# ./configure --prefix=/usr/local/apache/ --with-apr=/usr/local/apr/bin/apr-1-config --with-lib=/usr/local/apr/lib/ --with-apr-util=/usr/local/apr-util/
再续！！！！
今天又回来继续这个问题
我把apr和apr-util全都make clean然后删掉安装路径相关的文件/usr/local/apr
在apache官方网站上重新下载的apr包 apr-util包和httpd包
http://mirror.bit.edu.cn/apache//apr/
apr-1.4.5.tar.gz
apr-util-1.3.8.tar.gz
http://mirror.bit.edu.cn/apache//httpd/
httpd-2.4.1.tar.gz
在中途中除了遇到这样一个蹩脚错误，我也不知道什么原因导致的，就用yum install libtool -y 就ok了
info.lo -lrt -lcrypt-lpthread
libtool: link: `strings/apr_strings.lo' is not a valid libtool object
make: *** 错误 1
# libtool: link: `strings/apr_strings.lo' is not a valid libtool object
make: *** 错误 1
make: Leaving directory `/home/software/apr-1.4.5'
make: *** 错误 1
重新整理一下安装思路：
安装环境：
]# yum install libtool apr apr-util apr-devel apr-util-devel apr-util-mysqlpcre pcre-devel pcre-static -y
安装apr
./configure --prefix=/usr/local/apr
make && make install
安装apr-util
./configure --with-apr=/usr/local/apr
make && make install
安装http
./configure --prefix=/usr/local/apache--with-apr=/usr/local/apr/bin/apr-1-config --with-lib=/usr/local/apr/lib
make && make install
如果apr和apr安装完整的话，再安装http，应该没问题，我觉得我的apr和apr-util没有安装完整
功夫不负有心人哟，O(∩_∩)O
-------------------------------------------------------
]# cp /home/software/httpd-2.4.1/support/apachectl /etc/init.d/httpd
开机自启动
将service httpd start 加入文件 /etc/rc.d/rc.local
启动服务
]# service httpd start
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using ::1. Set the 'ServerName' directive globally to suppress this message
]# ps aux |grep http

另外chkconfig不支持httpd，那么可以用以下方式实现开机自动启动：
]# vi /etc/init.d/httpd 在#/bin/sh下加入下列两行
#chkconfig:2345 57 57
#description:Apache
PS:开头必须得加#，要不然还是不支持chkconfig
]# ln -s /etc/init.d/httpd /etc/rc.d/rc2.d/S57httpd
]# ln -s /etc/init.d/httpd /etc/rc.d/rc53d/S57httpd
]# ln -s /etc/init.d/httpd /etc/rc.d/rc4.d/S57httpd
]# ln -s /etc/init.d/httpd /etc/rc.d/rc5.d/S57httpd
]# chkconfig --add httpd
]# chkconfig --list |grep httpd
检测服务
然后在本机的浏览器地址栏中输入localhost:80，看一下是否显示“It Works”的提示
