Linux——安装apache

1. 检查机器是否已经安装了apache（系统自带）Centos6.5

rpm -qa |grep httpd

rpm -qa |grep apache

并检查/etc/httpd/httpd.conf 配置文件是否存在

如果存在则先卸载，或者关闭centos自带的web服务，执行chkconfig httpd off

并修改httpd的服务端口80为其他端口

2. 在官网下载对应的release
http://httpd.apache.org/
选择现在当前最新版本: httpd-2.4.25.tar.gz

3.将安装包拷贝到VM上并解压

tar -zxvf httpd-2.4.25.tar.gz 

4. 正常安装（另有安装一些相关插件会在后面补充）

进入httpd-2.4.25文件夹（cd httpd-2.4.25）

执行命令 

./configure --prefix=/usr/local/apache2

然后报错：（找不到apr）

checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... no
configure: error: APR not found.  Please read the documentation.

5. 处理apr问题
http://apr.apache.org/download.cgi 下载对应的安装包

以 apr-1.5.2.tar.gz 为例

和上段一致拷贝到文件夹下解压

tar -zxvf apr-1.5.2.tar.gz 

cd apr-1.5.2
./configure --prefix=/usr/local/apr

make
make install

成功后会出现很多文件安装   done 的字样
注意如果没有安装权限要sudo make/sudo make install

6. 处理apr-util问题

继续执行命令
[root@localhost httpd-2.4.25]# ./configure --prefix=/usr/local/apache2

出现以下报错

checking for chosen layout... Apache

checking for working mkdir -p... yes

checking for grep that handles long lines and -e... /bin/grep

checking for egrep... /bin/grep -E

checking build system type... x86_64-unknown-linux-gnu

checking host system type... x86_64-unknown-linux-gnu

checking target system type... x86_64-unknown-linux-gnu

configure:

configure:

  setting CPP to "gcc -E"

  setting CFLAGS to " -g -O2 -pthread"

  setting CPPFLAGS to " -DLINUX -D_REENTRANT -D_GNU_SOURCE"

  setting LDFLAGS to " "

configure:

configure: Configuring Apache Portable Runtime Utility library...

configure:

checking for APR-util... no

configure: error: APR-util not found.  Please read the documentation.

继续安装apr-util依赖包 （参照apr下载地址）

以 apr-util-1.5.4.tar.gz为例

命令和安装apr类似

tar -zxf apr-util-1.5.4.tar.gz

cd apr-util-1.5.4

./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config

make

make install

7.继续编译安装apache

如果继续按照上文

./configure --prefix=/usr/local/apache2 可能仍然报错没安装apr-util

可是老娘刚才已经装了撒！

执行

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

即可

编译的时候没有将apr-util路径加上他不认得罢了

继续，

[root@localhost httpd-2.4.25]# ./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/

在 http://pcre.org/ 安装pcre包

以pcre-8.40.tar.gz为例

tar -zxf pcre-8.40.tar.gz

cd pcre-8.40

./configure --prefix=/usr/local/pcre

make

make install

8.继续编译安装apache

cd httpd-2.4.25

./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre

make

make install

9.启动apache

/usr/local/apache2/bin/apachectl start

然后报错

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message

vim /usr/local/apache2/conf/httpd.conf

添加

将

#ServerName www.examda.com:80 

改为

ServerName localhost:80即可

保存退出

重新启动

/usr/local/apache2/bin/apachectl restart

还是不行（此时能ping通）

最终发现，将iptables（防火墙）关闭即可

service iptables stop

在浏览器输入VM的IP地址访问，It works!

以上。
