Apache二进制免编译安装和参数配置
[*]下载http相关二进制软件包
cd /usr/local/src/
wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.34.tar.gz
wget http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz
wget http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz
说明：
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，可以很方便的从linux移植到windos
2.解压安装包
tar zxvfhttpd-2.4.34.tar.gz
tar zxvf apr-1.6.3.tar.gz
tar zxvfapr-util-1.6.1.tar.gz
3.编译安装 apr-1.6.3
cd apr-1.6.3
./configure --prefix=/usr/local/apr
报错01：
# ./configure --prefix=/usr/local/apr
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... x86_64-pc-linux-gnu

configure: error: in `/usr/local/apr-1.6.3':

See `config.log' for more details
# echo $?
1
解决办法：安装gcc
yum install gcc -y
再次config编译成功
# ./configure --prefix=/usr/local/apr
#make && make install
# echo $?
0
4.编译安装apr-util-1.6.1
cd /usr/local/src/apr-util-1.6.1
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install
编译安装报错
解决报错：安装expat库
yum install expat-devel -y
再次执行make && make install,报错解决
5.编译安装httpd-2.4.29
cd /usr/local/src/httpd-2.4.29
./configure \
--prefix=/usr/local/apache2.4 \
--with-apr=/usr/local/apr\
--with-apr-util=/usr/local/apr-util \
--enable-so \ ##支持动态扩展模块，apache支持以一个动态模块存在，Apache本身就是一个进程服务
--enable-mods-shared=most
编译报错01:configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
解决办法:
yum install pcre-devel -y
再次执行./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most返回如下界面,表示configure编译成功
注:如果在编译过程中出现，缺少某个依赖包，解决思路
yum list |grep 包
然后安装devel关键字的软件包
yum install -y 软件包
make && make install 编译安装报错
说明：缺少了xml相关的库，需要安装libxml2-devel包。直接安装并不能解决问题，因为httpd调用的apr-util已经安装好了，但是apr-util并没有libxml2-devel包支持
解决办法：
参考https://blog.csdn.net/MrDing991124/article/details/78829184
重新安装libxml2-devel
yum install -y libxml2-devel
删除apr-util软件包
rm -rf /usr/local/src/apr-util-1.6.1
cd /usr/local/src/
重新编译安装apr-util
tar zxvf apr-util-1.6.1.tar.gz
cd apr-util-1.6.1/
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install
# pwd
/usr/local/src/apr-util-1.6.1
# cd ..
#
# cd httpd-2.4.34
#
# ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most
返回下面界面说明configure这步编译成功
make && make install
返回下面界面说明make && make install 执行成功
root@server-1 httpd-2.4.29]# cd /usr/local/apache2.4/
# ls

说明：
bin目录：命令执行
conf目录：配置文件所在目录
htdocs目录：默认网站访问的内容就存在这个目录下
logs日志目录：访问日志，服务报错日志
modules目录：存放apache需要的模块
# ls ./modules/
# ls ./htdocs/

# ls ./bin/
# ls ./logs/
# ls ./conf/

查看apache服务状态，执行/usr/local/apache2.4/bin/apachectl命令后返回如下提示
# /usr/local/apache2.4/bin/apachectl
AH00558: httpd: Could not>
解决办法:
编译/usr/local/apache2.4/conf/httpd.conf文件,把参数 ServerName改为
ServerName localhost
注意:这里的localhost表示本机主机名,主机名可以自定义为其他
然后重启apache服务
# /usr/local/apache2.4/bin/apachectl restart
# /usr/local/apache2.4/bin/apachectl
httpd (pid 71429) already running
查看apache加载的模块
/usr/local/apache2.4/bin/httpd -M
说明: apache会加载两种类型的模块
static:静态模块
shared：动态模块
两者的区别在于，static模块是已经编译安装到/usr/local/apache2.4/bin/httpd配置文件中，而shared表示apache动态加载的模块
启动apache服务
/usr/local/apache2.4/bin/apachectl start
查看apache服务进程
# ps aux |grep httpd
