Apache二進制免編譯安裝和參數配置

1. 下載http相關二進制軟件包

   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

   說明：
   apr和apr-util是一個通用的函數庫，它讓httpd可以不關心底層的操作系統平臺，可以很方便的從linux移植到windos

2.解壓安裝包

tar zxvf  httpd-2.4.34.tar.gz
tar zxvf apr-1.6.3.tar.gz
tar zxvf  apr-util-1.6.1.tar.gz

3.編譯安裝 apr-1.6.3

cd apr-1.6.3
./configure --prefix=/usr/local/apr

報錯01：

[root@server-1 apr-1.6.3]# ./configure --prefix=/usr/local/apr
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu

configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
[root@server-1 apr-1.6.3]# echo $?
1

解決辦法：安裝gcc

yum install gcc -y

再次config編譯成功

[root@localhost apr-1.6.3]# ./configure --prefix=/usr/local/apr

[root@server-1 apr-1.6.3]#make && make install
[root@server-1 apr-1.6.3]# echo $?
0

4.編譯安裝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

編譯安裝報錯


解決報錯：安裝expat庫

yum install expat-devel -y

再次執行make && make install,報錯解決

5.編譯安裝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 \   ##支持動態擴展模塊，apache支持以一個動態模塊存在，Apache本身就是一個進程服務
--enable-mods-shared=most

編譯報錯01:configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解決辦法:
yum install pcre-devel -y

再次執行./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編譯成功

注:如果在編譯過程中出現，缺少某個依賴包，解決思路
yum list |grep 包
然後安裝devel關鍵字的軟件包
yum install -y 軟件包

make && make install 編譯安裝報錯

說明：缺少了xml相關的庫，需要安裝libxml2-devel包。直接安裝並不能解決問題，因爲httpd調用的apr-util已經安裝好了，但是apr-util並沒有libxml2-devel包支持
解決辦法：

參考https://blog.csdn.net/MrDing991124/article/details/78829184

重新安裝libxml2-devel

yum install -y libxml2-devel

刪除apr-util軟件包

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

重新編譯安裝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

[root@localhost apr-util-1.6.1]# pwd
/usr/local/src/apr-util-1.6.1
[root@localhost apr-util-1.6.1]# cd ..
[root@localhost src]#
[root@localhost src]# cd httpd-2.4.34
[root@localhost httpd-2.4.34]#
[root@localhost 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
返回下面界面說明configure這步編譯成功

make && make install
返回下面界面說明make && make install 執行成功

root@server-1 httpd-2.4.29]# cd /usr/local/apache2.4/
[root@server-1 apache2.4]# ls
bin  build  cgi-bin  conf  error  htdocs  icons  include  logs  man  manual  modules
說明：
bin目錄：命令執行
conf目錄：配置文件所在目錄
htdocs目錄：默認網站訪問的內容就存在這個目錄下
logs日誌目錄：訪問日誌，服務報錯日誌
modules目錄：存放apache需要的模塊
[root@server-1 apache2.4]# ls ./modules/

[root@server-1 apache2.4]# ls ./htdocs/
index.html
[root@server-1 apache2.4]# ls ./bin/

[root@server-1 apache2.4]# ls ./logs/
[root@server-1 apache2.4]# ls ./conf/
extra  httpd.conf  magic  mime.types  original

查看apache服務狀態，執行/usr/local/apache2.4/bin/apachectl命令後返回如下提示

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

解決辦法:
編譯/usr/local/apache2.4/conf/httpd.conf文件,把參數 ServerName改爲

ServerName localhost

注意:這裏的localhost表示本機主機名,主機名可以自定義爲其他
然後重啓apache服務

[root@localhost src]# /usr/local/apache2.4/bin/apachectl restart
[root@localhost src]# /usr/local/apache2.4/bin/apachectl
httpd (pid 71429) already running

查看apache加載的模塊

/usr/local/apache2.4/bin/httpd -M

說明: apache會加載兩種類型的模塊
static:靜態模塊
shared：動態模塊
兩者的區別在於，static模塊是已經編譯安裝到/usr/local/apache2.4/bin/httpd配置文件中，而shared表示apache動態加載的模塊

啓動apache服務

/usr/local/apache2.4/bin/apachectl start

查看apache服務進程
