Apache httpd 源碼安裝 提示APR錯誤 ：解決方法

Apache httpd 源碼安裝 提示APR錯誤

一、下載 HTTPD 源碼包

https://www.apache.org/

選擇 中國域名 cn 的站點：

找到httpd:

二、回到Linux CentOS 中 ,使用wget名令下載httpd壓縮包：

[root@magedu ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.38.tar.gz
    --2019-07-21 13:16:50--  https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.38.tar.gz
    Resolving mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)... 101.6.8.193, 2402:f000:1:408:8100::1
    Connecting to mirrors.tuna.tsinghua.edu.cn (mirrors.tuna.tsinghua.edu.cn)|101.6.8.193|:443... connected.
    HTTP request sent, awaiting response... 200 OK
    Length: 9187294 (8.8M) [application/x-gzip]

三、解壓 下載文件;

[root@magedu ~]# tar zxvf httpd-2.4.38.tar.gz 
            httpd-2.4.38/
            httpd-2.4.38/config.layout
            httpd-2.4.38/configure.in
            httpd-2.4.38/Makefile.win
            httpd-2.4.38/configure
            httpd-2.4.38/test/
            httpd-2.4.38/test/test_parser.c
            httpd-2.4.38/test/check_chunked
            httpd-2.4.38/test/make_sni.sh
            httpd-2.4.38/test/README
            httpd-2.4.38/test/test-writev.c
            httpd-2.4.38/test/test_limits.c
            httpd-2.4.38/test/tcpdumpscii.txt

四、在解壓以前，先安裝編譯器和開發工具包；

`   [root@magedu ~]# yum install gcc "Developent Tools"`

五、進到解壓的httpd目錄，查看 configure 的幫助信息

[root@magedu ~]# cd httpd-2.4.38/
    [root@magedu httpd-2.4.38]# ./configure --help

六、使用配置文件安裝

[root@magedu httpd-2.4.38]# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd
            checking for chosen layout... Apache
            checking for working mkdir -p... yes
            checking for grep that handles long lines and -e... /usr/bin/grep
            checking for egrep... /usr/bin/grep -E
            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: 
            configure: Configuring Apache Portable（移植） Runtime library（運行庫）...
            configure: 
            checking for APR... no
            configure: error: APR not found.  Please read the documentation.（錯誤：APR沒找到，請閱讀文檔）

提示報錯：
configure: error: APR not found. Please read the documentation.（錯誤：APR沒找到，請閱讀文檔）
提示沒有找到 APR，使用yum 來安裝，但安裝時必定要注意，提示要裝哪一個軟件，通常要在軟件的後面加上devel，也就是說要裝缺乏軟件的開發工具，好比這個提示apr，那就要裝 apr-devel：

#yum install apr-devel

安裝完成以後，再./configure；
特別注意，這個期間不能切換到其餘目錄中，整個安裝的過程必定要在這安裝軟件的根目錄中；

[root@magedu httpd-2.4.38]# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd
checking for APR-util... no
configure: error: APR-util not found.  Please read the documentation.

提示缺乏apr-util，接着安裝apr-util的開發版，即 apr-util-devel

root@magedu httpd-2.4.39]# yum install apr-util-devel
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Resolving Dependencies
--> Running transaction check
--> Processing Dependency: libdb-devel(x86-64) for package: apr-util-devel-1.5.2-6.el7.x86_64
--> Processing Dependency: libaprutil-1.so.0()(64bit) for package: apr-util-devel-1.5.2-6.el7.x86_64
--> Running transaction check
...

安裝完成以後，再./configure

[root@magedu httpd-2.4.38]# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd
checking for pcre-config... false
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

提示pcre報錯，再安裝pcre，這個pcre也得裝開發版，即安裝pcre-devel:

[root@magedu httpd-2.4.39]# yum install pcre-devel -y

安裝完成以後，再./configure

# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E
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: 
...
config.status: creating include/ap_config_auto.h
config.status: executing default commands
configure: summary of build options:

                 Server Version: 2.4.39
                 C compiler:     gcc -std=gnu99
                CFLAGS:           -pthread  
                CPPFLAGS:        -DLINUX -D_REENTRANT -D_GNU_SOURCE  
               LDFLAGS:           
                 LIBS:             
                 C preprocessor: gcc -E

終於成功了，使用echo$?檢查是否成功：

[root@magedu httpd-2.4.39]# echo $?
                    0

而後使用make

[root@magedu httpd-2.4.39]# make
Making all in srclib
make[1]: Entering directory `/soft/httpd-2.4.39/srclib'
make[1]: Leaving directory `/soft/httpd-2.4.39/srclib'
Making all in os

最後：make install
[root@magedu httpd-2.4.39]#make install

七、完成以後，配置PATH變量、man手冊，完成後，啓動服務，登錄地址，出現測試頁，則表示安裝成功；
