How to install apache server in linux

Compressed package installation method

1. Download httpd-2.4.29.tar.gz

2. Upload to server/usr/local/software

tar -zxvf httpd-2.4.29.tar.gz
./configure --prefix=/usr/local/apache2/ # 设置apache安装目录

If Apr has not been installed, an error will be reported:

checking for APR... no
configure: error: APR not found.  Please read the documentation.

3. Next, install apr, first download apr- 1.6.3.tar.gz

4. Upload to server/usr/local/software

tar -zxvf apr-1.6.3.tar.gz
cd apr-1.6.3
.configure
make
make install

An error will be reported again:

checking for APR-util... no
configure: error: APR-util not found.  Please read the documentation.

5. Download apr-util-1.6 .1.tar.gz

6. Upload to server/usr/local/software

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

At this time, an error will be reported:

xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录
 #include <expat.h>
                   ^
编译中断。
make: *** [xml/apr_xml.lo] 错误 1

7. It is speculated that expat may be missing. Development library

yum install expat-devel # 中间会让你输入y
./configure --prefix=/usr/local/apr-util/ --with-apr=/usr/local/apr
make # 成功！
make install

8. At this time, go back to install apache. Not only must you specify the path of apr, but also the path of apr-util

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

Still reporting errors, many people may come here. It has crashed, but this error is similar to the one encountered before

checking for pcre-config... false
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

9. Download pcre-8.41.tar.gz

10. Upload to the server/usr/local/software

tar -zxvf pcre-8.41.tar.gz
./configure

reported an error again, I guarantee this is the last time

checking windows.h usability... no
checking windows.h presence... no
checking for windows.h... no
configure: error: You need a C++ compiler for C++ support.

10. Install the c environment

yum install -y gcc gcc-c++
# 错了那么多次，别忘了现在的位置，接下来还是要安装pcre
./configure
make
make install

11. Okay, it’s been a big circle, and the next step is to install it apache

cd ..
cd apache
./configure --prefix=/usr/local/apache2/  --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/
make
make install

is so miserable! Another error was reported in the last step:

/usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_GetErrorCode'  
/usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_SetEntityDeclHandler'  
/usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_ParserCre
collect2: error: ld returned 1 exit status
make[2]: *** [htpasswd] 错误 1
make[2]: Leaving directory `/usr/local/software/apache/support'
make[1]: *** [all-recursive] 错误 1
make[1]: Leaving directory `/usr/local/software/apache/support'

I have never seen this kind of error before, so I searched online and found the answer: the apr version is too high;

12. So I downloaded apr-util- 1.5 http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz

13. Upload to server/usr/local/software

tar -zxvf apr-util-1.5.2.tar.gz
cd apr-util-1.5.2
./configure --prefix=/usr/local/apr-util-1.5/ --with-apr=/usr/local/apr
make
make install

14. Repeat step 11. The only difference is that the configuration now specifies: apr-util-1.5. This is very important! ! !

cd ..
cd apache
./configure --prefix=/usr/local/apache2/  --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util-1.5/
make # make时间会比较长
make install

Perfect ending:

Installing configuration files
mkdir /usr/local/apache2/conf
mkdir /usr/local/apache2/conf/extra
mkdir /usr/local/apache2/conf/original
mkdir /usr/local/apache2/conf/original/extra
Installing HTML documents
mkdir /usr/local/apache2/htdocs
Installing error documents
mkdir /usr/local/apache2/error
Installing icons
mkdir /usr/local/apache2/icons
mkdir /usr/local/apache2/logs
Installing CGIs
mkdir /usr/local/apache2/cgi-bin
Installing header files
mkdir /usr/local/apache2/include
Installing build system files
mkdir /usr/local/apache2/build
Installing man pages and online manual
mkdir /usr/local/apache2/man
mkdir /usr/local/apache2/man/man1
mkdir /usr/local/apache2/man/man8
mkdir /usr/local/apache2/manual
make[1]: Leaving directory `/usr/local/software/apache'

15. Enter the configuration file location: /usr/local/apache2/conf

cp httpd.conf httpd.conf.bak    # 备份配置文件
vim httpd.conf
# 放掉191行的注释，修改为：
ServerName [你的IP]:80
:wq

16. Start apache

/usr/local/apache2/bin/apachectl start
# 或者
/usr/local/apache2//bin/httpd -k start

Turn off the firewall, enter the server IP in the browser address bar, and the web page will appear: It works!

17. Close apache

ps -ef|grep apache
/usr/local/apache2/bin/apachectl stop
# 或者
/usr/local/apache2//bin/httpd -k stop
# 没错，bin前面就是//

This method of original file installation is too complicated. In fact, There is another way to install the apache service. I don’t know if it conflicts with my previous installation. I will try it today.

yum source installation method

1. yum source installation (requires Internet download)

首先关闭apache服务
yum install httpd # 中间过程中输入：y

Result:

Installed as a dependency:

  apr.x86_64 0:1.4.8-3.el7_4.1      
  apr-util.x86_64 0:1.5.2-6.el7        
  httpd-tools.x86_64 0:2.4.6-67.el7.centos.6      
  mailcap.noarch 0:2.1.41-2.el7        
完毕！

2. The installation location of yum is: /etc/httpd/conf. After I entered it, I backed up the configuration file first. The modified place is different from before, in line 95. For reference only

cd /etc/httpd/conf
cp httpd.conf httpd.conf.bak
# 放掉95行的注释，修改为：
ServerName [你的IP]:80
:wq

3. Start the service

systemctl start httpd.service

Enter the ip in the browser, and the html preset by apache will appear, perfect! ! !

4. Close the service

systemctl stop httpd.service

5. I started the httpd installed in the first way again

/usr/local/apache2/bin/apachectl start

Refresh the browser and the message: It works!, It shows that there is no conflict between the two installation methods.
