A Linux environment Apache installation configuration failure error, compiler failed solution, Apache installation upgrade Opsenssl steps __linux

1, ready to install the program:

Apr-1.6.2.tar.gz

Apr-util-1.6.0.tar.gz

Expat-2.2.4.tar.bz

Httpd-2.4.27.tar.gz

Openssl-1.1.0f.tar.gz

Pcre-8.41.tar.gz

2, in turn decompression:

TAR-XVF apr-1.6.2.tar.gz

TAR-XVF apr-util-1.6.0.tar.gz

TAR-XVF expat-2.2.4.tar.bz

TAR-XVF httpd-2.4.27.tar.gz

TAR-XVF pcre-8.41.tar.gz

3. Installation OpenSSL

TAR-XVF openssl-1.1.0f.tar.gz 
cd openssl-1.1.0f
./config shared Zlib-dynamic--prefix=/usr/local/openssl Make make
install

After installation, if you have a history version of OpenSSL, you need to deal with

Mv/usr/bin/openssl/usr/bin/openssl.bak
Mv/usr/include/openssl/usr/include/openssl.bak

New so file soft connection, here need to pay attention to find the address of so file to know the address of the soft link

For example, some people are

Ln-s/usr/lib64/libssl.so.1.1/usr/local/lib64/libssl.so.1.1 

But I found out that my server failed, so I looked for the so address

Find/-name "libssl.so.1.1"

The installation address is found to be different:

[root$tgpmsidc39 lib64]# Find/-name "libssl.so.1.1"
/soft/openssl-1.1.0f/libssl.so.1.1
/usr/local/openssl /lib/libssl.so.1.1

So obviously, our order should be modified to:

Ln-s/usr/local/openssl/lib/libssl.so.1.1/usr/lib64/libssl.so.1.1
ln-s/usr/local/openssl/lib/ libcrypto.so.1.1/usr/lib64/libcrypto.so.1.1

Let so effective, the specific principle please Google:

echo "/usr/lib64" >>/etc/ld.so.conf

Check to see if the path is written

[root$tgpmsidc39 lib64]# cat/etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib64

The file is written to take effect

Ldconfig–v

or Ldconfig–v |grep Libssl.

Some people perform ldconfig–v, will error, please modify add absolute path:

/sbin/ldconfig-v |grep Libssl

No problem if you have 1.1 version of so information

Install Apr

Tar  -xvzf  apr-1.6.2.tar.gz
cd apr-1.6.2
./configure--prefix=/usr/lcoal/apr
make Install

Install expat after decompression

Tar  -xvzf expat-2.2.4.tar.gz
cd expat-2.2.4
./configure make make
install

Install Apr-util

Tar  -xvzf apr-util-1.6.0.tar.gz
cd apr-util-1.6.0

The resolution steps are as follows:

./configure--prefix=/usr/local/apache2.4--enable-mods-shared=all  --with-ssl=/usr/local/openssl   -- With-apr-util=/usr/local/apr/bin/apu-1-config

Then make will not be an error, the installation will be successful.

Another installation of the other when the error can not find the APR
