linux: 安装openssl

一，下载和安装

说明：编译安装openssl的原因是：

编译安装 PHP 7.4.33 报错：

make: *** [Makefile:749: ext/openssl/openssl.lo] Error 1

openssl下载

wget https://github.com/openssl/openssl/releases/download/OpenSSL_1_1_1w/openssl-1.1.1w.tar.gz

解压

tar -zxvf openssl-1.1.1w.tar.gz

配置

cd openssl-1.1.1w/
./config --prefix=/opt/openssl --shared 

编译和安装:

# make && make install

二，报错的处理:

报错信息:

./config --prefix=/opt/openssl --shared

解决:

# yum install -y perl

四，报错的处理之三

# ./bin/openssl help
./bin/openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

解决：

# ln -s /opt/openssl/lib/libssl.so.1.1 /lib64/libssl.so.1.1
# ln -s /opt/openssl/lib/libcrypto.so.1.1 /lib64/libcrypto.so.1.1 

测试效果:

# ./bin/openssl help
