CentOS 7升级OpenSSL
旧版本openssl1.0.2k新版本openssl1.1.1
安装所需环境
yum install wget vim gcc gcc-c++ zlib zlib-devel
下载主程序
wget -c -P /opt/tmp/ https://www.openssl.org/source/openssl-1.1.1.tar.gz
解压缩
cd /opt/tmp/
tar zxvf openssl-1.1.1.tar.gz
cd opensll-1.1.1
配置程序安装目录
./config shared zlib --prefix=/usr/local/openssl --openssldir=/usr/local/openssl/ssl
显示配置数据
perl configdata.pm --dump
编译安装
make -j 4
make install
查看新安装版本
cd /usr/local/openssl/bin
./openssl version -a
此处显示错误，说明找到不libssl.so.1.1库
./openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
查看新版本openssl关联的动态库
ldd openssl
linux-vdso.so.1 =>(0x00007fff12142000)
libssl.so.1.1 => not found
libcrypto.so.1.1 => not found
libz.so.1 => /lib64/libz.so.1 (0x00007f702c2e5000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f702c0e1000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f702bec5000)
libc.so.6 => /lib64/libc.so.6 (0x00007f702baf8000)
/lib64/ld-linux-x86-64.so.2 (0x00007f702c4fb000)
设置关联动态库配置文件
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf.d/openssl-1.1.1.conf
使配置文件生效
ldconfig -v
查看当前openssl版本
openssl version -a
备份openssl当前版本并关联新版本数据
mv /usr/bin/openssl /usr/bin/openssl.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
openssl version -a
