傷城~ 2023-02-24 14:24 20阅读 0赞

**一、环境**

centos7，openssl-1.1.1g.tar.gz

**二、安装步骤**

1、下载最新版本：

[https://mirrors.cloud.tencent.com/openssl/source/][https_mirrors.cloud.tencent.com_openssl_source]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x1b3Fpbmdsb25nODUwMTAy_size_16_color_FFFFFF_t_70][]

2、检测系统版本

[root@sit-104 ~]# openssl versioin

3、开始安装

yum remove openssl #删除旧的

配置

./config --prefix=/usr/local/openssl

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x1b3Fpbmdsb25nODUwMTAy_size_16_color_FFFFFF_t_70 1][]

./config -t

make && make install

**三、问题**

1、openssl version提示错误，动态库找不到，如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x1b3Fpbmdsb25nODUwMTAy_size_16_color_FFFFFF_t_70 2][]

方法：建立软连接

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

动态库正常，如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x1b3Fpbmdsb25nODUwMTAy_size_16_color_FFFFFF_t_70 3][]

2、openssl version 提示找不到命令

因为新的ssl路径配置没生效，需要重新配置下

ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
     
    ln -s /usr/local/openssl/include/openssl /usr/include/openssl
     
    echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
     
    ldconfig -v

测试成功，如下图：
