libssl.so.1.1: cannot open shared object file

使用 Ubuntu 22.04 時，有時候會遇到如下錯誤

error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

這是因為Ubuntu 22.04 默認使用的是 openssl3.0 ，但是大多為 Ubuntu 生成的可執行文件依賴 openssl 1.1

安裝Openssl 1.1

我們可以采取源碼安裝的方式解決這個問題

下載源碼包并解壓

首先確定已經安裝下載工具

apt install -y wget 

隨后執行下載操作

wget https://www.openssl.org/source/openssl-1.1.1q.tar.gz

對下載的文件解壓并進入到文件夾中

tar xvf openssl-1.1.1q.tar.gz && cd openssl-1.1.1q

安裝 GCC、Perl、Make

首先確保 Ubuntu 22.04 已經安裝 GCC Perl Make工具
如果你不知道這幾樣是什么，那么請執行安裝命令

sudo apt install -y perl gcc make

執行 config 配置

在成功安裝上述工具后執行 config命令

./config

如果一切正常應出現下方提示:

Operating system: x86_64-whatever-linux2
Configuring OpenSSL version 1.1.1q (0x1010111fL) for linux-x86_64
Using os-specific seed configuration

編譯

隨后執行 make

make 

等待編譯成功后將出現類似如下提示：

${LDCMD:-gcc} -pthread -m64 -Wa,--noexecstack -Wall -O3 -L.   \
        -o test/x509_dup_cert_test test/x509_dup_cert_test.o \
         test/libtestutil.a -lcrypto -ldl -pthread

         test/libtestutil.a -lcrypto -ldl -pthread
make[1]: Leaving directory '/root/openssl-1.1.1q'

安裝

這時 openssl1.1 就已經編譯好了，我們還需要將動態庫放入 /usr/local/lib中，執行 make install 即可

sudo make install 

執行成功后將出現類似以下提示:

設置環境變量并生效

有些可執行文件讀取的動態鏈接庫的路徑不同，這里最好設置一下動態鏈接庫的環境變量

sudo echo "export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/lib" >> /etc/profile

執行 source /etc/profile 使其在當前客戶端生效

source /etc/profile

這樣就成功解決了這個問題
