mysql 启动报错 libicuuc.so.71找不到

error while loading shared libraries: libicuuc.so.71:

  1. [wbw@wbw-majaro lib]$ /usr/bin/mysqld $MYSQLD_OPTS
  2. /usr/bin/mysqld: error while loading shared libraries: libicuuc.so.71: cannot open shared object file: No such file or directory

ldd /usr/bin/mysqld 查看缺少那些lib.so

解决方法

1. 下载libicuuc 71版本

官网地址：http://site.icu-project.org/home
GitHub下地址：https://github.com/unicode-org/icu/releases/tag/release-71-1

2. 安装libicuuc

我的电脑是manjaro Linux 我直接下载了GitHub的 icu4c-71_1-Fedora32-x64.tgz版本，解压里面存在对应的 libicuuc.so.71文件，于是我直接将 libicuuc.so.71复制到我的lib目录

  1. wbw@wbw-majaro lib]$ sudo cp  /home/wbw/下载/icu/usr/local/lib/libicui.so.71 /usr/lib
  2. libicui18n.so       libicui18n.so.71    libicui18n.so.71.1  libicuio.so         libicuio.so.71      libicuio.so.71.1    
  3. [wbw@wbw-majaro lib]$ sudo cp  /home/wbw/下载/icu/usr/local/lib/libicui18n.so.71 /usr/lib
  4. [wbw@wbw-majaro lib]$ /usr/bin/mysqld $MYSQLD_OPTS
  5. /usr/bin/mysqld: error while loading shared libraries: libicudata.so.71: cannot open shared object file: No such file or directory
  6. [wbw@wbw-majaro lib]$ sudo cp  /home/wbw/下载/icu/usr/local/lib/libicudata.so.71 /usr/lib
复制完成后，再次启动mysql

启动成功
