Ubuntu24.04普通安装mysql

1、初始化mysql时报错

/opt/sudytech/mysql/bin/mysqld --initialize-insecure

/opt/sudytech/mysql/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

解决方法:

find  / -name libaio.so*
/usr/lib/x86_64-linux-gnu/libaio.so
/usr/lib/x86_64-linux-gnu/libaio.so.1t64
/usr/lib/x86_64-linux-gnu/libaio.so.1t64.0.2

cd /usr/lib/x86_64-linux-gnu/
ln -s   libaio.so.1t64.0.2 libaio.so.1

2、初始化完成后,登录报错

/opt/sudytech/mysql/bin/mysql -u root -p

/opt/sudytech/mysql/bin/mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

解决方法

#cd /usr/lib/x86_64-linux-gnu

#ll libncursesw.so.6*
lrwxrwxrwx 1 root root     18 Apr  8  2024 libncursesw.so.6 -> libncursesw.so.6.4
-rw-r--r-- 1 root root 239848 Apr  8  2024 libncursesw.so.6.4

#ln -s libncursesw.so.6.4 libncurses.so.5

3、第三次报错

/opt/sudytech/mysql/bin/mysql -u root -p

/opt/sudytech/mysql/bin/mysql: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

解决方法:

#ll libtinfo.so.6*
lrwxrwxrwx 1 root root     15 Apr  8  2024 libtinfo.so.6 -> libtinfo.so.6.4
-rw-r--r-- 1 root root 208328 Apr  8  2024 libtinfo.so.6.4

#ln -s libtinfo.so.6.4 libtinfo.so.5
