解决mysql8.0.18报Segmentation fault错的问题

报错如下：

     显示完下面信息之后，就显示：

owners.

Segmentation fault (core dumped)

 

解决办法：

1、通过命令 locate terminal.c查找到我们的这个文件

[root@localhost mysql-8.0.18]# locate terminal.c
/opt/mysql-8.0.18/extra/libedit/terminal.c
/opt/mysql-8.0.18/extra/libedit/CMakeFiles/edit.dir/terminal.c.o

2、修改文件/opt/mysql-8.0.18/extra/libedit/terminal.c，将 area = buf;改为 area = NULL;

3、重新再编译的目录下重新make和make install

4、最后重启mysql

[root@localhost mysql-8.0.18]# mysql -uroot -hlocalhost -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
