mysql8登陆数据库报错Segmentation fault (核心已转储)的解决办法

1821

今天在登陆新安装好的数据库报如下错误：

[root@lnmp ~]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 13
Server version: 8.0.21

Segmentation fault (核心已转储)

原因好像是和C语言有关系

解决办法：

修改terminal.c文件重新编译安装

[root@lnmp mysql-8.0.21]# find ./ -name terminal.c
./extra/libedit/libedit-20190324-3.1/src/terminal.c

查找出来之后按照以下方式修改

[root@lnmp mysql-8.0.21]# vim /opt/mysql-8.0.21/extra/libedit/libedit-20190324-3.1/src/terminal.c
 842 terminal_set(EditLine *el, const char *term)
 843 {
 844         int i;
 845         /*char buf[TC_BUFSIZE];*/
 846         char *area;
 847         const struct termcapstr *t;
 848         sigset_t oset, nset;
 849         int lins, cols;
 850 
 851         (void) sigemptyset(&nset);
 852         (void) sigaddset(&nset, SIGWINCH);
 853         (void) sigprocmask(SIG_BLOCK, &nset, &oset);
 854 
 855         area = NULL;
