今天在登陆新安装好的数据库报如下错误：

 

  1. [root@lnmp ~]# mysql -uroot -p
  2. Enter password:
  3. Welcome to the MySQL monitor. Commands end with ; or \g.
  4. Your MySQL connection id is 13
  5. Server version: 8.0.21
  6.

  12.  
  13. 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

 

  1. [root@lnmp mysql-8.0.21]# find ./ -name terminal.c
  2. ./extra/libedit/libedit-20190324-3.1/src/terminal.c
  3.  

查找出来之后按照以下方式修改

 

 

  1. [root@lnmp mysql-8.0.21]# vim /opt/mysql-8.0.21/extra/libedit/libedit-20190324-3.1/src/terminal.c
  2. 842 terminal_set(EditLine *el, const char *term)
  3. 843 {
  4. 844 int i;
  5. 845 /*char buf[TC_BUFSIZE];*/
  6. 846 char *area;
  7. 847 const struct termcapstr *t;
  8. 848 sigset_t oset, nset;
  9. 849 int lins, cols;
  10. 850
  11. 851 (void) sigemptyset(&nset);
  12. 852 (void) sigaddset(&nset, SIGWINCH);
  13. 853 (void) sigprocmask(SIG_BLOCK, &nset, &oset);
  14. 854
  15. 855 area = NULL;

修改完之后在重新编译安装就可以了
