Make required directory and create soft link.

1 [root@docker mysql]# mkdir -p /data/mysql/mysql3306/{data,logs,tmp}
2 [root@docker mysql]# ln -sv /opt/mysql/mysql-8.0.11-linux-glibc2.12-x86_64 /usr/local/mysql
3 ‘/usr/local/mysql’ -> ‘/opt/mysql/mysql-8.0.11-linux-glibc2.12-x86_64’

 

Create mysql group & user.

1 [root@docker mysql]# userdel mysql
2 [root@docker mysql]# groupadd mysql
3 [root@docker mysql]# useradd -g mysql -s /sbin/nologin -d /usr/local/mysql -MN mysql

 

Modify directory privilege.

1 [root@docker mysql]# cd /usr/local
2 [root@docker local]# chown -R mysql.mysql mysql

 

Modify environment variable.

1 [root@docker local]# echo "export PATH=$PATH:/usr/local/mysql/bin" >> ~/.bash_profile
2 [root@docker local]# source ~/.bash_profile
3 [root@docker local]# echo $PATH
4 /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin

 

Prepare a suitable my.cnf in docker and then copy it to specific path.

1 [root@docker local]# cp /opt/mysql/my.cnf /data/mysql/mysql3306/my3306.cnf

 

Initialize MySQL db.

[root@docker local]# mysqld --defaults-file=/data/mysql/mysql3306/my3306.cnf --initialize

It still has problem 'cause size of "./ibdata1" is incompatible with the parameter in "my3306.cnf".

1 [root@docker data]# ls -l ibdata1

After I started mysqld several seconds later,the process down again at once.

*The error shows that the value is not equal between "lower_case_table_names" and dictionary.*

1 [root@docker data]# cat /opt/mysql/my.cnf|grep lower_case_table_names
2 lower_case_table_names              =1                              #    0

After I've modified my3306.cnf,it seems no error occurs now.

Summary

  • ldd can be used to check if mysqld is missing "libxxx.so" file.Then you can install or copy directly into "/usr/lib64" directory.
  • There're many errors in my installation procedure due to inappropriate parameters.
  • Because of the vagrant,all the shared directories in docker contains also has the 777 privilege what cause the world-writable issue.
  • Since MySQL 5.7,password of root@localhost must be changed while first login.Otherwise,you can do nothing at all.
