Mysql install on Gentoo

I've tried to install Mysql with emerge but without success. That's why, I install it manually by following the install file in the binary distribution :

  • shell> groupadd mysql
  • shell> useradd -r -g mysql mysql
  • shell> cd /usr/local
  • shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
  • shell> ln -s full-path-to-mysql-VERSION-OS mysql
  • shell> cd mysql
  • shell> chown -R mysql .
  • shell> chgrp -R mysql .
  • shell> scripts/mysql_install_db --user=mysql
I have the following error :

Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

To solve this issue , I install libaio with emerge dev-libs/libaio

  • shell> chown -R root .
  • shell> chown -R mysql data
  • shell> cp support-files/my-medium.cnf /etc/my.cnf
  • shell> bin/mysqld_safe --user=mysql &
In the file monfichier.err which is located in  /usr/local/mysql/data/ I have the following error : Can't open and lock privilege tables: Table 'mysql.user' doesn't exist

I solve the problem with mysql_install_db --user=mysql --ldata=/usr/local/mysql/data/


Note :

I have the same error with :
GRANT ALL ON tbl.* TO 'user'@'localhost' IDENTIFIED BY 'tbl';
==> Error Mysql.User doesn't exist

In fact, I have an old version of Mysql on my computer. So, I unstall it and I type the following :

./scripts/mysql_install_db --user=mysql --ldata=/usr/local/mysql/data/
