所以我正在配置mysql来运行多个实例。
当我尝试初始化datadir时，我收到此错误。
# mysql_install_db --user=mysql -- datadir=/var/lib/mysql/mysql1
[WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
[ERROR] The data directory '/var/lib/mysql/mysql1' already exist and is not empty.
# mysql_install_db --user=mysql -- datadir=/var/lib/mysql/mysql2
[WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
[WARNING] The bootstrap log isn't empty:
