在Centos7中安裝mysql 5.7.19，得到權限錯誤

我想在與/ usr/local/mysql不同的地方安裝mysql。運行命令'sudo bin/mysqld --defaults-file =/home/hadoop/app/mysql-5.7.19 -linux-glibc2.12-x86_64/my.cnf --initialize --user = mysql'時，得到以下錯誤：在Centos7中安裝mysql 5.7.19，得到權限錯誤

您正在運行MySQL守護程序爲MySQL用戶（--user=mysql）。但是，您正在給它提供一個存在於hadoop用戶主目錄中的路徑。 mysql用戶無權訪問hadoop主目錄。

mysql用戶應該有，read, write, execute許可

chown -R mysql.mysql /home/hadoop/app/mysql-5.7.19-linux-glibc2.12-x86_64/

如果你想通過2用戶使用，那麼使用setfacl

setfacl -R -m u:mysql:rwx -m u:some_other_user:rw /home/hadoop/app/mysql-5.7.19-linux-glibc2.12-x86_64/

，如果你想給目錄然後代替:u使用:g
