使用ubantu安裝mysql時，出現報錯

[email protected]:/home/soft/mysql-5.6.41-linux-glibc2.12-x86_64# ./scripts/mysql_install_db --user=mysql --datadir=/home/soft/mysql-5.6.41-linux-glibc2.12-x86_64/mysqldata/mysql
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
 

原因是未安裝libaio，負責非同步IO。

安裝libaio1

下列軟體包有未滿足的依賴關係：
 mysql-community-server : 依賴: mysql-common (>= 5.6.40-1ubuntu14.04) 但是它將不會被安裝
                          依賴: mysql-client (= 5.6.40-1ubuntu14.04) 但是它將不會被安裝
E: 有未能滿足的依賴關係。請嘗試不指明軟體包的名字來執行“apt-get -f install”(也可以指定一個解決辦法)。

安裝完畢後啟動mysqld
