linux安装mysql8遇到的坑

root@bigdata-159:/usr/local/mysql# ./bin/mysqld – defaults-file=/etc/my.cnf --initialize --user=mysql
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决方法：
yum install -y libaio //安装后在初始化就OK了

输入mysql -u root -p出现错误：-bash: mysql: command not found
解决方法：
输入 alias mysql=/usr/local/mysql/bin/mysql 后 再输入mysql -u root -p 即可
