解决

问题，就是编译安装好后，输入mysql 报-bash: mysql: command not found
原因没有添加变量

[root@db01 scripts]# vim /etc/profile.d/mysql.sh
export PATH="/opt/mysql/bin:$PATH"
#加载环境变量
[root@db01 scripts]# source /etc/profile
#查看所有的环境变量
[root@db01 scripts]# echo $PATH
/opt/mysql/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

#检查端口
[root@db01 scripts]# netstat -lntup        
tcp6       0      0 :::3306                 :::*                    LISTEN      34209/mysqld

原因：
没有安装依赖libaio-deve
yum install -y libaio-deve 即可

1.回到 cd mysql-5.6.44
2.然后把rm -rf  CMakeCache.txt
3.cmake . -DCMAKE_INSTALL_PREFIX=/opt/mysql-5.6.44 -DMYSQL_DATADIR=/opt/mysql-5.6.44/data -DMYSQL_UNIX_ADDR=/opt/mysql-5.6.44/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_ZLIB=bundled -DWITH_SSL=bundled -DENABLED_LOCAL_INFILE=1 -DWITH_EMBEDDED_SERVER=1 -DENABLE_DOWNLOADS=1 -DWITH_DEBUG=0
