#mysqld --initialize-insecure --user=mysql --basedir=/app/local/mysql --datadir=/app/mysql/data --pid-file=/app/mysql/mysql.pid

$installDir/bin/mysqld --initialize-insecure --user=mysql --basedir=/app/local/mysql --datadir=/app/mysql/data

以上脚本安装完成：
#systemctl start mysqld
注意事项:
1.定义数据库安装目录，数据存放目录

2. my.cnf文件要注意，建议用我提供的，后期再调优。如果不是我的my.cnf可以在执行$installDir/bin/mysqld 这条命令时可以创建库文件，但启动mysqld时日志提示pid文件不存在导致无法启动数据库。
3. 可能报错
