项目测试mysql数据导入功能，所以自己搭建数据库服务器，测试产品功能。在安装导入的过程中遇到了大量问题，最终一一解决，在自己记录下自己解决问题的过程，可供参考。
一、mysql安装之后启动失败，通过查看/var/log/mysqld.log日志文件报如下错误：
2018-10-17T04:29:31.727009Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.12) starting as process 1654
2018-10-17T04:29:31.738339Z 1 [ERROR] [MY-012592] [InnoDB] InnoDB: Operating system error number 13 in a file operation.
2018-10-17T04:29:31.738373Z 1 [ERROR] [MY-012595] [InnoDB] InnoDB: The error means mysqld does not have the access rights to the directory.
2018-10-17T04:29:31.738386Z 1 [ERROR] [MY-012270] [InnoDB] InnoDB: os_file_get_status() failed on './ibdata1'. Can't determine file permissions
2018-10-17T04:29:31.738406Z 1 [ERROR] [MY-010334] [Server] Failed to initialize DD Storage Engine
2018-10-17T04:29:31.738524Z 0 [ERROR] [MY-010020] [Server] Data Dictionary initialization failed.
2018-10-17T04:29:31.738549Z 0 [ERROR] [MY-010119] [Server] Aborting
查看数据库data目录权限：
/var/lib # ls -Z mysql
-rw-rw----. mysql mysql unconfined_u:object_r:var_lib_t:s0 ibdata1
drwx--x--x. mysql mysql unconfined_u:object_r:var_lib_t:s0 mysql
drwx------. mysql mysql unconfined_u:object_r:var_lib_t:s0 performance_schema
-rw-r--r--. root root unconfined_u:object_r:var_lib_t:s0 RPM_UPGRADE_HISTORY
-rw-r--r--. mysql mysql unconfined_u:object_r:var_lib_t:s0 RPM_UPGRADE_MARKER-LAST
drwxr-xr-x. mysql mysql unconfined_u:object_r:var_lib_t:s0 test
需要修改目录权限解决
chcon -R -t mysqld_db_t mysql
问题原因是selinux的权限控制问题，更改下就可以了。
二、导入csv文件一直报错：
导入数据的时候，报如上错误！发现从本地导入文件的参数没有打开；
mysql> SHOW VARIABLES LIKE '%local%';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | OFF |
+---------------+-------+
1 row in set (0.00 sec)开启该参数，因为是全局参数，所以需要加上global；
SET GLOBAL local_infile=1再次导入数据，导入成功！
load data local infile '/opt/data-set/1_train_19_Run_or_walk_information.csv' into table `test`.`19_normal` character set utf8 fields terminated by ',' enclosed by '"' lines terminated by '\r\n';
另外注意LINES TERMINATED BY '\r\n'，在linux上需要用'\r\n',windows上使用'\n'
