我已经在Centos 7，单服务器安装，内部存储配置上安装了mariadb-columnstore-1.2.2-1-centos7.x86_64。运行postConfigure脚本时没有遇到错误，并且列存储数据库也可以正常启动。
但是，当我取消注释/usr/local/mariadb/columnstore/mysql/my.cnf中的innodb参数并通过mcsadmin中的“ stopSystem”和“ startSystem”重新启动数据库时，服务器似乎无法启动尝试启动mysqld时失败。重新注释my.cnf中的innodb参数，然后启动服务器即可正常工作。以下是我从mcsadmin控制台看到的错误以及错误日志。有没有其他人经历过类似的经历？任何建议/见解将不胜感激！
* from the default my.cnf, the innodb parameters in question, uncommented that break the server startup:
# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend
innodb_log_group_home_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
innodb_log_arch_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 384M
innodb_additional_mem_pool_size = 20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 100M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

答案 0 :(得分：0)
我忘记检查了一条日志：
/usr/local/mariadb/columnstore/mysql/db/db-01.err
出现此错误：
2019-03-18 12:30:13 139826114562176 [ERROR] / usr / local / mariadb / columnstore / mysql // bin / mysqld：未知变量'innodb_additional_mem_pool_size = 20M'
不建议使用innodb_additional_mem_pool_size参数。
注释该参数可以解决问题。
