知识图谱本体建模之RDF、RDFS、OWL详解（一）知识图谱本体建模之RDF、RDFS、OWL详解 1.语义网体系知识图谱于2012年由Google提出，并不是新概念，而是由语义网络(Semantic Network)衍生而来。语义网络由相互连接的节点和边组成，节点表示概念或者对象，边表示他们之间的关系。RDF，RDFS与OWL都是基于语义网的知识表示框架，在节点和边的取值上做了约束，制定了统一标准，为多源数据的融合提供了便利。RDF，RDFS/OWL 属于语义网技术栈，它们的提出，使得语义网克服了语义网络的缺点。其语义网技术栈如下所示。 2.RD 阅读详情

在linux centos6.5 中通过修改mysql的my.cnf配置文件来设置最大连接数，但是无论怎么改，mysql的连接数最多就是214个，再多了就不变了，但是通过 set global max_connections=1000则可以修改成功，不知道为什么，求教。

my.cnf内容如下：

[mysqld]

lower_case_table_names=1
character-set-server=utf8
max_connections=490
tmp_table_size = 268435456
max_heap_table_size =134217728
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
basedir =/data/mysql
datadir =/data/mysql/data
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION
