************************ Large Pages Information *******************
Per process system memlock (soft) limit = 64 KB
Total Shared Global Region in Large Pages = 0 KB (0%)
Large Pages used by this instance: 0 (0 KB)
Large Pages unused system wide = 0 (0 KB)
Large Pages configured system wide = 0 (0 KB)
Large Page size = 2048 KB
RECOMMENDATION:--->推荐设置
Total System Global Area size is 1026 MB. For optimal performance,
prior to the next instance restart:
1. Increase the number of unused large pages by
at least 513 (page size 2048 KB, total size 1026 MB) system wide to
get 100% of the System Global Area allocated with large pages
2. Large pages are automatically locked into physical memory.
Increase the per process memlock (soft) limit to at least 1034 MB to lock
100% System Global Area's large pages into physical memory

掌握添加MySQL用户的方法对于数据库管理员和开发者至关重要,因为它确保数据库的安全性和访问控制。1)使用CREATEUSER命令创建新用户,2)通过GRANT命令分配权限,3)使用FLUSHPRIVILEGES确保权限生效,4)定期审计和清理用户账户以维护性能和安全。

在MySQL中处理字符串数据类型和索引的最佳实践包括:1)选择合适的字符串类型,如CHAR用于固定长度,VARCHAR用于可变长度,TEXT用于大文本;2)谨慎索引,避免过度索引,针对常用查询创建索引;3)使用前缀索引和全文索引优化长字符串搜索;4)定期监控和优化索引,保持索引小巧高效。通过这些方法,可以在读取和写入性能之间取得平衡,提升数据库效率。
