环境
    my.cnf中[client]需要配置使用的用户,执行show status/variables权限，可以给super
        user = myadmin

  1. -- MYSQL PERFORMANCE TUNING PRIMER --
  2. - By: Matthew Montgomery -
  4. MySQL Version 5.5.19-log x86_64
  6. Uptime = 23 days 3 hrs 17 min 8 sec
  7. Avg. qps = 2
  8. Total Questions = 4543819
  9. Threads Connected = 10
  11. Server has been running for over 48hrs.
  12. It should be safe to follow these recommendations
  14. To find out more information on how each of these
  15. runtime variables effects performance visit:
  16. http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html
  17. Visit http://www.mysql.com/products/enterprise/advisors.html
  18. for info about MySQL\'s Enterprise Monitoring and Advisory Service
  20. SLOW QUERIES
  21. The slow query log is NOT enabled.
  22. Current long_query_time = 10.000000 sec.
  23. You have 21 out of 4543840 that take longer than 10.000000 sec. to complete
  24. Your long_query_time seems to be fine
  26. BINARY UPDATE LOG
  27. The binary update log is enabled
  28. The expire_logs_days is not set.
  29. The mysqld will retain the entire binary log until RESET MASTER or PURGE MASTER LOGS commands are run manually
  30. Setting expire_logs_days will allow you to remove old binary logs automatically
  31. See http://dev.mysql.com/doc/refman/5.5/en/purge-master-logs.html
  32. Binlog sync is not enabled, you could loose binlog records during a server crash
  34. WORKER THREADS
  35. Current thread_cache_size = 0
  36. Current threads_cached = 0
  37. Current threads_per_sec = 1
  38. Historic threads_per_sec = 0
  39. Your thread_cache_size is fine
  41. MAX CONNECTIONS
  42. Current max_connections = 151
  43. Current threads_connected = 10
  44. Historic max_used_connections = 152
  45. The number of used connections is 100% of the configured maximum.
  46. You should raise max_connections
  48. INNODB STATUS
  49. Current InnoDB index space = 0 bytes
  50. Current InnoDB data space = 0 bytes
  51. Current InnoDB buffer pool free = 0 %
  52. Current innodb_buffer_pool_size = 128 M
  53. Depending on how much space your innodb indexes take up it may be safe
  54. to increase this value to up to 2 / 3 of total system memory
  56. MEMORY USAGE
  57. Max Memory Ever Allocated : 411 M
  58. Configured Max Per-thread Buffers : 250 M
  59. Configured Max Global Buffers : 160 M
  60. Configured Max Memory Limit : 410 M
  61. Physical Memory : 3.73 G
  62. Max memory limit seem to be within acceptable norms
  64. KEY BUFFER
  65. Current MyISAM index space = 9 K
  66. Current key_buffer_size = 16 M
  67. Key cache miss rate is 1 : 659
  68. Key buffer free ratio = 81 %
  69. Your key_buffer_size seems to be fine
  71. QUERY CACHE
  72. Query cache is supported but not enabled
  73. Perhaps you should set the query_cache_size
  75. SORT OPERATIONS
  76. Current sort_buffer_size = 512 K
  77. Current read_rnd_buffer_size = 512 K
  78. Sort buffer seems to be fine
  80. JOINS
  81. Current join_buffer_size = 132.00 K
  82. You have had 398 queries where a join could not use an index properly
  83. You should enable \"log-queries-not-using-indexes\"
  84. Then look for non indexed joins in the slow query log.
  85. If you are unable to optimize your queries you may want to increase your
  86. join_buffer_size to accommodate larger joins in one pass.
  88. Note! This script will still suggest raising the join_buffer_size when
  89. ANY joins not using indexes are found.
  91. OPEN FILES LIMIT
  92. Current open_files_limit = 60000 files
  93. The open_files_limit should typically be set to at least 2x-3x
  94. that of table_cache if you have heavy MyISAM usage.
  95. Your open_files_limit value seems to be fine
  97. TABLE CACHE
  98. Current table_open_cache = 64 tables
  99. Current table_definition_cache = 400 tables
  100. You have a total of 0 tables
  101. You have 64 open tables.
  102. Current table_cache hit rate is 0%
  103. , while 100% of your table cache is in use
  104. You should probably increase your table_cache
  106. TEMP TABLES
  107. Current max_heap_table_size = 16 M
  108. Current tmp_table_size = 16 M
  109. Of 303828 temp tables, 1% were created on disk
  110. Created disk tmp tables ratio seems fine
  112. TABLE SCANS
  113. Current read_buffer_size = 256 K
  114. Current table scan ratio = 60 : 1
  115. read_buffer_size seems to be fine
  117. TABLE LOCKING
  118. Current Lock Wait ratio = 1 : 12920
  119. Your table locking seems to be fine
