请问这样的是否正常？apache吃内存那么大

mysql的话，给大家一个好东西，也许很多人都用过
http://www.day32.com/MySQL/    找第一个script

或者直接http://www.day32.com/MySQL/tuning-primer.sh

他会给你提建议的

CODE:

-- MYSQL PERFORMANCE TUNING PRIMER --
             - By: Matthew Montgomery -

MySQL Version 5.0.41-log x86_64

Uptime = 2 days 13 hrs 24 min 23 sec
Avg. qps = 0
Total Questions = 80677
Threads Connected = 11

Server has been running for over 48hrs.
It should be safe to follow these recommendations

To find out more information on how each of these
runtime variables effects performance visit:
[url]http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html[/url]

SLOW QUERIES
Current long_query_time = 10 sec.
You have 0 out of 80695 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.

WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 1
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 768
Current threads_connected = 11
Historic max_used_connections = 13
The number of used connections is 1% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

MEMORY USAGE
Max Memory Ever Allocated : 217 M
Configured Max Per-thread Buffers : 7 G
Configured Max Global Buffers : 90 M
Configured Max Memory Limit : 7 G
Total System Memory : 3.96 G

Max memory limit exceeds 85% of total system memory

KEY BUFFER
Current MyISAM index space = 1 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 2571
Key buffer fill ratio = 3.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 64 M
Current query_cache_used = 6 M
Current query_cach_limit = 1 M
Current Query cache fill ratio = 9.84 %
Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 3 M
Current record/read_rnd_buffer_size = 508 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 4.00 M
You have had 0 queries where a join could not use an index properly
Your joins seem to be using indexes properly
join_buffer_size >= 4 M
This is not advised

OPEN FILES LIMIT
Current open_files_limit = 65535 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 32378 tables
You have a total of 230 tables
You have 278 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 256 M
Of 1092 temp tables, 37% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 28 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 57236
Your table locking seems to be fine

厄。。。。其实你如果系统资源不紧缺这玩意根本不必去管他

等待其他大大来研究，反正我的习惯就是12小时重启所有服务一次，其他不管。

其他的监控交给数据中心，出了downtime5分钟内他们会给我重启相关的 ...
