一 打开my.cnf 文件 命令为： vi my.cnf
二 添加以下参数进去：
1> skip-external-locking
2> skip-name-resolve
3> big_tables
4> local_infile = 0
5> character-set-server=utf8
6>datadir=/usr/local/mysql/data/
7>basedir=usr/local/mysql/
8> table_cache=16
9> max_connections = 200
10> wait_timeout = 28800
11> interactive_timeout = 28800
12> thread_cache= 30
13> thread_concurrency= 2
14> tmpdir= /usr/local/mysql/tmp/
15> key_buffer = 16M
16> net_retry_count= 10
17> connect_timeout= 10
18> net_read_timeout= 30
19> query_cache_type= 0
20> query_cache_limit = 8MB
21> query_cache_min_res_unit = 4KB
22> query_cache_size = 56M
23> net_write_timeout= 30
24> group_concat_max_len = 999999999
25> interactive-timeout
26> bulk_insert_buffer_size = 2M
27> myisam_sort_buffer_size = 8M
28> read_rnd_buffer_size= 512K
29> join_buffer_size = 64M
30> max_heap_table_size= 20M
31> tmp_table_size= 20M
32> skip-slave-start
33>default-storage-engine = innodb
34> innodb_data_home_dir =
35>innodb_data_file_path=/usr/local/mysql/data/ibdata1:200M;/usr/local/mysql/data/ibdata2:200M:autoextend
36>innodb_log_group_home_dir = /usr/local/mysql/data/
37>innodb_buffer_pool_size=2056M
38>innodb_additional_mem_pool_size=16M
39>innodb_locks_unsafe_for_binlog=1
40>innodb_log_files_in_group = 2
41> innodb_log_file_size=256M
42> innodb_log_buffer_size=32M
43> innodb_flush_log_at_trx_commit=2
44> innodb_lock_wait_timeout=50
45> innodb_rollback_on_timeout
46> innodb_checksums=0
47> innodb_support_xa=0
48> innodb_doublewrite=0
49> innodb_thread_concurrency = 10
50>innodb_concurrency_tickets = 100
51> transaction-isolation = REPEATABLE-READ
二 需要修改的参数有：
1> sort_buffer_size = 16M
2> = 256M
3>write_buffer = 1M
4> server-id= 1016
5> = 2M
6> socket= /usr/local/mysql/tmp/mysql.sock
三 需要删除的参数有：
skip-locking
table_open_cache
binlog_format=mixed
net_buffer_length
