MySQL and Apache Optimization

Hey guys my load is always going hight when I have 200 users browsing my phpBB forum. but its fine when I have 170 users online.

I have done many kind of mysql optimization and yet the load still wont go any down. when I have 170 users online the load is 1-2 but as soon as it hits 200 it becomes huge

Server Spec
p4 3.2 ghz
2Gb ram
300gb HDD

here is TOP


And heres whats inside my.cnf

Code:
[mysqld]
datadir=/var/lib/mysql
safe-show-database
old_passwords
back_log = 15
skip-innodb
max_connections = 200
key_buffer = 256M
myisam_sort_buffer_size = 128M
join_buffer_size = 1M
read_buffer_size = 16M
sort_buffer_size = 32M
table_cache = 2048
thread_cache_size = 784
wait_timeout = 15
connect_timeout = 10
tmp_table_size = 64M
max_heap_table_size = 64M
max_allowed_packet = 8M
max_connect_errors = 10
read_rnd_buffer_size = 524288
bulk_insert_buffer_size = 8M
query_cache_limit = 2M
query_cache_size = 712M
query_cache_type = 1
query_prealloc_size = 163840
query_alloc_block_size = 32768
default-storage-engine = MyISAM

[mysql.server]
user=mysql
basedir=/var/lib

[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/lib/mysql/mysql.pid
open_files_limit = 8192

[mysqldump]
quick
max_allowed_packet = 16M

[myisamchk]
key_buffer = 64M
sort_buffer = 64M
read_buffer = 16M
write_buffer = 16M

[mysqlhotcopy]
interactive-timeout


This is what inside my httpd.cnf

Code:
ServerType standalone
ServerRoot "/etc/httpd"
LockFile /var/run/httpd.lock
PidFile /var/run/httpd.pid
ScoreBoardFile logs/apache_runtime_status
ResourceConfig /dev/null
AccessConfig /dev/null

KeepAlive On
MaxKeepAliveRequests 300
KeepAliveTimeout 5
MinSpareServers 5
MaxSpareServers 20
StartServers 8
MaxClients 300

RE: MySQL and Apache Optimization

I think it's more related to poorly written queries. What are you hosting on the server that's consuming so much MySQL?

Please post output of the following commands:

Code:
ps aux | grep -c mysql
ps aux | grep -c httpd
free -m


Try the following optimizations, but it may or may not help much.

Code:
[mysqld]
datadir=/var/lib/mysql
safe-show-database
old_passwords
skip-innodb
max_connections = 200
key_buffer = 196M
myisam_sort_buffer_size = 32M
join_buffer_size = 2M
read_buffer_size = 2M
sort_buffer_size = 2M
table_cache = 2048
thread_cache_size = 50
interactive_timeout = 50
wait_timeout = 50
connect_timeout = 10
tmp_table_size = 64M
max_heap_table_size = 64M
max_connect_errors = 10
read_rnd_buffer_size = 4M
query_cache_limit = 2M
query_cache_size = 712M
query_cache_type = 0
default-storage-engine = MyISAM


Also, try optimizing your databases with:

Code:
mysqlcheck -uda_admin -p -ro --all-databases

RE: MySQL and Apache Optimization

Ok, please try the my.cnf file I provided above and restart your mysql server. Also, which kernel version are you using? (uname -a).

The following changes in httpd.conf will also help:

Code:
Timeout 30
KeepAlive On
MaxKeepAliveRequests 200
KeepAliveTimeout 4
MinSpareServers 15
MaxSpareServers 40
StartServers 15
MaxClients 300
MaxRequestsPerChild 1000


Good Luck!
