lnmp环境的优化
注意：修改配置文件，如果要修改pid进程文件相关，socket文件相关的参数的值时，一定要把服务stop掉
nginx的优化：
vi nginx.conf (最优配置)
#user nobody nobody;
worker_processes 8;
error_log logs/error.log;
pid logs/nginx.pid;
worker_rlimit_nofile 51200; （确保ulimit -n，打开文件数至少为51200）

use epoll;
worker_connections 51200;
}

php的优化：
vi /usr/local/php/etc/php-fpm.conf (最优配置)
[global]
pid = /usr/local/php/run/php-fpm.pid
error_log = /tmp/php-fpm.log
log_level = notice
emergency_restart_threshold = 10
emergency_restart_interval = 1m
process_control_timeout = 5s
daemonize = yes
rlimit_files = 65536
events.mechanism = epoll
[www]
user = nobody
group = nobody
listen = 127.0.0.1:9000
listen.owner = nobody
listen.group = nobody
listen.mode = 0666
listen.allowed_clients = 127.0.0.1
pm = static
pm.max_children =250
#pm.start_servers = 20
#pm.min_spare_servers = 10
#pm.max_spare_servers = 30
pm.max_requests = 10240
slowlog = /tmp/$pool.log.slow
request_slowlog_timeout = 600
request_terminate_timeout = 0
rlimit_files = 65536
catch_workers_output = yes
security.limit_extensions = .php .php3 .php4 .php5 .5p
注意：
pm = static参数：
对于专用服务器，pm可以设置为static。
如何控制子进程，选项有static和dynamic。如果选择static，则仅由pm.max_children参数指定固定的子进程数。如果选择dynamic，则由下列参数决定（每个进程（php-cgi）正常运行一段时间大概占用20M-30M,所以根据自己的内存计算，比如我分配给php的内存是4G）
pm.max_children = 200 #子进程最大数
pm.start_servers = 100 #启动时的进程数
pm.min_spare_servers = 50 #保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.max_spare_servers = 150 #保证空闲进程数最大值，如果空闲进程大于此值，则进行清理
mysql优化：
vi /usr/local/mysql/my.cnf （主要优化的是innodb）
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/mysql/data
port = 3306
server-id = 1
pid-file = /opt/mysql/data/mysql.pid
socket = /tmp/mysqld.sock
default_storage_engine = InnoDB
log-bin = /opt/mysql/binlog/mysql-binlog
expire_logs_days = 14
max_binlog_size = 5G
binlog_cache_size = 10M
max_binlog_cache_size = 20M
slow_query_log
long_query_time = 2
slow_query_log_file = /opt/mysql/data/slow.log
open_files_limit = 65535
innodb = FORCE
innodb_buffer_pool_size = 100M
innodb_log_file_size = 1G
query_cache_size = 0
thread_cache_size = 64
table_definition_cache = 512
table_open_cache = 512
max_connections = 20
sort_buffer_size = 10M
max_allowed_packet = 6M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[client]
#socket=/var/lib/mysql/mysql.sock
注意：
innodb_buffer_pool_size：主要作用是缓存innodb表的索引，数据，插入数据时的缓冲；
默认值：128M；
专用mysql服务器设置此值的大小： 系统内存的70%-80%最佳。
如果你的系统内存不大，查看这个参数，把它的值设置小一点吧（若值设置大了，启动会报错）
[mysqld]basedir = /usr/local/mysql
