Centos下yum方式安装nginx+PHP-FPM+eAccelerator+mysql

首先，添加安装源
Centos 默认官方源中没有nginx 和 php-fpm，所以必须添加第三方源，否则就只能自己编译了。

添加[CentALT]源
在/etc/yum.repo.d 目下创建 alt.ru.repo 文件内容如下：

	[CentALT]

	name=CentALT Packages for Enterprise Linux 5 - $basearch

	baseurl=http://centos.alt.ru/repository/centos/5/$basearch/

	enabled=1

	gpgcheck=0

启用 EPEL
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

32系统的用下面命令
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

安装 nginx +PHP-FPM +eAccelerator +mysql
yum update
yum install nginx php-fpm php-cli php-pdo php-mysql php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear php-pecl-memcache php-eaccelerator

配置优化Nginx
修改 /etc/nginx/nginx.conf,下面只列出修改的部分。
#根据CPU 核心processes，VPS下几个核心几个processes，独立服务器可x2

	worker_processes 4;

	#启用epoll

	worker_rlimit_nofile 51200;

	events {

	 worker_connections 51200;

	 use epoll;

	}

	#参数调整

	 sendfile on;

	 tcp_nopush on;

	 tcp_nodelay  on;

	 server_tokens off;

	 keepalive_timeout 50;

	 server_names_hash_bucket_size 128;

	 client_header_buffer_size 32k;

	 large_client_header_buffers 4 32k;

	 client_max_body_size 50m;

	#fastcgi优化

	 fastcgi_connect_timeout 300;

	 fastcgi_send_timeout 300;

	 fastcgi_read_timeout 300;

	 fastcgi_buffer_size64k;

	 fastcgi_buffers 4 64k;

	 fastcgi_busy_buffers_size 128k;

	 fastcgi_temp_file_write_size 256k;

	#开启gzip并优化

	 gzip on;

	 gzip_min_length 1k;

	 gzip_buffers 4 16k;

	 gzip_http_version 1.0;

	 gzip_comp_level 2;

	 gzip_types text/plain application/x-javascript text/css application/xml;

	 gzip_vary on;

php-fpm 调整

修改/etc/php-fpm.conf 将max_children 调为20
<value name="max_children">20</value>mysql 调整

修改/etc/my.conf [mysqld] 段加入如下指令

	skip-network

	skip-innodb

	skip-locking

	skip-bdb

	key_buffer  = 16K

	max_allowed_packet = 3M

	thread_stack = 64K

	thread_cache_size = 8

	table_cache  = 3

	query_cache_limit = 1M

	query_cache_size = 16M

系统内核调整

在/etc/sysctl.conf 加入

	net.ipv4.tcp_fin_timeout = 30

	net.ipv4.tcp_keepalive_time = 300

	net.ipv4.tcp_tw_reuse = 1

	net.ipv4.tcp_tw_recycle = 1

	net.ipv4.ip_local_port_range = 5000 65000

	net.ipv4.tcp_max_tw_buckets = 6000

	echo “ulimit -SHn 65535” >> /etc/rc.local

styctl -p 开启服务并设置系统启动默认启动

	ulimit -SHn 65535

	/etc/init.d/nginx start

	/etc/init.d/php-fpm start

	/etc/init.d/mysqld start

	chkconfig nginx on

	chkconfig php-fpm on

	chkconfig mysqld on
