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
