/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../


安装Zend Optimizer,32位系统版本

tar zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz
mkdir -p /usr/local/zend/
cp ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /usr/local/zend/

如果是64位系统,则

tar zxvf ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz
mkdir -p /usr/local/zend/
cp ZendOptimizer-3.3.9-linux-glibc23-x86_64/data/5_2_x_comp/ZendOptimizer.so /usr/local/zend/


配置php.ini

cat >>/usr/local/php/etc/php.ini< [Zend Optimizer]
zend_optimizer.optimization_level=1
zend_extension="/usr/local/zend/ZendOptimizer.so"
EOF

7,修改php.ini文件
手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"

再查找 output_buffering = Off
修改为output_buffering = On

自动修改:可执行以下shell命令,自动完成对php.ini文件的修改:

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\n#' /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini


8,配置eAccelerator加速PHP:
创建缓存目录

mkdir -p /usr/local/eaccelerator_cache

配置php.ini

cat >>/usr/local/php/etc/php.ini< [eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="1"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys = "disk_only"
eaccelerator.sessions = "disk_only"
eaccelerator.content = "disk_only"
EOF


9,创建www用户和组,以及主机需要的目录,日志目录

groupadd www
useradd -g www www
mkdir -p /home/www
chmod +w /home/www
mkdir -p /home/www/logs
chmod 777 /home/www/logs
chown -R www:www /home/www


10,创建php-fpm配置文件

rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf

输入以下内容,我设置开的进程是5个.需要更改进程数,可以修改5

< ?xml version="1.0" ?>

All relative paths in this config are relative to php's install prefix

11,启动php-cgi进程,监听127.0.0.1的9000端口,进程数为5,用户为www

ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start

注:/usr/local/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload

12,安装Nginx

tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/
./configure
make && make install
cd ../

tar zxvf nginx-0.7.65.tar.gz
cd nginx-0.7.65/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
make && make install
cd ../


13,创建Nginx配置文件

mkdir -p /usr/local/nginx/conf/servers
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf

输入以下内容:

user www www;
worker_processes 1;
error_log /home/www/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
#charse gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 128k;
large_client_header_buffers 4 256k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;

fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 9;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
output_buffers 4 32k;
postpone_output 1460;

#limit_zone crawler $binary_remote_addr 10m;

server
{
listen 80;
server_name vps.imcat.in;
index index.html index.htm index.php;
include location.conf;
root /home/www;
}
include servers/*;
}

14,在/usr/local/nginx/conf/目录中创建location.conf文件：

vi /usr/local/nginx/conf/location.conf

输入内容:

location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}

location ~ .*\.(js|css)?$
{
expires 12h;
}

多站点管理,可以在/usr/local/nginx/conf/servers目录添加配置文件,格式为:

vi /usr/local/nginx/conf/servers/yourwebsite.conf

内容:

server

{
listen 80;
server_name yourdomain;
index index.html index.htm index.php;
root /home/www/yourwebsite;
}

请注意,我是没有开启Nginx日志记录功能的.
启动Nginx:

ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

放个探针看看

mv index.php /home/www/

访问你的IP看看吧!

15,安装phpMyAdmin,管理Mysql数据库

tar zxvf phpMyAdmin-3.2.4-all-languages.tar.gz
mv phpMyAdmin-3.2.4-all-languages /home/www/phpmyadmin


16,配置开机自动启动Nginx + PHP

echo "ulimit -SHn 65535" >>/etc/rc.local
echo "/usr/local/php/sbin/php-fpm start" >>/etc/rc.local
echo "/usr/local/nginx/sbin/nginx" >>/etc/rc.local


17,优化Linux内核参数(我只在Xen VPS用过,Openvz VPS失败,慎用,可不操作。)

vi /etc/sysctl.conf

在最后加入

# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535

使配置立即生效：

/sbin/sysctl -p


18,需要安装ftp的,可以简单安装vsftpd应用:

yum -y install vsftpd
/etc/init.d/vsftpd start
chkconfig --level 345 vsftpd on


19,请务必更改www用户密码:

passwd www


zt from imcat.in
