修改php.ini文件
手工修改：查找/usr/local/webapp/php/etc/php.ini中的
extension_dir = "./"
修改为
extension_dir = "/usr/local/webapp/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 = "imagick.so"
extension = "memcache.so"
extension = "memcached.so"
extension = "oci8.so"
再查找output_buffering = Off 修改为output_buffering = On
配置eAccelerator加速PHP：
mkdir -p /usr/local/webapp/eaccelerator_cache
vi /usr/local/webapp/php/etc/php.ini
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension="/usr/local/webapp/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/usr/local/webapp/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="300"
eaccelerator.shm_prune_period="120"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
/usr/sbin/groupadd -M www -s /sbin/nologin

安装nginx
tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/
./configure
make && make install
cd ../
tar zxvf nginx-0.8.29.tar.gz
cd nginx-0.8.29/
./configure --user=www --group=www --prefix=/usr/local/webapp/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../
创建nginx配置文件
在/usr/local/webapp/nginx/conf/目录中创建fcgi.conf文件：
输入
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
编辑nginx.conf设置解析php
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
配置nginx.conf
服务加入开机自启动
ulimit -SHn 51200
/usr/local/webapp/php/sbin/php-fpm start
/usr/local/webapp/nginx/sbin/nginx
vi /usr/local/webapp/nginx/html/test.php
<?php
phpinfo();
?>
查看各种信息
系统优化
