                                                                这个标题有点浪费资源。由于本人常用LAMP架构,有因金山逍遥网张大师在nginx方面比较猛,决定小试一下。
四步走,将LAMP架构逐步过渡到nigx上。
这个测试web系统使用的是debian,所有包一般是apt-get
LAMP架构就不多说了。
原有系统跑有cacti,所以lamp架构没有问题。
第一步:安装
apt-get install nginx
vi /etc/nginx/sites-enabled/default
先修改端口80到其他端口,以免和现有apache冲突。
启动一次 /etc/init.d/nginx start
lynx http://ip:81 看看新web工作是否ok。
第二步配置php-fastcgi
apt-get install php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-json php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl
vi /etc/php5/cgi/php.ini
增加
       
       
       
       
        cgi.fix_pathinfo = 1
创建 php-fastcgi启动脚本
apt-get install php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-json php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl
cgi.fix_pathinfo = 1
内容全文如下,注意蓝色代码为一行.

        start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON

case "$1" in

        echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
        exit 3
        ;;
esac
chmod 755 /etc/init.d/php-fastcgi
再创建一个php-fastcgi控制参数的文件
vi /etc/default/php-fastcgi
#
# Settings for php-cgi in external FASTCGI Mode
#
# Should php-fastcgi run automatically on startup? (default: no)
START=yes
# Which user runs PHP? (default: www-data)
EXEC_AS_USER=www-data
# Host and TCP port for FASTCGI-Listener (default: localhost:9000)
FCGI_HOST=localhost
FCGI_PORT=9000
# Environment variables, which are processed by PHP
PHP_FCGI_CHILDREN=5
PHP_FCGI_MAX_REQUESTS=1000
/etc/init.d/php-fastcgi start
第三步:
vi /etc/nginx/sites-enabled/default
注意红色字体
       
       
       
        # You may add here your
# server {
#    ...
# }
# statements for each of your virtual hosts
server {
    listen   81;
    server_name  localhost;
    access_log  /var/log/nginx/localhost.access.log;
    location / {
        root   /var/www/;        index  index.php index.html index.htm;
    }
    location /doc {
        root   /usr/share;
        autoindex on;
        allow 127.0.0.1;
        deny all;
    }
    location /images {
        root   /usr/share;
        autoindex on;
    }
    #error_page  404  /404.html;
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/nginx-default;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
        #proxy_pass   http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {    fastcgi_pass   127.0.0.1:9000;    fastcgi_index  index.php;    fastcgi_param  SCRIPT_FILENAME  /var/www/$fastcgi_script_name;    include fastcgi_params;    }
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
        #deny  all;
    #}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#listen   8000;
#listen   somename:8080;
#server_name  somename  alias  another.alias;
#location / {
#root   html;
#index  index.html index.htm;
#}
#}
# HTTPS server
#
#server {
#listen   443;
#server_name  localhost;
#ssl  on;
#ssl_certificate  cert.pem;
#ssl_certificate_key  cert.key;
#ssl_session_timeout  5m;
#ssl_protocols  SSLv2 SSLv3 TLSv1;
#ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
#ssl_prefer_server_ciphers   on;
#location / {
#root   html;
#index  index.html index.htm;
#}
#}
第四步:测试
vi /var/www/testphp.php
vi /var/www/testsql.php
chmod 755 *.php
chown www-data:www-data *.php
lynx http://ip:81/test.php
lynx http://ip:81/testsql.php
作为过渡的话,现在我还需要干掉apache,将nginx的web端口修改为80,测试cacti工作ok,测试phpmysql工作ok。
tips:当出现No input file specified时,注意查看virtualhost
fastcgi_param SCRIPT_FILENAME /var/virtalhost/html$fastcgi_script_name
