--with-http_flv_module \

--with-http_gzip_static_module \

--with-http_stub_status_module \

--with-http_realip_module \

--with-pcre

make&&make install

2）启动nginx服务

cd /usr/local/services

ln -sf nginx-1.6.3 nginx

sudo ./nginx/sbin/nginx

sudo netstat -antlp|grep 80

tcp        0     0 0.0.0.0:80       0.0.0.0:*     LISTEN      4690/nginx

cat status.conf 

server {

    listen       80;

    server_name  127.0.0.1;

    auth_basic "kibana Access";

    auth_basic_user_file /usr/local/services/nginx/conf/users;

    location /nginxstatus {

        stub_status on;

        allow 127.0.0.1;

        deny all;

    }

    location ~/phpstatus {

        include fastcgi_params;

        fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;

        fastcgi_pass 127.0.0.1:9000;

        allow 127.0.0.1;

        deny all;

    }

     ssl on;
    ssl_certificate     /etc/nginx/ssl/xxxxx.crt;
    ssl_certificate_key /etc/nginx/ssl/xxxxx.key;

}

printf "${USERNAME}:`openssl passwd -crypt ${PASSWD}`\n"

log_format main "$http_x_forwarded_for | $time_local | $request | $status | $body_bytes_sent | "
                "$request_body | $content_length | $http_referer | $http_user_agent | $nuid | "
                "$http_cookie | $remote_addr | $hostname | $upstream_addr |"             
                "$upstream_response_time | $request_time";

http1.0和http1.1的最大区别是前者不支持HTTP Keep-Alive

nginx反向代理HTTP协议时，默认使用的是http1.0去后端服务器获取响应内容，在返回客户端。

而nginx再向后端服务器请求时使用了http1.0同时使用HTTP Header的Connection:Close控制后端服务器主动关闭连接，这就导致一个客户端的请求都在后端服务器上产生一个TIME_WAIT状态的连接。

修改nginx协议使用http1.1同时支持keep-alive,必须要增三个参数：如下

...

upstream web1{

    keepalive 50;#必须设置，建议值50-100

    server ...;

}

...

location / {

    proxy_http_version 1.1; #后端配置支持http1.1，必须

    proxy_set header Connection "";#后端配置支持http1.1，必须

...

}

2、mysql的安装

1）、编译安装

sudo groupadd mysql

sudo useradd -s /sbin/nologin -g mysql mysql

sudo yum -y install ncurses-devel  gcc gcc-c++   bison cmake

tar zxf mysql-5.5.41.tar.gz

cd mysql-5.5.41

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/services/mysql5.5.41 \

-DMYSQL_DATADIR=/usr/local/services/mysql5.5.41/var/data \

-DMYSQL_UNIX_ADDR=/usr/local/services/mysql5.5.41/var/data/mysql.sock \

-DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DEXTRA_CHARSETS=all -DWITH_DEBUG=0 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 

make&&make install

2）创建编译时所用目录，及常用命令链接

cd /usr/local/services/

ln -sf mysql5.5.41 mysql 

cd mysql

sudo chown -R mysql.mysql ./*

sudo mkdir -p /data/tsp/mysql

ln -s /data/tsp/mysql var

sudo mkdir -p /usr/local/services/mysql/var/{binlog,data,logs,redolog,relaylog}

sudo ln -sf /usr/local/services/mysql/bin/mysql /usr/local/bin/

sudo ln -sf /usr/local/services/mysql/bin/mysqldump /usr/local/bin/

sudo ln -sf /usr/local/services/mysql/bin/mysqlbinlog /usr/local/bin/

sudo ln -sf /usr/local/services/mysql/bin/mysqladmin /usr/local/bin/

sudo ln -sf /usr/local/services/mysql/include/ /usr/include/mysql

sudo chown -R mysql.mysql /usr/local/services/mysql/var

3）初始化

sudo vim /etc/ld.so.conf.d/mysql-x86_64.conf

/usr/local/services/mysql/lib

sudo  ldconfig -v

sudo scripts/mysql_install_db --user=mysql --datadir=/usr/local/services/mysql/var/data --basedir=/usr/local/services/mysql

PS：(5.7.7+初始化)

sudo bin/mysqld --user=mysql --datadir=/usr/local/services/mysql/var/data --basedir=/usr/local/services/mysql  --initialize 

如果配置了my.cnf的log_error，那么初始密码在log_error文件中，否则会打印出来。

mysql.user 的authentication_string等同于5.6以前mysql.user的password字段

4）服务开机启动，获取配置文件

cd support-files/

sudo cp mysql.server /etc/init.d/mysqld

sudo chmod +x /etc/init.d/mysqld 

sudo chkconfig --add mysqld

sudo chkconfig  mysqld on

sudo cp my-medium.cnf my.cnf

1最安全的，但性能页是最差的。如果对数据一致性和完整性要求不高，完全可以设为2,如果只最求性能，例如高并发写的日志服务器，设为0来获得更高性能

*/

6）启动mysql

sudo service mysqld start

Starting MySQL.                                            [  OK  ]

3、安装PHP的扩展插件

1)、安装libiconv
对文本进行编码间的转换，用它来处理中文各种编码之间的转换

tar zxf libiconv-1.14.tar.gz

cd libiconv-1.14

./configure --prefix=/usr/local/services/libiconv-1.14

make&& make install

2）、安装libmcrypt 实现加密功能的库

==============

2）、配置

cd /usr/local/services/

ln -sf php-5.5.30 php

cd php/etc

cp php-fpm.conf.default php-fpm.conf

sudo groupadd www

sudo useradd -g www www

vim  php-fpm.conf

[global]

pid=run/php-fpm.pid

error_log=log/php-fpm.log

log_level=error

daemonize=yes

[www]

user=www

group=www

listen=127.0.0.1:9000

#listen = /usr/local/services/php/var/php/php-fpm.sock

pm=dynamic

pm.max_children=32

pm.start_servers=15

pm.min_spare_servers=5

pm.max_spare_servers=32

pm.status_path = /phpstatus

3)、启动PHP服务

cd php-5.5.30/sapi/fpm

sudo cp init.d.php-fpm /etc/init.d/php-fpm

sudo chmod +x /etc/init.d/php-fpm

sudo  chkconfig --add php-fpm

sudo  chkconfig php-fpm on

/etc/init.d/php-fpm start

ps -ef|grep php

4)、编辑nginx

vim /usr/local/services/nginx/conf/nginx.conf

location / {

            root   html;

            index  index.php  index.html index.htm;

        }

location ~ \.php$ {

            root           html;

            fastcgi_pass   127.0.0.1:9000;

            #fastcgi_pass  /usr/local/services/php/var/php/php-fpm.sock;

            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

            include        fastcgi_params;

        }

5）、编译fastcgi_params

加入一行fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

vim /usr/local/services/nginx/conf/fastcgi_params

5、重启服务，进行测试

sudo /usr/local/services/nginx/sbin/nginx -s reload

/etc/init.d/php-fpm restart

vim /usr/local/services/nginx/html/index.php

<?php

phpinfo();

?>

测试数据库链接正常否

vim /usr/local/services/nginx/html/linkdb.php

<?php

$links=mysql_connect("localhost","root","");

if($links){

        echo "link db ok!";

}

else{

        echo "link db no!";

}

?>

6、memcached安装

1）、

tar xf libevent-1.4.14b-stable.tar.gz

cd libevent-1.4.14b-stable

./configure --prefix=/usr/local/services/libs/libevent-1.4.14b

make

make install

cd /usr/local/services/libs/

test ! -h /usr/local/services/libs/libevent && ln -s libevent-1.4.14b libevent

tar xf memcached-1.4.24.tar.gz

cd memcached-1.4.24

./configure --prefix=/usr/local/services/memcached-1.4.24 --with-libevent=/usr/local/services/libs/libevent

make

make install

启动memcached

/memcached  -l "192.168.9.87" -p 11211 -d -m 256 -c 65536 

2）、

使用php自带的pecl安装程序
# /usr/local/services/php/bin/pecl install memcache

vim /usr/local/services/php/etc/php.ini 增加两行

extension_dir = "/usr/local/servers/php5/lib/php/extensions/no-debug-non-zts-20060922/"

extension="memcache.so"

=========================

也可以从源码安装
cd memcached-1.4.24
/usr/local/servers/php/bin/phpize
 ./configure --enable-memcache=/usr/local/servers/memcached --with-php-config=/usr/local/servers/php/bin/php-config 
make && make inst

=========================

sudo /etc/init.d/php-fpm restart

验证 vim /usr/local/services/nginx/html/test.php

<?php

$memcache = new Memcache;

$memcache->connect('192.168.10.35', 11211) or die ("Could not connect");

$version = $memcache->getVersion();

echo "Server's version: ".$version."<br/>\n";

$tmp_object = new stdClass;

$tmp_object->str_attr = 'test';

$tmp_object->int_attr = 123;

$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");

echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

$get_result = $memcache->get('key');

echo "Data from the cache:<br/>\n";

var_dump($get_result);

?>

显示结果：

Server's version: 1.4.24
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
object(stdClass)#3 (2) {  ["str_attr"]=>  string(4) "test"  ["int_attr"]=>  int(123) } 

7、部署discuz

discuz防止路径为：/usr/local/services/bbs

vim nginx.conf

        location ^~ /bbs/ {

        root /usr/local/services;

        fastcgi_split_path_info ^(.+\.php)(.*)$;

        if ( $fastcgi_script_name ~ \..*\/.*php ) { 

        return 403;

         }   

        include fastcgi_params;

        fastcgi_index index.php;

        fastcgi_param PATH_INFO $fastcgi_path_info;

        if ( $fastcgi_script_name ~ .*\.php($|/) ) { 

            fastcgi_pass 127.0.0.1:9000;

        add_header Cache-Control "no-store, no-cache, must-revalidate,  pre-check=0, post-check=0, max-age=0";

        add_header Pragma no-cache;

        }   

    }  

访问http://ip/bbs/install

根据提示就行设置

至此论坛就部署OK啦

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;#脚本文件请求的路径 

eg:/data/www/bbs/index.php 

fastcgi_param  QUERY_STRING       $query_string; #请求的参数;如?app=123  

fastcgi_param  REQUEST_METHOD     $request_method; #请求的动作(GET,POST)  

fastcgi_param  CONTENT_TYPE       $content_type; #请求头中的Content-Type字段  

fastcgi_param  CONTENT_LENGTH     $content_length; #请求头中的Content-length字段。

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name; #脚本名称

eg：index.php

fastcgi_param  REQUEST_URI        $request_uri; #请求的地址不带参数  

fastcgi_param  DOCUMENT_URI       $document_uri; #与$uri相同。   

fastcgi_param  DOCUMENT_ROOT      $document_root; #网站的根目录。在server配置中root指令中指定的值   

eg:/data/www/bbs

fastcgi_param  SERVER_PROTOCOL    $server_protocol; #请求使用的协议，通常是HTTP/1.0或HTTP/1.1。    

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;#cgi 版本  

fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;#nginx 版本号，可修改、隐藏 

fastcgi_param  REMOTE_ADDR        $remote_addr; #客户端IP  

fastcgi_param  REMOTE_PORT        $remote_port; #客户端端口  

fastcgi_param  SERVER_ADDR        $server_addr; #服务器IP地址  

fastcgi_param  SERVER_PORT        $server_port; #服务器端口  

fastcgi_param  SERVER_NAME        $server_name; #服务器名，域名在server配置中指定的server_name   

#fastcgi_param  PATH_INFO           $path_info;#可自定义变量  

 

在php可打印出上面的服务环境变量  

如：echo $_SERVER['REMOTE_ADDR']
