安装环境如下:
192.168.148.129   Memcache
192.168.148.130   php
192.168.148.131   nginx
192.168.148.136   MySQL
  • 安装nginx

下载nginx软件包

[root@bogon ~]#  useradd -M -s /sbin/nologin nginx
[root@bogon ~]#  yum -y install openssl-devel
[root@bogon ~]# tar zxf pcre-8.39.tar.gz -C /usr/src
[root@bogon ~]#  tar zxf zlib-1.2.8.tar.gz -C /usr/src
[root@bogon ~]#  tar zxf nginx-1.14.0.tar.gz -C /usr/src
[root@bogon ~]#  cd /usr/src/nginx-1.14.0/
[root@bogon  nginx-1.14.0]# ./configure --prefix=/usr/local/nginx \
--user=nginx --group=nginx --with-http_dav_module \
--with-http_stub_status_module --with-http_addition_module \
--with-http_sub_module --with-http_flv_module --with-http_mp4_module \
--with-pcre=/usr/src/pcre-8.39 --with-zlib=/usr/src/zlib-1.2.8 \
--with-http_ssl_module --with-http_gzip_static_module && make && make install
[root@bogon ~]#  ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin
[root@bogon ~]#  nginx
[root@bogon ~]#  netstat -anpt | grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      8460/nginx: master  

下载php软件包

[root@localhost ~]# yum -y install libxml2-devel lzip2-devel libcurl-devel  libmcrypt-devel openssl-devel bzip2-devel 
[root@localhost ~]# tar zxf libmcrypt-2.5.7.tar.gz 
[root@localhost ~]# cd libmcrypt-2.5.7/
[root@localhost libmcrypt-2.5.7]# ./configure --prefix=/usr/local/libmcrypt && make && make install
[root@localhost ~]# tar zxf php-5.6.27.tar.gz 
[root@localhost ~]# cd php-5.6.27/
[root@localhost php-5.6.27]# ./configure --prefix=/usr/local/php5.6 --with-mysql=mysqlnd \
--with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-openssl --enable-fpm --enable-sockets \
--enable-sysvshm --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib \
--with-libxml-dir=/usr --enable-xml --with-mhash --with-mcrypt=/usr/local/libmcrypt  \
--with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d \
--with-bz2 --enable-maintainer-zts && make && make install
[root@localhost php-5.6.27]# cp php.ini-production /etc/php.ini
[root@localhost php-5.6.27]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.6.27]# chmod +x /etc/init.d/php-fpm 
[root@localhost php-5.6.27]# chkconfig --add php-fpm
[root@localhost php-5.6.27]# chkconfig php-fpm on
[root@localhost php-5.6.27]# cp /usr/local/php5.6/etc/php-fpm.conf.default /usr/local/php5.6/etc/php-fpm.conf
[root@localhost php-5.6.27]# vim /usr/local/php5.6/etc/php-fpm.conf
修改内容如下: 
pid = run/php-fpm.pid 
listen = 192.168.31.141:9000    \\本地ip地址(千万不能用127.0.0.1)
pm.max_children = 50 
pm.start_servers = 5 
pm.min_spare_servers = 5 
pm.max_spare_servers = 35 
[root@localhost php-5.6.27]# service php-fpm start
Starting php-fpm  done
[root@localhost php-5.6.27]# netstat -anpt | grep php-fpm
tcp        0      0 192.168.148.130:9000    0.0.0.0:*               LISTEN      130988/php-fpm: mas 
  • 安装MySQL数据库

下载mysql脚本一键安装

[root@bogon ~]# mysql -u root -p123
mysql> create database testdb1;
mysql> use testdb1;
mysql> grant all on *.* to xws@'192.168.148.%' identified by '123456';
mysql> create table test1(id int not null auto_increment,name varchar(20) default null,primary  key (id)) engine=innodb auto_increment=1 default charset=utf8;
mysql> insert into test1(name) values ('tom1'),('tom2'),('tom3'),('tom4'),('tom5');
mysql> select * from test1;
+----+------+
| id | name |
+----+------+
|  1 | tom1 |
|  2 | tom2 |
|  3 | tom3 |
|  4 | tom4 |
|  5 | tom5 |
+----+------+
5 rows in set (0.00 sec)
nginx操作如下:
[root@bogon nginx-1.14.0]# vim /usr/local/nginx/conf/nginx.conf  //修改如下(大约在43行)

        location / {
            root   html;
            index  index.php index.html index.htm;
        }
          location ~ \.php$ {
            root           /var/www/html;
            fastcgi_pass   192.168.148.130:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi.conf;
        }
[root@bogon nginx-1.14.0]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@bogon nginx-1.14.0]# nginx -s reload

php操作如下:

[root@bogon ~]# mkdir -p /var/www/html
[root@bogon ~]# vim /var/www/html/test.php

[root@bogon ~]# vim /var/www/html/test1.php

怎么搭建Memcache服务

  • 安装Memecache

下载memcache

[root@bogon ~]# tar zxf libevent-2.0.22-stable.tar.gz -C /usr/src/
[root@bogon ~]# cd /usr/src/libevent-2.0.22-stable/

[root@bogon ~]# netstat -anpt | grep 11211
  • php操作如下(安装Memecache客户端)
[root@bogon ~]# tar zxf memcache-3.0.8.tgz -C /usr/src/
[root@bogon ~]# cd /usr/src/memcache-3.0.8/
[root@bogon memcache-3.0.8]# /usr/local/php5.6/bin/phpize

//在PHP主配置文件中填写memcache.so模块存放的路径
[root@PHP ~]# systemctl restart php-fpm

客户端访问如下:

怎么搭建Memcache服务

在PHP服务器上安装telnet工具测试

[root@PHP ~]# yum -y install telnet
[root@PHP ~]# telnet 192.168.148.129 11211           //登陆到memcached的11211端口
Trying 192.168.148.129...
Connected to 192.168.148.129.
Escape character is '^]'.
get key              //查询ID为“key”的键值对,可以看到我们测试脚本写入的“test=123”
VALUE key 1 66
O:8:"stdClass":2:{s:8:"str_attr";s:4:"test";s:8:"int_attr";i:123;}
END
//在进行上面的get验证时,需要将test2.php文件中插入的键值对的保存时间值改大一些
//或者重新访问一下,以免缓存失效,查询不到
quit                     //退出当前环境
Connection closed by foreign host.
[root@PHP ~]# 
测试Memcache缓存数据库
[root@PHP ~]# vim /var/www/html/test4.php 
connect($memcachehost,$memcacheport) or die ("Could not connect");
$query="select * from test1 limit 10";
$key=md5($query);
if(!$memcache->get($key))
{
$conn=mysql_connect("192.168.1.8","lzj","123456");                        //指定数据库服务器的IP地址、用户及密码
mysql_select_db(testdb1);
$result=mysql_query($query);
while ($row=mysql_fetch_assoc($result))
{
$arr[]=$row;
}
$f = 'mysql';
$memcache->add($key,serialize($arr),0,30);
$data = $arr ;
}
else{
$f = 'memcache';
$data_mem=$memcache->get($key);
$data = unserialize($data_mem);
}
echo $f;
echo "
