mysql部分
rpm -e --nodeps mariadb-libs groupadd -r mysql useradd -r -g mysql -s /bin/false -M mysql tar zxf mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz mv mysql-8.0.11-linux-glibc2.12-x86_64 /usr/local/mysql mkdir /usr/local/mysql/data chown -R mysql:mysql /usr/local/mysql/ ln -s /usr/local/mysql/bin/* /usr/local/bin cat >> /etc/my.cnf << EOF [client] socket=/usr/local/mysql/data/mysql.sock [mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql/data port=3306 pid-file=/usr/local/mysql/data/mysql.pid server_id=1 socket=/usr/local/mysql/data/mysql.sock log-error=/usr/local/mysql/data/mysql.err EOF mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld chkconfig on mysqld systemctl daemon-reload systemctl start mysqld
memcache部分
tar zxf libevent-2.0.22-stable.tar.gz cd libevent-2.0.22-stable/ ./configure && make&& make install tar zxf memcached-1.4.33.tar.gz cd memcached-1.4.33/ ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local make && make install
vi ~/.bash_profile
MEMCACHED_HOME=/usr/local/memcached LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$MEMCACHED_HOME/lib
memcached -d -m 2048 -l 192.168.154.131 -p 11211 -u root -c 10240 -P /usr/local/memcached/memcached.pid firewall-cmd --permanent --add-port=11211/tcp firewall-cmd --reload
在 php 上
加载memcache.so（使php作为memcache的客户端）
tar zxf memcache-3.0.8.tgz cd memcache-3.0.8/ /usr/local/php/bin/phpize ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config make && make install
注意：安装完后会有类似这样的提示： Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/；记住这个路径，需要加载到php的配置文件中。
vim /etc/php.ini
##查找extension并在对应位置添加 extension=/usr/local/php/lib/php/extensions/no-debug-zts-20131226/memcache.so ##在末尾添加 session.save_handler = memcache session.save_path = "tcp://192.168.154.131:11211?persistent=1&weight=1&timeout=1&retry_interval=15"
service php-fpm restart
在nginx上
编写php测试页面。vim /usr/local/nginx/html/index.php
<?php phpinfo(); ?>
访问 http://192.168.154.132 ，应当可以看到memcache和session字样。
（成功表示php上安装好了memcache.so）
编写memcache测试页面。vim /usr/local/nginx/html/test.php
<?php
$memcache = new Memcache;
$memcache->connect('192.168.154.131', 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Server's version: ".$version."
";
$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)
";
$get_result = $memcache->get('key');
echo "Data from the cache:
";
var_dump($get_result);
?>
预计会输出四行字符，有memcache版本信息等
（成功表示连接到了memcache服务器）
编写测试memcache的session共享脚本，vim /usr/local/nginx/html/session.php
<?php
session_start();
if (!isset($_SESSION['session_time']))
{
$_SESSION['session_time'] = time();
}
echo "now_time:".time()."
";
echo "session_id:".session_id()."
";
?>
预计输出session_time、now_time、session_id
使用telnet连接memcache
telnet 192.168.154.131 11211
然后get session_id的值，如果得到的session_time和网页上的一样表示session共享成功。
在 mysql 上
mysql> create database testdb1;
mysql> use testdb1;
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)
mysql> grant select on testdb1.* to user@'%' identified by '123456';
在nginx上
编辑memcache缓存mysql测试页面，vim /usr/local/nginx/html/test_db.php
<?php
$memcachehost = '192.168.154.131';
$memcacheport = 11211;
$memcachelife = 60;
$memcache = new Memcache;
$memcache->connect($memcachehost,$memcacheport) or die ("Could not connect");
$query="select * from test1 limit 10";
$key=md5($query);
if(!$memcache->get($key))
{
$conn=mysql_connect("192.168.154.134","user","123456");
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 $f;
echo "<br>"
echo "$key";
echo "<br>"
//print_r($data);
foreach($data as $a)
{
echo "number is <b><font color=#FF0000>$a[id]</font></b>";
echo "<br>";
echo "name is <b><font color=#FF0000>$a[name]</font></b>";
echo "<br>";
}
?>
预计会输出memcache的key，和我们在mysql创建的数据表的数据
（成功即表示memcache缓存到mysql的数据）
