Nginx+PHP+memcache+MySQL實現快取伺服器
memcached快取應用
系統環境：
主機名 作業系統 ip地址 服務軟體
memcached centos7.5 192.168.80.102 memcached-1.5.9.tar.gz
libevent-2.1.8-stable.tar.gz
web1 centos7.5 192.168.80.103 安裝LNMP，memcache-2.2.7.tgz
客戶端 windows7 網頁瀏覽器
（在192.168.80.102上）
關閉防火牆及SElinux
systemctl stop firewalld
setenforce 0
memcached伺服器：
上傳原始碼包和外掛包：
yum install lrz* -y
memcached-1.5.9.tar.gz
libevent-2.1.8-stable.tar.gz
解壓
tar xf memcached-1.5.6.tar.gz -C /opt/
tar xf libevent-2.1.8-stable.tar.gz -C /opt/
yum install gcc gcc-c++ make -y
cd /opt/libevent-2.1.8-stable
./configure --prefix=/usr/local/libevent
make && make install
安裝memcached：
cd /opt/memcached-1.5.6
./configure
–prefix=/usr/local/memcached
–with-libevent=/usr/local/libevent/
make && make install
ln -s /usr/local/libevent/lib/libevent-2.1.so.6.0.2 /usr/lib64/libevent-2.1.so.6
//不可缺少
cd /usr/local/memcached/bin/
./memcached -d -m 32m -p 11211 -u root //以守護程序的方式分配32MB記憶體指定埠指定使用者賬號位root執行Memcached服務
設定Memcached 服務指令碼：
vi /etc/init.d/memcached
#!/bin/bash
#chkconfig: 35 99 20
#description: memcached Service Control Script
PROG="/usr/local/memcached/bin/memcached"
case “$1” in
start)
$PROG -d -m 32 -p 11211 -u root
;;
stop)
pkill -9 memcached &> /dev/null
;;
restart)
$0 stop
$0 start
;;
*)
echo “Usage: $0 {start|stop|restart|reload}”
exit 1
esac
exit 0
chmod +x /etc/init.d/memcached //新增執行許可權
chkconfig --add memcached //新增到service管理器
service memcached start //啟動
netstat -anpt | grep memcached
二、應用程式Memcache API（PHP伺服器）——在192.168.80.103上
安裝LNMP服務
1.安裝nginx
systemctl stop firewalld
yum -y install
pcre-devel
zlib-devel
lrz*
useradd -M -s /sbin/nologin nginx
tar xzvf nginx-1.13.7.tar.gz -C /opt/
cd /opt/nginx-1.13.7
./configure
–prefix=/usr/local/nginx
–user=nginx
–group=nginx
–with-http_stub_status_module
make && make install
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
nginx -t //配置檔案語法檢查
nginx //啟動服務
-------製作管理角本--------
vi /etc/init.d/nginx
#!/bin/bash
#chkconfig: 35 99 20
#description: Nginx Service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case “$1” in
start)
$PROG
;;
stop)
kill -s QUIT $(cat $PIDF)
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
;;
*)
echo “Usage: $0 {start|stop|restart|reload}”
exit 1
esac
exit 0
chmod +x /etc/init.d/nginx
chkconfig --add nginx
vi /usr/local/nginx/conf/nginx.conf
user nginx nginx;
error_log logs/error.log info;
2.安裝MySQL
yum -y install
ncurses
ncurses-devel
bison
cmake
useradd -s /sbin/nologin mysql
tar xf mysql-boost-5.7.20.tar.gz
cd mysql-5.7.20/
cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock

-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
-DMYSQL_DATADIR=/usr/local/mysql/data
-DWITH_BOOST=boost
-DWITH_SYSTEMD=1
make && make install
chown -R mysql.mysql /usr/local/mysql/ 也可mysql:mysql
vi /etc/my.cnf
[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock
[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock
[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
chown mysql:mysql /etc/my.cnf
echo ‘PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH’ >> /etc/profile
echo ‘export PATH’ >> /etc/profile
source /etc/profile
cd /usr/local/mysql/
bin/mysqld
–initialize-insecure
–user=mysql
–basedir=/usr/local/mysql
–datadir=/usr/local/mysql/data
cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld
netstat -anpt | grep 3306
systemctl enable mysqld
3.安裝PHP
yum -y install
libjpeg
libjpeg-devel
libpng libpng-devel
freetype freetype-devel
libxml2
libxml2-devel
zlib zlib-devel
curl curl-devel
openssl openssl-devel
tar xjvf php-7.1.10.tar.bz2
cd php-7.1.10
./configure
–prefix=/usr/local/php
–with-mysql-sock=/usr/local/mysql/mysql.sock
–with-mysqli
–with-zlib
–with-curl
–with-gd
–with-jpeg-dir
–with-png-dir
–with-freetype-dir
–with-openssl
–enable-mbstring
–enable-xml
–enable-session
–enable-ftp
–enable-pdo
–enable-tokenizer
–enable-zip
–enable-fpm
make && make install
cp php.ini-development /usr/local/php/lib/php.ini
vi /usr/local/php/lib/php.ini
mysqli.default_socket = /usr/local/mysql/mysql.sock
date.timezone = Asia/Shanghai
/usr/local/php/bin/php -m //驗證安裝的模組
-----------配置及優化FPM模組--------
cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf
cd /usr/local/php/etc/
vi php-fpm.conf
pid = run/php-fpm.pid
;user = nginx
;group = nginx
/usr/local/php/sbin/php-fpm -c /usr/local/php/etc/php.ini
netstat -anpt | grep 9000
ln -s /usr/local/php/bin/* /usr/local/bin/
ps aux | grep -c “php-fpm” //結果
-----更新啟動指令碼----------
vi /etc/init.d/nginx
#!/bin/bash
#chkconfig: 35 99 20
#description: Nginx Service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
PROG_FPM="/usr/local/php/sbin/php-fpm"
PIDF_FPM="/usr/local/php/var/run/php-fpm.pid"
case “$1” in
start)
$PROG
$PROG_FPM
;;
stop)
kill -s QUIT $(cat $PIDF)
kill -s QUIT $(cat $PIDF_FPM)
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
;;
*)
echo “Usage: $0 {start|stop|restart|reload}”
exit 1
esac
exit 0
--------以下是讓nginx支援PHP功能--------
vi /usr/local/nginx/conf/nginx.conf
location ~ .php$ {
root /var/www/aa;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/aa$fastcgi_script_name; //注意目錄名稱
include fastcgi_params;
}
vi /var/www/aa/index.php
<?php phpinfo(); ?>在網頁測試http://192.168.80.102/index.php，要注意路徑問題。
客戶端安裝Memcache的PHP擴充套件功能
#安裝autoconf軟體包
yum install autoconf -y
#解壓
tar xf memcache-2.2.7.tgz -C /opt/
#進入目錄
cd /opt/memcache-2.2.7
#增加為PHP的模組後再對memcache進行配置編譯
/usr/bin/phpize
#配置
./configure
–enable-memcache
–with-php-config=/usr/bin/php-config
#編譯及安裝
make && make install
22.編輯php.ini
vi /etc/php.ini
#732行，新增以下命令
extension_dir = “/usr/lib64/php/modules/”
#864行，新增以下命令
extension = memcache.so
23.編寫測試頁面，測試memcached工作是否正常
vi /var/www/aa/index.php
<?php $memcache = new Memcache(); $memcache->connect('192.168.80.102',11211); $memcache->set('key','Memcache test Successfull!',0,60); $result = $memcache->get('key'); unset($memcache); echo $result; ?>24.重啟httpd服務
service httpd restart
