安裝Memcache

Memcache的搭建需要借助于LAMP或LNMP，本篇博文采用LNMP結(jié)構(gòu)

安裝環(huán)境如下：

192.168.148.129   Memcache
192.168.148.130   php
192.168.148.131   nginx
192.168.148.136   MySQL

• 安裝nginx

下載nginx軟件包

[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

• 安裝PHP服務(wù)器

下載php軟件包

[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 php-5.6.27]# vim /usr/local/php5.6/etc/php-fpm.conf
修改內(nèi)容如下： 
pid = run/php-fpm.pid 
listen = 192.168.31.141:9000    \\本地ip地址（千萬不能用127.0.0.1）
pm.max_children = 50

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

• 安裝MySQL數(shù)據(jù)庫(kù)

下載mysql腳本一鍵安裝

mysql> use testdb1;
mysql> grant all on *.* to xws@'192.168.148.%' identified by '123456';
