NFS 192.168.198.131
[root@danran app]# mkdir nfs
[root@danran app]# ls
nfs
[root@danran app]# chmod o+w nfs/
[root@danran app]# useradd -r nfsuser -s /sbin/nologin
[root@danran app]# vim /etc/exports \将/app/nfs目录共享给192.168.198.110和192.168.198.120两台web服务器

web1和web2 192.168.198.110/120挂载NFS目录
[root@danran html]# vim /etc/fstab
192.168.198.131:/app/nfs /var/www/html nfs defaults 0 0
[root@danran html]# mount -a
在NFS服务器192.168.198.131的/app/nfs共享目录安装wordpress
tar xvf wordpress-4.8-zh_CN.tar.gz
mv wordpress /app/nfs/blog
cd /app/nfs/blog
setfacl -m u:nfsuser:rwx blog/ \因为所有远程用户都映射为了nfsuser，故授予nfsuserrwx权限
或
chmod o+w blog
setfacl -m u:daemon:rwx blog/
或
cp wp-config-sample.php wp-config.php
vim wp-config.php
define('DB_NAME', 'nfsdb');
define('DB_USER', 'nfs');
define('DB_PASSWORD', 'danran');
define('DB_HOST', '192.168.198.130');
两台web服务器上编译安装xcache
下载xcache-3.2.0.tar.bz2
tar xf xcache-3.2.0.tar.bz2
cd xcache-3.2.0
/app/php/bin/phpize 生成编译环境.configure脚本
./configure --enable-xcache --with-php-config=/app/php/bin/php-config
make && make install
注意最后结果的一行目录
ls /app/php/lib/php/extensions/no-debug-non-zts-20131226/xcache.so
mkdir /etc/php.d/
cp xcache.ini /etc/php.d/
vim /etc/php.d/xcache.ini
[xcache-common]
修改
extension = /app/php/lib/php/extensions/no-debug-non-zts-20131226/xcache.so
service httpd restart
