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
    /app/nfs   192.168.198.110(rw,all_squash,anonuid=991,anongid=986) 192.168.198.120(rw,all_squash,anonuid=991,anongid=986)

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
