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) [root@danran app]# systemctl restart nfs [root@danran app]# systemctl restart rpcbind [root@danran app]# firewall-cmd --add-service=nfs --permanent [root@danran app]# firewall-cmd --add-service=rpc-bind --permanent [root@danran app]# firewall-cmd --reload [root@danran app]# setenfore 0 [root@danran app]# iptables -F

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/blogsetfacl -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.somkdir /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.soservice httpd restart
