Percona XtraDB Cluster是针对MySQL用户的高可用性和扩展性解决方案,基于Percona Server 。其包括了Write Set REPlication补丁,使用Galera 2.0库,这是一个针对事务性应用程序的同步多主机复制插件。

Percona XtraDB Cluster特点:

  (1)同步复制,事务在所有集群节点要么同时提交,要么不提交。

  (2)多主复制,可以在任意一个节点写入。

  (3)从服务器上的并行应用事件,真正的“并行复制”。

  (4)自动配置节点。

  (5)数据一致性,没有不同步的从服务器。

实验系统:CentOS 6.6_x86_64

实验前提:防火墙和selinux都关闭,服务器上没有安装任何版本的MYSQL

实验说明:本实验共有3台主机,IP分配如拓扑

实验拓扑:

Percona XtraDB Cluster集群的安装与配置

一、安装percona环境

  1.配置yum源:

yum -y install
yum -y epel*

  2.安装Percona软件:

yum -y install Percona-XtraDB-Cluster-server Percona-XtraDB-Cluster-client Percona-Server-shared-compat percona-xtrabackup

  3.添加账户:

/etc/init.d/mysql bootstrap-pxc    //启动PXC
mysql
---------------------------------------->
GRANT RELOAD,LOCK TABLES,REPLICATION CLIENT ON *.* TO com@localhost IDENTIFIED BY '123456';
FLUSH PRIVILEGES;
\q
/etc/init.d/mysql stop

二、编辑PXC的节点配置:

  1.在19.66上:

vim /etc/my.cnf
------------------------------------->
wsrep_provider=/usr/lib64/libgalera_smm.so
wsrep_cluster_address="gcomm://192.168.19.66,192.168.19.74,192.168.19.76"
wsrep_sst_auth=com:123456
wsrep_cluster_name=Percona
wsrep_sst_method=xtrabackup-v2
wsrep_node_address=192.168.19.66
wsrep_slave_threads=2
innodb_locks_unsafe_for_binlog=1
innodb_autoinc_lock_mode=2
/etc/init.d/mysql bootstrap-pxc

  2.在19.74上:

vim /etc/my.cnf
-------------------------------------->
wsrep_provider=/usr/lib64/libgalera_smm.so
wsrep_cluster_address="gcomm://192.168.19.66,192.168.19.74,192.168.19.76"
wsrep_sst_auth=com:123456
wsrep_cluster_name=Percona
wsrep_sst_method=xtrabackup-v2
wsrep_node_address=192.168.19.74
wsrep_slave_threads=2
innodb_locks_unsafe_for_binlog=1
innodb_autoinc_lock_mode=2
/etc/init.d/mysql start

  3.在19.76上:

vim /etc/my.cnf
-------------------------------->
wsrep_provider=/usr/lib64/libgalera_smm.so
wsrep_cluster_address="gcomm://192.168.19.66,192.168.19.74,192.168.19.76"
wsrep_sst_auth=com:123456
wsrep_node_address=192.168.19.76
wsrep_cluster_name=Percona
wsrep_sst_method=xtrabackup-v2
wsrep_slave_threads=2
innodb_locks_unsafe_for_binlog=1
innodb_autoinc_lock_mode=2
/etc/init.d/mysql start

  4.各节点上查看状态,保证如下几项没有问题:

mysql
---------------------------------------------->
SHOW STATUS LIKE '%wsrep%';
+------------------------------+----------------------------------------------------------+
| Variable_name                | Value                                                    |
+------------------------------+----------------------------------------------------------+
| wsrep_local_state_uuid      | a82bc530-3748-11e5-a4fc-c26f7c90839c                    |
...
| wsrep_local_state            | 4                                                        |
| wsrep_local_state_comment    | Synced                                                  |
...
| wsrep_cluster_size          | 3                                                        |
| wsrep_cluster_status        | Primary                                                  |
| wsrep_connected              | ON                                                      |
...
| wsrep_ready                  | ON                                                      |
+------------------------------+----------------------------------------------------------+

  5.测试:

    在19.66上:

CREATE DATABASE jason;
USE jason;
CREATE TABLE jjj (id int ,name char(10)) engine=innodb;
COMMIT;

    在19.74上:

USE jason;
INSERT INTO jjj values (1,'22');
COMMIT;

    在19.76上:

USE jason;
SELECT * FROM jjj;

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
