单机部署PXC,部署pxc

在一台机器上安装PXC Linux:centos 7     IP:192.168.30.221
PXC版本:Percona-XtraDB-Cluster-5.7.17-rel13-29.20.3.Linux.x86_64.ssl101.tar.gz
PXC节点:①192.168.30.221:3306     cluster_address:4030                
②192.168.30.221:3307     cluster_address:5030                
③192.168.30.221:3308     cluster_address:6030   yum -y install rsync
wget 
  1、将二进制包解压,添加mysql账号,做软连接: mkdir /opt/mysql cd
/opt/mysql tar zxvf
/data/src/Percona-XtraDB-Cluster-5.7.17-rel13-29.20.3.Linux.x86_64.ssl101.tar.gz
cd /usr/local ln
-s /opt/mysql/Percona-XtraDB-Cluster-5.7.17-rel13-29.20.3.Linux.x86_64.ssl101/
mysql groupadd mysql useradd -M -g mysql -s /sbin/nologin/ -d
/usr/local/mysql mysql   2、新建文件夹请授权: mkdir -p
/data/mysql/mysql_3306/{data,logs,tmp} mkdir -p
/data/mysql/mysql_3306/logs/binlog mkdir -p
/data/mysql/mysql_3307/{data,logs,tmp} mkdir -p
/data/mysql/mysql_3307/logs/binlog mkdir -p
/data/mysql/mysql_3308/{data,logs,tmp} mkdir -p
/data/mysql/mysql_3308/logs/binlog chown -R mysql:mysql /data/mysql/
chown -R mysql:mysql /usr/local/mysql   3、配置文件my.cnf 3306:
default_storage_engine=Innodb innodb_locks_unsafe_for_binlog=1  
#pxc on a single physical box
wsrep_cluster_address=’gcomm://192.168.30.221:5030,192.168.30.221:6030′

wsrep_cluster_address=’gcomm://192.168.30.221:4030,192.168.30.221:5030′

wsrep_sst_method=rsync wsrep_sst_auth=sst:sampson
wsrep_node_name=node3308 innodb_autoinc_lock_mode=2  
4、启动主节点: cd /usr/local/mysql bin/mysqld_safe –defaults-file=
/data/mysql/mysql_3306/my.cnf –wsrep-new-cluster 在error.log里看到
[Note] WSREP: Shifting JOINED -> SYNCED (TO: 7) [Note] WSREP:
Waiting for SST/IST to complete. [Note] WSREP: New cluster view:
global state: f71affa6-2b55-11e7-b8db-6afbe908670d:7, view# 1: Primary,
number of nodes: 1, my index: 0, protocol version 3
则启动成功,登录mysql -uroot -p   主节点添加账号: grant usage on *.*
to ‘pxc-monitor’@’%’ identified by ‘pxc-monitor’; grant all privileges
on *.* to ‘sst’@’%’ identified by ‘sampson’;   5、启动剩下的两个节点:
bin/mysqld_safe –defaults-file=/data/mysql/mysql_3307/my.cnf
查看对应的error.log,能看到 [Note] WSREP: Shifting JOINER -> JOINED
(TO: 7) [Note] WSREP: Member 1.0 (node3307) synced with group.
[Note] WSREP: Shifting JOINED -> SYNCED (TO: 7) [Note] WSREP:
Synchronized with group, ready for connections
则表示node启动并加入cluster集群成功。   bin/mysqld_safe
–defaults-file=/data/mysql/mysql_3308/my.cnf   6、查看节点个数:
mysql> show global status like ‘wsrep_cluster_size’;
+——————–+——-+ | Variable_name      | Value |
+——————–+——-+ | wsrep_cluster_size | 3     |
+——————–+——-+ 1 row in set (0.02 sec)

    Yesterday I implemented a three-nodes
PXC,but there were some errors when proceeding it.So I decide to
research what’s wrong with it.The operations and evidences shows
below.

    When we add a new node into PXC
structure,it will estimate the mothed(IST/SST) to transfer data to the
new node.It’s no wonder that sst will be automatically choosed.What if a
dropped node in PXC by accident want to rejoin the cluster?Especially it
has been a long period of time after it was dropped out.We should avoid
starting up the node directly.As the SST(either xtrabackup-v2 or rsync
mode) will be choosed to resynchronize the dropped node instead of
IST.Generally speaking,SST may cause to decline the perormance of the
whole cluster.It’s recommend to use another way to deal with that kind
of issue.That is,slave replication.

    Today,I’m gonna implement a
PXC,Let’s see the procedure.

    Today I’m gonna test how to rescue a
dropped table from binlog server based on a full Xtrabackup backup
set.

Fisrt of all,I find out that yesterday’s
error is due to lack of “socat” package on first node
zlm2.
