3.编译安装

3.1编译安装percona-xtrabackup
cd /usr/local/src/percona-xtrabackup-2.4.5/
cmake ./ -DBUILD_CONFIG=xtrabackup_release \
-DWITH_MAN_PAGES=OFF \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST="/usr/local/boost"
make -j 4 && make install

3.2编译安装Percona-XtraDB-Cluster-5.7.19-29.22
编译安装前最好要卸载掉本地的mysql数据库
创建mysql用户名及文件夹
mkdir /data/mysql
ln -s /data/mysql /usr/local/mysql
mkdir /usr/local/mysql/{binlog,slow} -p
useradd mysql
chown -R mysql:mysql /usr/local/mysql

编译garbd,libgalera_smm.so
cd /usr/local/mysql
cd "percona-xtradb-cluster-galera"

获取revno值
cat GALERA-REVISION
#revno="GALERA-REVISION"
scons -j4 psi=1 --config=force revno="8678538" boost_pool=0 libgalera_smm.so
scons -j4 --config=force revno="8678538" garb/garbd

创建pxc安装目录
mkdir -p /usr/local/mysql/{bin,lib}

拷贝编译结果文件到pxc安装目录
cp garb/garbd /usr/local/mysql/bin
cp libgalera_smm.so /usr/local/mysql/lib

编译 Percona-XtraDB-Cluster-5.7.19-29.22

4.编译配置文件
vim /usr/local/mysql/my.cnf
[client]

port = 6612
default-character-set = utf8

[mysqld]
socket=/tmp/mysql.sock
basedir = /usr/local/mysql

port = 6612
server_id = 10215
pid-file = /usr/local/mysql/mysql.pid
key_buffer_size =128M
max_allowed_packet = 16M
table_open_cache = 512

sort_buffer_size = 20M
read_buffer_size = 20M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size = 32M
character-set-server=utf8

innodb_buffer_pool_size = 256M
innodb_log_file_size = 48M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1

wsrep_cluster_name = ycpxc ###指定您的群集的逻辑名称。 它必须对群集中的所有节点都相同。
wsrep_provider=/usr/local/mysql/lib/libgalera_smm.so
wsrep_cluster_address=‘gcomm://192.168.10.215,192.168.10.214‘###指定群集中节点的IP地址，节点加入群集至少需要一个，但建议列出所有节点的地址。
wsrep_sst_receive_address=192.168.10.215:6615###用于SST传送的端口
wsrep_node_incoming_address=192.168.10.215###定义节点期望客户端连接的IP地址和端口。
wsrep_provider_options = "gmcast.listen_addr=tcp://192.168.10.215;ist.recv_addr=192.168.10.215:6618;"
###gmcast.listen
###来自其他节点的地址Galera侦听连接。可以用来覆盖默认端口倾听,这是获得从连接地址。
###ist.recv_addr
###地址监听增量状态传输。
wsrep_slave_threads= 4
wsrep_log_conflicts
wsrep_node_address=192.168.10.215###集群节点地址
wsrep_sst_method=xtrabackup-v2###默认情况下，Percona XtraDB群集使用Percona XtraBackup进行状态快照传输（SST）。
wsrep_sst_auth=sstuser:passw0rd ###将SST的身份验证凭据指定为<sst_user>：<sst_pass>。 您必须创建此用户
wsrep_log_conflicts
wsrep_retry_autocommit=8
secure_file_priv=""
innodb_page_cleaners=8

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash
port = 6612
default-character-set = utf8
socket=/tmp/mysql.sock

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 256M
read_buffer = 2M
write_buffer = 2M

[mysqlhotcopy]
interactive-timeout

注意：在[client]、[mysqld]、[mysql]最好都要指定sock的位置，避免初始化和启动时报错去找默认的配置文件。

4.1为wsrep_sst_auth传输创建用户
当引导第一个节点并为其提供必要的权限时：
mysql> CREATE USER ‘sstuser‘@‘localhost‘ IDENTIFIED BY ‘passw0rd‘;
mysql> GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON . TO ‘sstuser‘@‘localhost‘;
mysql> FLUSH PRIVILEGES;

5.初始化启动pxc主节点
chmod +x /usr/local/mysql/my.cnf
chown -R mysql:mysql /usr/local/mysql
su - mysql
/usr/local/mysql/bin/mysqld --defaults-file=./my.cnf --initialize --wsrep-new-cluster &
#要指定配置文件来初始化
#初始化有问题可以清空msyql/data/目录下的文件
#记录密码
#注意主节点启动要加上--wsrep-new-cluster，其他节点不用。

###用刚刚初始化的密码进去MySQL
/usr/local/mysql/bin/mysql -uroot -p${mypasswd}
###第一次进去会提示改密码
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘123456‘;

6.配置其他节点
安装方式都是和主节点是一样的，注意要卸载掉原来的mysql，更改配置文件的集群信息和server_id 即可。
只列出差异部分：
server_id = 10214
wsrep_sst_receive_address=192.168.10.214:6615###用于SST传送的端口
wsrep_node_incoming_address=192.168.10.214###定义节点期望客户端连接的IP地址和端口。
wsrep_provider_options = "gmcast.listen_addr=tcp://192.168.10.214;ist.recv_addr=192.168.10.214:6618;"
wsrep_node_address=192.168.10.215###集群节点地址

6.1启动其他节点
#其它节点直接启动不用再创建用户和密码
/usr/local/mysql/bin/mysqld --defaults-file=../my.cnf

7.使用garbd
pxc集群最少是要3台，如果没有，可以使用仲裁者garbd，用来解决
可以找在一个网段的服务器上。也可以就在已有的节点上但是注意默认的端口不要冲突
#启用garbd
cd /usr/local/mysql/bin/
./garbd -a gcomm://192.168.10.214,192.168.10.215 -g ycpxc -l /usr/local/mysql/data/garbd.log -d
#全部起完了之后就可以看到节点数和集群

8.检查
#查看MySQL 节点数
mysql> show global status like ‘wsrep_cluster_size‘;
+--------------------+-------+
| Variable_name | Value |
+--------------------+-------+
| wsrep_cluster_size | 3 |
+--------------------+-------+
1 row in set (0.00 sec)
是三个表示pxc集群搭建成功，可以在一个节点上创建一张表，启动节点可以查询的到说明集群运行正常。
