chown mysql.mysql /etc/my.cnf
bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
===========================================================================
整个集群中3个MSYQL实例都关闭后，就要查看各实例的 grastate.dat 文件， 在 safe_to_bootstrap: 1
的节点上使用 bin/mysqld_safe --defaults-file=/etc/my.cnf --wsrep-new-cluster & 启动第一个实例，
其他两个实例使用 bin/mysqld_safe --defaults-file=/etc/my.cnf - & 启动。
[root@localhost data]# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: 90537b00-2ea9-11e7-a7f4-2bcbc504d8d9
seqno: 13
safe_to_bootstrap: 1
bin/mysqld_safe --defaults-file=/etc/my.cnf --wsrep-new-cluster &
或者使用下面的方法启动：
/etc/init.d/mysql bootstrap-pxc #启动第一个节点
/etc/init.d/mysql start #启动其他节点
在红帽的LINUX 上可能需要这样启动：
systemctl start mysql@bootstrap.service # 启动第一个节点
proxysql 作为 PXC 集群的代理实现读写分离
一、安装
yum -y install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm
yum -y install Percona-XtraDB-Cluster-client-57
yum -y install proxysql
service proxysql start （或者： /etc/init.d/proxysql start）
二、 MSYQL（pxc）添加 proxysql 需要用到的用户
1、添加监控用户
mysql>
CREATE USER 'monitor'@'192.168.1.%' IDENTIFIED BY 'monitor';
GRANT USAGE ON *.* TO 'monitor'@'192.168.1.%';
2、添加客户端用户
CREATE USER 'test'@'192.168.1.%' IDENTIFIED BY 'test';
GRANT all ON sbtest.* TO 'test'@'192.168.1.%';
三、配置
1、全局变量配置
mysql> \R Admin>
Admin>
-- 配置提供MSYQL代理的线程数
update global_variables set variable_value=32 where variable_name='mysql-threads';
-- 配置返回信息给客户端的MYSQL服务器版本，不论实际MYSQL服务器是什么版本都用这里配置的版本来应答客户端
update global_variables set variable_value='5.7.17' where variable_name='mysql-server_version';
--修改 proxysql 管理用户名和密码
update global_variables set variable_value='admin:passwr0d' where variable_name='admin-stats_credentials';
--修改 proxysql 监控用户名和密码
update global_variables set variable_value='stats:stats' where variable_name='admin-admin_credentials';
2、配置服务器
mysql -u admin -padmin -h 127.0.0.1 -P6032
mysql> \R Admin>
Admin>
INSERT INTO mysql_servers(hostgroup_id,hostname,port,weight) VALUES (1,'192.168.1.77',3306,1000000);
INSERT INTO mysql_servers(hostgroup_id,hostname,port,weight) VALUES (2,'192.168.1.77',3306,1);
INSERT INTO mysql_servers(hostgroup_id,hostname,port,weight) VALUES (2,'192.168.1.77',3307,1000000);
INSERT INTO mysql_servers(hostgroup_id,hostname,port,weight) VALUES (2,'192.168.1.77',3308,1000000);
INSERT INTO mysql_servers(hostgroup_id,hostname,port,weight) VALUES (1,'192.168.1.77',3307,1);
监听 3306 端口的是主库，主库同时加入了服务器组1和服务器组2，在组1的权重是100万，在服务器2的权重是1.
监听3307服务器是备库，同时加入了服务器组1和服务器组2，在组2的权重是100万，在服务器1的权重是1.
监听3308服务器是备库，加入了服务器组2，在服务器2的权重是1.
通过配置路由把select 语句路由到组2（备库），主库同时加入了组1和组2，当备库正常时在备库查询100万次才会到主库上执行一次SELECT。
监听3307服务器加入服务器组1的目的，是当主库故障时可以把写的SQL路由到改备库。如果主库正常的情况下，在主库执行100万次写的SQL才会在这台备库
执行一次写的SQL。
3、配置监控
Admin> UPDATE global_variables SET variable_value='monitor' WHERE variable_name='mysql-monitor_username';
Admin> UPDATE global_variables SET variable_value='monitor' WHERE variable_name='mysql-monitor_password';
Admin> UPDATE global_variables SET variable_value='2000' WHERE variable_name IN ('mysql-monitor_connect_interval','mysql-monitor_ping_interval','mysql-monitor_read_only_interval');
4、配置用户
INSERT INTO mysql_users(username,password,default_hostgroup,transaction_persistent) VALUES ('test','test',1,1);
transaction_persistent 设置为1，确保同一个事务的SQL路由到同一个MSYQL实例，确保开启事务的SQL路由到主库。
5、配置路由
Admin> INSERT INTO mysql_query_rules (rule_id,active,username,match_digest,destination_hostgroup,apply) VALUES (1,1,'test','^SELECT',2,0);
6、Adding Galera Support
Admin>
INSERT INTO scheduler(id,interval_ms,filename,arg1,arg2,arg3,arg4)
VALUES
(1,'10000','/usr/bin/proxysql_galera_checker','127.0.0.1','6032','0',
'/var/lib/proxysql/proxysql_galera_checker.log');
Admin> LOAD SCHEDULER TO RUNTIME;
Admin>SELECT * FROM runtime_scheduler\G
*************************** 1. row ***************************
id: 1
interval_ms: 10000
filename: /usr/bin/proxysql/proxysql_galera_checker
arg1: 127.0.0.1
arg2: 6032
arg3: 0
arg4: /var/lib/proxysql/proxysql_galera_checker.log
arg5: NULL
1 row in set (0.00 sec)
7、应用配置和把配置保存到磁盘
Admin>
LOAD MYSQL USERS TO RUNTIME;
LOAD MYSQL SERVERS TO RUNTIME;
LOAD MYSQL QUERY RULES TO RUNTIME;
LOAD MYSQL VARIABLES TO RUNTIME;
LOAD ADMIN VARIABLES TO RUNTIME
Admin>
SAVE ADMIN VARIABLES TO DISK ;
SAVE MYSQL VARIABLES TO DISK ;
SAVE MYSQL QUERY RULES TO DISK;
SAVE MYSQL SERVERS TO DISK ;
SAVE MYSQL USERS TO DISK ;
8、使用 sysbentch 测试
--OLTP 只写测试
/usr/local/sysbench/bin/sysbench --time=600 --threads=30 --mysql-user=test --mysql-password=test /usr/local/sysbench/share/sysbench/oltp_write_only.lua --mysql-host=127.0.0.1 \
--mysql-port=6033 --db-driver=mysql --tables=30 --table_size=1000 --mysql_storage_engine=innodb --report-interval=10 --db-ps-mode=disable run
--OLTP 只读测试
/usr/local/sysbench/bin/sysbench --time=300 --threads=100 --mysql-user=test --mysql-password=test /usr/local/sysbench/share/sysbench/oltp_read_only.lua \
--mysql-host=127.0.0.1 --mysql-port=6033 --db-driver=mysql --tables=30 --table_size=3000000 \
--mysql_storage_engine=innodb --report-interval=10 --db-ps-mode=disable --skip_trx=on run
-- OLTP 读写测试
/usr/local/sysbench/bin/sysbench --time=600 --threads=30 --mysql-user=test --mysql-password=test /usr/local/sysbench/share/sysbench/oltp_read_only.lua \
--mysql-host=127.0.0.1 --mysql-port=6033 --db-driver=mysql --tables=30 \
--skip_trx=on --table_size=3000000 --mysql_storage_engine=innodb --report-interval=10 --db-ps-mode=disable run
在 proxysql 服务器上部署 keepalived
1、安装 keepalived
tar vxf keepalived-1.2.18.tar.gz
cd keepalived-1.2.18
./configure --prefix=/usr/local/keepalived
make
make install
cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
2、配置 keepalived
cd /usr/local/keepalived/etc/keepalived/samples
cp keepalived.conf.vrrp.localcheck /etc/keepalived/keepalived.conf
cd /etc/keepalived/
-- 修改节点1 /etc/keepalived/keepalived.conf 文件配置内容如下：
vi keepalived.conf
! Configuration File for keepalived
vrrp_script chk_proxysql {
script "/usr/bin/mysqladmin -utest -ptest ping -h 127.0.0.1 -P 6033 > /dev/null 2>&1"
interval 5
weight -100
}
vrrp_instance VI_1 {
interface eth0
state MASTER
virtual_router_id 51
priority 150
authentication {
auth_type PASS
auth_pass hn@91A
}
virtual_ipaddress {

}
}
vrrp_instance VI_2 {

virtual_router_id 52
priority 100
authentication {
auth_type PASS
auth_pass hn@91A
}
virtual_ipaddress {
192.168.1.202/24
}
}
--节点二的 keepalived.conf 配置文件
[root@localhost keepalived]# cat keepalived.conf
! Configuration File for keepalived
vrrp_script chk_proxysql {
script "/usr/bin/mysqladmin -utest -ptest ping -h 127.0.0.1 -P 6033 > /dev/null 2>&1"
interval 5
weight -100
}
vrrp_instance VI_1 {
interface eth0
state BACKUP
virtual_router_id 51
priority 100
authentication {
auth_type PASS
auth_pass hn@91A
}
virtual_ipaddress {
192.168.1.201/24
}
}
vrrp_instance VI_2 {
interface eth0
state MASTER
virtual_router_id 52
priority 150
authentication {

auth_pass hn@91A
}
virtual_ipaddress {
192.168.1.202/24
}
track_script {
chk_proxysql
}
}
3、启动 proxysql 和 keepalived
/etc/init.d/proxysql start
/etc/init.d/keepalived start
4、在节点一关闭 proxysql
/etc/init.d/proxysql stop
--检查 /var/log/messages 日志看到已经在节点1删除VIP 1
tail -f /var/log/messages
Jun 22 11:09:29 localhost Keepalived_vrrp[26465]: bogus VRRP packet received on eth0 !!!

5、在节点1 重新启动 proxysql VIP 1 自动漂移到节点1
