PXC 安裝 for 5.7

系統centos7及以上版本

　　

安裝依賴包：

yum install perl-IO-Socket-SSL perl-DBD-MySQL perl-Time-HiRes socat nc -y

yum install –y openssl openssl-develxtrabackup

若是提示已經安裝，可使用
#updatedb
#locate libssl.so 看看能不能找到 而後用
# ldd /usr/local/mysql/bin/mysqld 查看還有那些依賴需安裝安裝：

rpm -qa|grep openssl

yum localinstall percona-xtrabackup-24-2.4.9-1.el6.x86_64.rpm

vim /etc/ld.so.conf.d/mysql.conf

下載軟件包

wget https://www.percona.com/downloads/Percona-XtraDB-Cluster-LATEST/Percona-XtraDB-Cluster-5.7.22-29.26/binary/tarball/Percona-XtraDB-Cluster-5.7.22-rel22-29.26.1.Linux.x86_64.ssl102.tar.gz

node1

初始化：

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf --initialize

啓動：

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf --wsrep-new-cluster &

登陸修改密碼

cat data/error.log |grep password

mysql -S /tmp/mysql3366.sock -uroot -p

alter user() identified by 'zyqzyq';

建立一個作sst的帳號

grant reload, lock tables, replication client, process on . to  'sst'@'localhost' identified by 'zyqzyq';

node2

初始化

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf --initialize

啓動 

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf &

node3

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf --initialize

/letv/usr/local/mysql/bin/mysqld --defaults-file=/letv/mysql/mysql3366/etc/my3366.cnf &
