MySQL PXC部署實踐

文章借鑑：https://www.cnblogs.com/zejin2008/p/5475285.html yum安裝： wget https://www.percona.com/downloads/Percona-XtraDB-Cluster-LATEST/Percona-XtraDB-Cluster-5.7.24-31.33/binary/redhat/6/x86_64/Percona-XtraDB-Cluster-5.7.24-31.33-r443-el6-x86_64-bundle.tar 二進制安裝： • ssl100: for Debian prior to 9 and Ubuntu prior to 14.04 versions • ssl101: for CentOS 6 and CentOS 7 • ssl102: for Debian 9 and Ubuntu versions starting from 14.04 wget https://www.percona.com/downloads/Percona-XtraDB-Cluster-LATEST/Percona-XtraDB-Cluster-5.7.24-31.33/binary/tarball/Percona-XtraDB-Cluster-5.7.24-rel26-31.33.1.Linux.x86_64.ssl100.tar.gz • 3306 is used for MySQL client connections and SST (State Snapshot Transfer) via mysqldump. • 4444 is used for SST via rsync and Percona XtraBackup. • 4567 is used for write-set replication traffic (over TCP) and multicast replication (over TCP and UDP). • 4568 is used for IST (Incremental State Transfer). 測試環境部署：192.168.1.221，192.168.1.222，192.168.1.223 環境準備 全部節點如下配置： mkdir -p /data/mysql/3307/{binlog,conf,data,log,pid,socket,tmp} chown -R mysql.mysql /data/mysql mv Percona-XtraDB-Cluster-5.7.24-rel26-31.33.1.Linux.x86_64.ssl101 /usr/local/Percona-XtraDB-Cluster-5.7.24 每個節點都需要按照xtrabackup工具，否則後面兩個節點無法啓動 wget https://repo.percona.com/yum/percona-release-1.0-7.noarch.rpm rpm -ivh percona-release-1.0-7.noarch.rpm yum -y install percona-xtrabackup-24.x86_64 如報錯： Requires: libev.so.4()(64bit) 則：wget ftp://rpmfind.net/linux/atrpms/el6-x86_64/atrpms/stable/libev-4.04-2.el6.x86_64.rpm rpm -ivh libev-4.04-2.el6.x86_64.rpm 同時版本要匹配，percona-xtrabackup-80-8.0.5只使用percona 8.0 每個節點安裝socat，socat版本儘量在1.7.3以上 yum install socat 或者 wget http://www.dest-unreach.org/socat/download/socat-1.7.3.2.tar.gz ./configure && make && make install 192.168.1.221修改配置文件，增加如下： wsrep_provider=/usr/local/Percona-XtraDB-Cluster-5.7.24/lib/libgalera_smm.so wsrep_cluster_name=pxc-cluster wsrep_cluster_address=gcomm://192.168.1.221,192.168.1.222,192.168.1.223 wsrep_node_name=pxc1 wsrep_node_address=192.168.1.221 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 192.168.1.222按192.168.1.221增加的修改配置文件如下： ....... wsrep_node_name=pxc2 wsrep_node_address=192.168.1.222 ........ 192.168.1.222按192.168.1.221增加的修改配置文件如下： ........ wsrep_node_name=pxc3 wsrep_node_address=192.168.1.223 ........ 集羣第一個節點：221 初始化： /usr/local/Percona-XtraDB-Cluster-5.7.24/bin/mysqld --defaults-file=/data/mysql/3307/conf/my.cnf --user=mysql --initialize 啓動，集羣中第一個節點啓動要加選項 --wsrep-new-cluster /usr/local/Percona-XtraDB-Cluster-5.7.24/bin/mysqld_safe --defaults-file=/data/mysql/3307/conf/my.cnf --user=mysql --wsrep-new-cluster & 授權 CREATE USER 'sstuser'@'localhost' IDENTIFIED BY 'passw0rd'; GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO 'sstuser'@'localhost'; 節點222，223： /usr/local/Percona-XtraDB-Cluster-5.7.24/bin/mysqld --defaults-file=/data/mysql/3307/conf/my.cnf --user=mysql --initialize /usr/local/Percona-XtraDB-Cluster-5.7.24/bin/mysqld_safe --defaults-file=/data/mysql/3307/conf/my.cnf --user=mysql &
