如何在 x86 服务器上安装 Percona XtraDB Cluster？

我将从 MySQL 复制迁移到Percona XtraDB集群。我面临的问题是一个节点在 x86 上运行，我无法Percona-XtraDB-Cluster-server从Percona 仓库由于解决的问题：

...
--> Finished Dependency Resolution
1:Percona-XtraDB-Cluster-server-5.5.27-23.6.356.rhel5.i686 from percona has depsolving problems
  --> Missing Dependency: Percona-XtraDB-Cluster-galera is needed by package 1:Percona-XtraDB-Cluster-server-5.5.27-23.6.356.rhel5.i686 (percona)
Error: Missing Dependency: Percona-XtraDB-Cluster-galera is needed by package 1:Percona-XtraDB-Cluster-server-5.5.27-23.6.356.rhel5.i686 (percona)
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

正如你所见，Percona-XtraDB-Cluster-galera不存在回购。

我该如何解决这个问题？

不知道为什么Percona-XtraDB-Cluster-galeraPercona 仓库中缺少这个。但你可以从源代码编译。

首先，下载并安装Galera wsrep 提供商：

Name        : galera                       Relocations: (not relocatable)

二、下载Percona-XtraDB-Cluster的源代码并安装关注这指南。请注意，由于您运行的是 x86，请通过运行以下命令来构建二进制文件：

# cd Percona-XtraDB-Cluster-5.5.27
# BUILD/compile-pentium-wsrep
# make install

第三，将其更改/etc/my.cnf为如下内容：

[mysqld]
# Percona XtraDB Cluster
binlog_format=ROW

wsrep_provider=/usr/lib/galera/libgalera_smm.so

wsrep_slave_threads=2
wsrep_cluster_name=trimethylxanthine
wsrep_sst_method=rsync
wsrep_node_name=node2

innodb_locks_unsafe_for_binlog=1
innodb_autoinc_lock_mode=2


[mysqld_safe]
wsrep_urls=gcomm://192.168.1.100:4567, \
           gcomm://192.168.1.200:4567, \
           gcomm://192.168.1.300:4567, \
           gcomm://

不要忘记调整初始化脚本/etc/init.d/mysql以指向相应的 MySQL 二进制文件：

if test -z "$basedir"
then
  basedir=/usr
  #bindir=/usr/bin
  bindir=/usr/local/mysql/bin
  if test -z "$datadir"
  then
    datadir=/var/lib/mysql
  fi
  sbindir=/usr/sbin
  libexecdir=/usr/sbin
else
...
