Percona XtraDB Cluster (PXC) 總算出 5.5.29 版本了…

剛剛看到 Percona XtraDB Cluster 5.5.29-23.7.1 的公告了:「Announcing Percona XtraDB Cluster 5.5.29-23.7.1」。

除了修正 bug 外,有很多是讓設定變得簡單的調整 (變得比較不容易中地雷,或是錯誤訊息比較清楚,而非靠 Google 找到答案),像是:

Variable wsrep_node_name was initialized before the glob_hostname, which lead to empty value for wsrep_node_name if it wasn’t set explicitly. Bug fixed #1081389 (Alex Yurchenko).

Percona XtraDB Cluster would crash when binlog_format was set to STATEMENT. This was fixed by introducing the warning message. Bug fixed #1088400 (Seppo Jaakola).

Percona XtraDB Cluster would crash if the node’s own address would be specified in the wsrep_cluster_address variable. Bug fixed #1099413 (Alexey Yurchenko).

該來安排測試了…

    我在 RHEL 的環境中嘗試架設 3 個 node 的 Cluster
    一直無法啓動,除非設定 gcomm:// 爲空,但這樣就變成單機了對吧?

    第一台需要設 gcomm://,後面幾台不用。確認是否為 cluster mode 可以看 wsrep_cluster_size 是否大於 1。
