Percona DB 无法启动：initscript mysql，操作“启动”失败

安装 Percona 服务器后，我收到以下消息：

 * Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
 * Run the following commands to create these functions:

    mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
    mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
    mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

 * See http://www.percona.com/doc/percona-server/5.6/management/udf_percona_toolkit.html for more details

我不明白为什么它无法启动。

我正在运行 Ubuntu 15。1GB 的 RAM......

答案1

错误消息“Package percona-server-server-5.6 is not configure yet.”表示软件包未安装。Percona 软件包需要按正确的顺序安装：
首先从通用库开始，然后是客户端，然后是服务器端。

当您使用 dpkg 安装时，您将看到 dpkg 报告的任何错误，这些错误必须先解决。有时，只需运行 apt-get -f install 即可通过安装所需的软件包来解决问题。

对于 Ubuntu 14.04：

dpkg-i percona-server-common-5.6_5.6.26-74.0-1.trusty_amd64.deb percona-server-client_5.6.26-74.0-1.trusty_amd64.deb percona-server-server-5.6_5.6.26-74.0-1.trusty_amd64.deb

一旦 dpkg 没有错误，您就可以开始了。

要强制安装包而不启动 MySQL 服务，请运行：

RUNLEVEL=1 apt install -y percona-xtradb-cluster-57

来源：安装软件包而不启动后台进程和服务。

安装软件包后它将停止守护进程的启动。

目前还不清楚为什么你的Percona 服务器无法启动 MySQL 服务器，要检查详细信息，请运行：

journalctl -xe

或者检查 MySQL 日志：

tail -n50 /var/log/mysqld.log

最常见的问题是安装/启动Percona 服务器由于集群配置尚未完成，因此服务无法连接到现有集群。

如果是，请检查 中的配置文件/etc/mysql/percona-xtradb-cluster.conf.d/，尤其wsrep_cluster_address是wsrep.cnf。在首次启动服务之前，请先尝试取消注释。

也可以看看：在 Ubuntu 上无人值守安装 Percona/MySQL。

对于文档页面，请检查：Percona XtraDB Cluster 5.7 文档。
