centos6.5使用rpm包安装MySQL8.0.22，安装完成后，启动数据库初始化报错：Failed to open the bootstrap file /var/lib/mysql-files/install-validate-password-plugin.2SvMB2.sql
先看日志，具体报错如下：
# 安装完成后，启动报错[root@nybzapp2 tools]# service mysqld start初始化 MySQL 数据库： [失败][root@nybzapp2 tools]# cat /var/log/mysqld.log 2021-01-10T00:45:48.811506Z 0 [System] [MY-013169] [Server] /usr/sbin/mysqld (mysqld 8.0.22) initializing of server in progress as process 63872021-01-10T00:45:49.112961Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.2021-01-10T00:45:53.812354Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.2021-01-10T00:45:59.156489Z 0 [ERROR] [MY-013129] [Server] A message intended for a client cannot be sent there as no client-session is attached.

因为之前安装过许多次各个版本的MySQL，从未遇到此错误。服务器之前也没有安装过MySQL，而且安装后并没有修改任何默认配置直接启动的，我也是一脸懵逼了。
然后各种百度，仍然是找不到答案。最后，查看安装记录找到了问题所在，如下：

解压安装包后，一共是8个rpm包，而我通过解决依赖，只安装了5个就成功安装了mysql-community-server，所以没注意少了安装了mysql-community-libs-compat-8.0.22-1.el6.x86_64.rpm
安装mysql-community-libs-compat-8.0.22-1.el6.x86_64.rpm包
[root@nybzapp2 tools]# rpm -ivh mysql-community-libs-compat-8.0.22-1.el6.x86_64.rpm warning: mysql-community-libs-compat-8.0.22-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... ########################################### [100%] 1:mysql-community-libs-co########################################### [100%]
再次启动数据库：
[root@nybzapp2 tools]# service mysqld startStarting mysqld: [ OK ][root@nybzapp2 tools]#
问题解决
