[root@wwwlxg bin]# ./mysqld --initialize --user=mysql --basedir=/opt/mysql/mysql --datadir=/opt/mysql/mysql/data

<小时/> 这是my.cnf

# These are commonly set, remove the # and set as required.
 basedir = /opt/mysql/
datadir = /opt/mysql/data
 port = 3306
server_id = 1
socket = /tmp/mysql.sock
lc_messages_dir = /opt/mysql/data
language = /opt/mysql/share/english

有关于＆＃39; lc-messages-dir＆＃39;的错误我想知道那是什么以及如何解决它？（这个问题已经解决了）因为我将它添加到my.cnf：lc_messages_dir = / opt / mysql / data

当mysql.server启动时出现

另一个错误

ps -ef|grep mysql
no other mysql is running 
ls -l /opt/mysql
im sure /opt/mysql is  mysql:mysql

Starting MySQL... ERROR! The server quit without updating PID file (/opt/mysql/data/wwwlxg.pid).

即时运行：centos6.4 mysql-5.7.17-linux-glibc2.5-x86_64

Answer 1

试

的my.cnf

[mysqld]
...
lc_messages_dir = /opt/mysql/share
lc_messages = en_US

errmsg.sys通常位于/ {mysql-path} / mysql / share / {language} /，{language}将是'english'，'spanish'...

Answer 2

您必须在一行中将--defaults-file =＃作为第一个参数，如下所示：

./bin/mysqld  --defaults-file=my57.cnf --initialize

希望对您有所帮助：）

Answer 3

看起来文件errmsg.sys的路径不存在。检查文件夹/opt/mysql/mysql/data是否存在，如果不存在，请创建它。也许您还必须使用chown mysql:mysql /opt/mysql/mysql/data调整此文件夹的权限。

Answer 4

通常，在安装MySQL时，通常会在/ usr / share / mysql-中在系统中创建用于lc_messages配置的目录。

在 my.cnf 中为此的正确配置如下（在我的情况下为MySQL 8.0）：

[mysqld]
lc-messages-dir                         = /usr/share/mysql-8.0
lc-messages                             = en_US

如果直接在lc-message-dir中指定 errmsg.sys 所在的语言（例如/usr/share/mysql-8.0/english），那么您将收到以下警告：

使用5.5之前的语义从中加载错误消息 /usr/share/mysql-8.0/english/。如果这不是故意的，请参阅有效使用--lc-messages-dir和--language的文档参数。

关键是正确使用 lc-messages-dir 和 lc-messages 。

什么导致错误的关于＆＃39; lc-messages-dir＆＃39;当我初始化mysql-5.7.17时
