4 查看安装位置
whereis mysql
mysql: /usr/bin/mysql /usr/lib64/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz
5.设置目录用户组权限
[ mysql]# chown -R mysql:mysql /usr/share/mysql/
[ mysql]# chown -R mysql:mysql /var/lib/mysql
6.设置mysql目录 运行初始化权限表
[ mysql]# find / -name ‘mysql_install_db‘
/usr/bin/mysql_install_db
会报错
/usr/bin/mysql_install_db --user=mysql --basedir=/usr/share/mysql --datadir=/var/lib/mysql
FATAL ERROR: Could not find /fill_help_tables.sql
If you compiled from source, you need to run ‘make install‘ to
copy the software into the correct location ready for operation.
If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
似乎是编译安装方式 使用cmake 等安装方式才需要
7 提示 RSA private key file not found: /var/lib/mysql//private_key.pem. Some authentication plugins will not work.
参考生成密钥 解决 https://blog.csdn.net/zhengwei125/article/details/53097365
需要移动到指定目录 /var/lib/mysql//private_key.pem.
8 启动log报错
Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.user‘ doesn‘t exist
查证后是 /var/lib/mysql/mysql 里面的数据库初始化没完成
使用命令
/usr/bin/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/share/mysql/ --datadir=/var/lib/mysql --user=mysql
报错
[ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.user‘ doesn‘t exist
正确的命令格式是 /share/mysql/ 的目录查找在安装命令中已经代入了
/usr/bin/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr --datadir=/var/lib/mysql --user=mysql
