Linux主机Percona5.7.11安装(直接解压初始化方式)_ubuntu apt percona-server-5.7

主机Percona安装(直接解压初始化方式)

下载版本：Percona-Server-5.7.11-4-Linux.x86_64.ssl101.tar.gz
解压：

	tar -zxvf Percona-Server-5.7.11-4-Linux.x86_64.ssl101.tar.gz
1

(以下方式不使用mysql默认的路径/usr/local/mysql;使用自定义路径)

前提条件：确保创建有效的basedir,datadir,socket路径目录

1、初始化数据库：

./mysql_install_db --user=jfshop --basedir=/app/soft/Percona-Server-5.7.11 --datadir=/app/soft/perdata
1

启动mysql数据库

./mysqld --defaults-file=/app/soft/conf/my.cnf --basedir=/app/soft/Percona-Server-5.7.11
1

登陆数据库

./mysql -u root -p --socket=/app/soft/log/per.sock
1

---

补充：
如果直接使用命令./mysql -u root -pmysql默认会找/tmp/mysql.sock因此若是为了方便可以在my.cnf中直接这样写socket= /tmp/mysql.sock

---

my.cnf文件的最后添加一下内容跳过密码验证

skip-grant-tables
1

进入mysql面板后修改密码：

UPDATE user SET Password = PASSWORD('password') WHERE user = 'root';
1

修改以后删除my.cnf 中的跳过验证
重启mysql服务
进入mysql面板后需进行一下操作：

ALTER USER USER() IDENTIFIED BY 'password';
1

自定义目录下的my.cnf

修改mysql使其允许被远程访问：

	root用户的 host 属性 改为 %  即可

刷新权限：

‘./mysql-bin.index’ not found (Errcode: 13) 的解决方法

将文件系统复制到PC机上，然后再拷贝到别的SD卡后，发现mysql无法启动了，首先检查了一下mysql的错误日志，发现最后出现以下错误：

/usr/local/mysql/libexec/mysqld: File './mysql-bin.index' not found (Errcode: 13)
1

提示./mysql-bin.index无法找到（由于mysql开启了bin日志功能），到数据库根目录查看该文件是存在的，可能是文件权限的问题，查看了数据库根目录的权限是700，所有者和用户组都是root，可能是上次转移数据库的时候不小心修改了文件夹的权限。
解决方法：

chgrp -R mysql /app/soft/log && chown -R mysql /app/soft/log
1

重新启动mysql [OK]
