linux安装mysql-5.6.26 查看工具:winscp 下载地址 http://mirrors.sohu.com/mysql/MySQL-5.6/ 文件: mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz 解压 tar -xzf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz 注:安装目录需要设置到解压目录,否则报以下错误 FATAL ERROR: Could not find ./bin/my_print_defaults 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. or FATAL ERROR: Could not find my-default.cnf 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. 将解压的目录放到/usr/local下改为mysql或添加软连接 mv mysql-5.6.26-linux-glibc2.5-x86_64 mysql or ln -s /www/mysql-5.6.26-linux-glibc2.5-x86_64 /usr/local/mysql 增加mysql用户和组 groupadd mysql useradd -r -g mysql mysql 修改mysql目录及子文件属主和属组 chown -R mysql:mysql mysql 进入mysql目录并安装 cd mysql scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 安装过程可能缺少某些文件,一般用 yum install -y xxx 按需安装即可. 实现使用 service mysqll (start|status|stop) 命令操作mysql. cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 错误: [root@localhost mysql]# mysql -bash: mysql: command not found 解决:配置环境变量,把 export PATH=$PATH:/usr/local/mysql/bin添加到 /etc/profile中, source /etc/profile重新加载环境变量, service mysql start启动mysql服务。 错误: [root@localhost mysql]# mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) 解决: mysql --socket=/var/lib/mysql/mysql.sock ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock 启动成功 mysql> select version(); +-----------+ | version() | +-----------+ | 5.6.26 | +-----------+ 1 row in set (0.00 sec) 成功后可能需要往mysql的user表增加新账号 错误:指定了严格模式,为了安全,严格模式禁止通过insert 这种形式直接修改mysql库中的user表进行添加新用户 1364 - Field 'ssl_cipher' doesn't have a default value 解决: vim /usr/local/mysql/my.cnf sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 改为 sql_mode=NO_ENGINE_SUBSTITUTION 修改密码: mysql>UPDATE user SET password=PASSWORD('1') where USER='root'; 允许使用用户名root密码1从任何主机连接到mysql服务器 该创建的root账号只是从外部访问的账号,与内部linux访问该mysql时所用root不同,内部linux访问该mysql的root账号也不是linux的系统root账号 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1' WITH GRANT OPTION; 刷新权限 mysql>FLUSH PRIVILEGES; MySql提示:The server quit without updating PID file(…)失败 可能进程里已经存在mysql进程 解决方法:用命令“ps -ef|grep mysqld”查看是否有mysqld进程,如果有使用“kill -9 进程号”杀死,然后重新启动mysqld! 查看CentOS linux版本: cat /etc/issue root@DB-02 ~]# mysql -u root -bash: mysql: command not found 原因:这是由于系统默认会查找/usr/bin下的命令,如果这个命令不在这个目录下,当然会找不到命令,我们需要做的就是映射一个链接到/usr/bin目录下,相当于建立一个链接文件。 首先得知道mysql命令或mysqladmin命令的完整路径,比如mysql的路径是:/usr/local/mysql/bin/mysql,我们则可以这样执行命令: # ln -s /usr/local/mysql/bin/mysql /usr/bin (责任编辑:IT) |
