mysql----Linux下安装
一、安装环境
操作系统：linux
Mysql版本：mysql-5.6.24
二、所需软件
mysql-5.6.24.tar.gz
三、安装步骤
（1）上传安装包
mkdir /usr/setup
上传mysql-5.6.24.tar.gz到/usr/setup
（2）安装依赖
yum -y install make cmake gcc-c++ bison-devel ncurses-devel openssl-devel.x86_64
（3） 检验是否已经安装mysql
查找系统里是否已经安装了mysql数据库的相关组件，使用命令：
rpm -qa | grep mysql
进行查找，如果查找到，可以使用下面命令进行强制卸载：
rpm -e --nodeps 包名。
（4） 编译安装
cd /usr/setup/ tar -zxvf mysql-5.6.24.tar.gz cd mysql-5.6.24 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql\ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DSYSCONFDIR=/etc \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_SSL=yes
make make install
（5）创建用户
groupadd mysql useradd -g mysql mysql chown mysql.mysql /usr/local/mysql�CR
（6）初始化数据库文件
/usr/local/mysql/scripts/mysql_install_db--user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data
（7） 复制mysql配置文件和启动文件
cp /usr/setup/mysql-5.6.24/support-files/my-default.cnf/etc/my.cnf cp/usr/setup/mysql-5.6.24/support-files/mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld vi /etc/my.cnf [mysqld] ##添加下面的内容 datadir =/usr/local/mysql/data socket =/var/lib/mysql/mysql.sock basedir =/usr/local/mysql/ port = 3306 server_id = 1 report-port =3306
（8）启动mysql
/etc/init.d/mysqld start
（9） 登录
/usr/local/mysql/bin/mysql -uroot-p 默认没有密码。
（10）修改密码
/usr/local/mysql/bin/mysqladmin -uroot password 'mysql' 登录测试 /usr/local/mysql/bin/mysql �Curoot -p
（11） 其它配置
设置开机自启动 chkconfig mysqld on chkconfig --list|grep mysql 添加mysql的环境变量 vi /etc/profile PATH=/usr/local/mysql/bin:$PATH export PATH source /etc/profile 删除空用户 mysql -uroot -p use mysql; selectdistinct(user) from user; delete from userwhere user=''; flushprivileges; selectdistinct(user) from user;
