在linux（centos）下有2种方式安装，第一种使用rpm安装在网上可以搜到，第二种使用压缩包方式，我这里是采用压缩包方式。
1.这里我将mysql安装在/usr/local/mysql目录里面，也可以安装在其他地方
mkdir /usr/local/mysql
2.下载mysql压缩包
wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz 3.解压并复制 tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz mv mysql-5.7.11-Linux-glibc2.5-x86_64/* /usr/local/mysql/ 4.创建data目录 mkdir /usr/local/mysql/data 5.创建mysql用户和修改权限 groupadd mysql chown -R mysql.mysql /usr/local/mysql/ 6.初始化数据 [root@localhost mysql] ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 2016-01-20 02:47:35 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-01-20 02:47:45 [WARNING] The bootstrap log isn't empty: 2016-01-20 02:47:45 [WARNING] 2016-01-19T18:47:36.732678Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead 2016-01-19T18:47:36.750527Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000) 2016-01-19T18:47:36.750560Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)7. 复制配置文件到 /etc/my.cnf
cp -a ./support-files/my-default.cnf /etc/my.cnf (选择y) 8. mysql的服务脚本放到系统服务中 cp -a ./support-files/mysql.server /etc/init.d/mysqld 修改my.cnf文件 # These are commonly set, remove the # and set as required. basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 # server_id = ..... socket = /tmp/mysql.sock character-set-server = utf8 # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M 9.启动mysql service mysqld start 10.修改mysql密码 [root@localhost mysql]# mysql -u root mysql mysql>update user set authentication_string=PASSWORD('你的密码') where user='root';
10.创建快捷方式
ln -s /usr/local/mysql/bin/mysql /usr/bin该实验亲测可是安装成功。在安装过程中可能会遇到问题，到网上查一下。
