Centos安装mysql实例教程

上传mysql-5.6.4-m7.tar.gz和cmake-3.1.0.tar.gz到/usr/local文件夹下。

CentOS安装g++和ncurses-devel[root@localhost local]# yum install gcc-c++ [root@localhost local]# yum install ncurses-devel

cmake的安装[root@localhost]# tar -zxv -f cmake-3.1.0.tar.gz // 解压压缩包 [root@localhost local]# cd cmake-3.1.0 [root@localhost cmake-3.1.0]# ./configure [root@localhost cmake-3.1.0]# make [root@localhost cmake-3.1.0]# make install

将cmake永久加入系统环境变量用vi在文件/etc/profile文件中增加变量，使其永久有效， [root@localhost local]# vi /etc/profile在文件末尾追加以下两行代码： PATH=/usr/local/cmake-3.1.0/bin:$PATH export PATH执行以下代码使刚才的修改生效： [root@localhost local]# source /etc/profile用 export 命令查看PATH值 [root@localhost local]# echo $PATH

创建mysql的安装目录及数据库存放目录[root@localhost]# mkdir -p /usr/local/mysql //安装mysql [root@localhost]# mkdir -p /usr/local/mysql/data //存放数据

创建mysql用户及用户组[root@localhost] groupadd mysql [root@localhost] useradd -r -g mysql mysql

编译安装mysql[root@localhost local]# tar -zxv -f mysql-5.6.4-m7.tar.gz //解压 [root@localhost local]# cd mysql-5.6.4-m7 [root@localhost mysql-5.6.4-m7]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DMYSQL_USER=mysql \ -DMYSQL_TCP_PORT=3306 [root@localhost mysql-5.6.4-m7]# make [root@localhost mysql-5.6.4-m7]# make instal

检验是否安装成功[root@localhost mysql-5.6.4-m7]# cd /usr/local/mysql/ [root@localhost mysql]# ls bin COPYING data docs include INSTALL-BINARY lib man mysql-test README scripts share sql-bench support-files 有bin等以上文件的话，恭喜你已经成功安装了mysql

设置mysql目录权限[root@localhost mysql]# cd /usr/local/mysql //把当前目录中所有文件的所有者设为root，所属组为mysql [root@localhost mysql]# chown -R root:mysql . [root@localhost mysql]# chown -R mysql:mysql data

将mysql的启动服务添加到系统服务中[root@localhost mysql]# cp support-files/my-medium.cnf /etc/my.cnf cp：是否覆盖'/etc/my.cnf'？

创建系统数据库的表[root@localhost mysql]# cd /usr/local/mysql [root@localhost mysql]# scripts/mysql_install_db --user=mysq

设置环境变量[root@localhost ~]# vi /root/.bash_profile 在修改PATH=$PATH:$HOME/bin为： PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib [root@localhost ~]# source /root/.bash_profile //使刚才的修改生

手动启动mysql[root@localhost ~]# cd /usr/local/mysql [root@localhost mysql]# ./bin/mysqld_safe --user=mysql & //启动MySQL，但不能停止 mysqladmin -u root -p shutdown //此时root还没密码，所以为空值，提示输入密码时，直接回车即可

将mysql的启动服务添加到系统服务中[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysq

启动mysql[root@localhost mysql]# service mysql start Starting MySQL... ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).启动失败： 我这里是权限问题，先改变权限 [root@localhost mysql]# chown -R mysql:mysql /usr/local/mysql接着启动服务器 [root@localhost mysql]# /etc/init.d/mysql star

修改MySQL的root用户的密码以及打开远程连接[root@localhost mysql]# mysql -u root mysqlmysql> use mysql; mysql> desc user; mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'root'; //为root添加远程连接的能力 mysql> update user set Password = password('123456') where User='root'; //设置root用户密码 mysql> select Host,User,Password from user where User='root'; mysql> flush privileges; mysql> exit

重新登录[root@localhost mysql]# mysql -u root -p Enter password:123456若还不能进行远程连接，关闭防火墙 [root@localhost]# /etc/rc.d/init.d/iptables stop
