mysql5.5以上的版本编译需要 cmake
1 、安装cmake
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz tar -zxvf cmake-2.8.10.2.tar.gz cd cmake-2.8.10.2 ./configure make make install make clean 到此 cmake安装完毕
2 、安装 mysql
1 下载mysql
官方下载地址 http://dev.mysql.com/downloads/mysql
选择Source Code
我下载的是 Generic Linux (Architecture Independent), Compressed TAR Archive 这个版本(当前的版本是5.6.26)
把下载好的文件上传到linux服务器
或者直接 wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.26.tar.gz
2 检查是否已经安装了mysql
rpm -qa | grep mysql (如果已经安装了需先卸载) rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64 (卸载mysql 卸载版本名称以实际的为准)
3 安装mysql
yum -y install make gcc-c++ bison-devel ncurses-devel //安装mysql所需要的依赖包
groupadd mysql （增加mysql用户组） useradd -g mysql -s /sbin/nologin mysql (增加mysql用户 不允许直接登录) tar -zxvf mysql-5.6.26.tar.gz cd mysql-5.6.26 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 (cmake 编译mysql)
make make install make clean chown -R mysql:mysql /usr/local/mysql chmod 755 /usr/local/mysql/scripts/mysql_install_db (赋给文件执行权限) /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chmod 755 /etc/init.d/mysqld chkconfig --add mysqld chkconfig mysqld on
编辑 /etc/init.d/my.cnf //mysql的配置文件写入如下内容 根据实际情况修改

service mysqld restart 添加到环境变量 vi /etc/profile 添加如下代码 export PATH="$PATH:/usr/local/mysql/bin" source /etc/profile 登录mysql mysql -uroot -p //登陆mysql 第一次登陆的时候不需要输入密码 use mysql; delete from user where User=''; //删除用户名为空的用户 UPDATE user SET password=PASSWORD("123456") WHERE user='root'; //修改root用户的密码 mysql增加用户的命令 grant all privileges on db_test.* to db_user@"%" identified by '123456' with grant option; 这样就为 数据库 db_test 增加了一个 db_user的用户操作的权限 默认密码为 123456 flush privileges;//刷新权限
重启服务器，看mysql是否随着开机启动
