注：下载 MySQL Community Server下的Source Code包 否则会出现错误 1.安装准备 配置防火墙，开启3306端口： [root@localhost src]# vi /etc/sysconfig/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT 注：这条规则应该添加到默认22端口的后面。(如上所示) 重启防火墙，使其配置生效： [root@localhost src]# /etc/init.d/iptables restart 关闭SELINUX: [root@localhost src]# vi /etc/selinux/config 在最后面添加如下信息： SELINUX=disabled :x ←保存退出 重启系统，使其生效： [root@localhost src]# shutdown -r now 查看当前版本信息： [feng@localhost Tools]$ rpm -qa|grep mysql mysql-libs-5.1.61-4.el6.x86_64 卸载当前较低版本：(需要root权限) [root@localhost Tools]# yum -y remove mysql-libs-5.1.61-4.el6.x86_64 2.安装Cmake，为MySQL编译工具(版本：cmake-2.8.9.tar.gz，在/usr/local/src目录中) 安装gcc-c++，如果没有当执行./bootstrap时报错如下： --------------------------------------------- CMake 2.8.9, Copyright 2000-2011 Kitware, Inc. C compiler on this system is: cc --------------------------------------------- Error when bootstrapping CMake: Cannot find appropriate C++ compiler on this system. Please specify one using environment variable CXX. See cmake_bootstrap.log for compilers attempted. --------------------------------------------- Log of errors: /usr/local/src/cmake-2.8.9/Bootstrap.cmk/cmake_bootstrap.log --------------------------------------------- 报错：缺少gcc-C++编译器 解决办法：安装gcc-c++编译器 [root@localhost src]# yum install gcc-c++ ←安装，选择y安装完成 [root@localhost src]# tar zxvf cmake-2.8.9.tar.gz ←解压 [root@localhost src]# cd cmake-2.8.9 [root@localhost cmake-2.8.9]# ./bootstrap ←同执行./configure [root@localhost cmake-2.8.9]# gmake ←编译 [root@localhost cmake-2.8.9]# gmake install ←安装 3.正式安装 [root@localhost src]# tar zxvf mysql-5.5.27.tar.gz [root@localhost src]# cd mysql-5.5.27 安装ncurses-devel包和bison包，否则执行cmake .时会出错 缺少ncurses-devel包信息如下： -- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH) CMake Error at cmake/readline.cmake:83 (MESSAGE): Curses library not found. Please install appropriate package, remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel. Call Stack (most recent call first): cmake/readline.cmake:127 (FIND_CURSES) cmake/readline.cmake:217 (MYSQL_USE_BUNDLED_LIBEDIT) CMakeLists.txt:268 (MYSQL_CHECK_READLINE) -- Configuring incomplete, errors occurred! 原因：缺少ncurses-devel包，需要先删除CMakeCache.txt，再进行安装 缺少bison包信息如下： Warning: Bison executable not found in PATH -- Configuring done -- Generating done -- Build files have been written to: /usr/local/src/mysql-5.5.27 原因：缺少bison包 为了避免出错，所以先安装ncurses-devel包和bison包 [root@localhost mysql-5.5.27]# yum install ncurses-devel [root@localhost mysql-5.5.27]# yum install bison 配置用户和用户组： [root@localhost mysql-5.5.27]# groupadd mysql ←添加mysql用户组 [root@localhost mysql-5.5.27]# useradd -g mysql mysql -s /bin/false ←创建mysql用户，并加入到mysql组，不允许mysql用户直接登录系统 [root@localhost mysql-5.5.27]# mkdir -p /data/mysql ←创建数据库存放目录 [root@localhost mysql-5.5.27]# chown -R mysql:mysql /data/mysql/ ←设置数据库目录权限 [root@localhost mysql-5.5.27]# mkdir -p /usr/local/mysql ←设置安装目录 [root@localhost mysql-5.5.27]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc ←别漏了有个点。 [root@localhost mysql-5.5.27]# make && make install ←时间较长 4.配置 [root@localhost mysql-5.5.27]# cd /usr/local/mysql/ [root@localhost mysql]# cp ./support-files/my-huge.cnf /etc/my.cnf ←拷贝配置文件，若存在则覆盖 [root@localhost mysql]# vi /etc/my.cnf ←编辑，在[mysqld]下增加一行 datadir = /data/mysql :x ←保存退出 [root@localhost mysql]# ./scripts/mysql_install_db --user=mysql ←生成mysql系统数据库 [root@localhost mysql]# cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld ←把mysql加入系统启动 [root@localhost mysql]# chmod 755 /etc/init.d/mysqld ←增加执行权限 [root@localhost init.d]# chkconfig mysqld on ←加入开机启动 [root@localhost init.d]# vi /etc/rc.d/init.d/mysqld ←编辑 basedir=/usr/local/mysql ←mysql程序安装路径 datadir=/data/mysql ←mysql数据存放vi 路径 [root@localhost mysql]# service mysqld start ←启动 成功则提示：Starting MySQL..... SUCCESS! 将mysql服务加入系统环境变量 [root@localhost mysql]# vi /etc/profile ←编辑 export PATH=$PATH:$JAVA_HOME/bin:/usr/local/mysql/bin ←在最后加上:/usr/local/mysql/bin [root@localhost mysql]# source /etc/profile ←使其配置生效 5.设置密码 [root@localhost bin]# ./mysqladmin -u root password 123456 ←设置成功 设置成功后重新启动！ [root@localhost mysql]# service mysqld restart 6.删除匿名用户 [feng@localhost ~]$ mysql -u root -p ←通过密码登录 Enter password: ←输入密码 mysql> select user,host,password from mysql.user; ←查看用户信息 mysql> delete from mysql.user where user=""; ←删除匿名用户 (责任编辑：IT) |
