1.安装cmake
MySQL从5.5版本开始,通过./configure进行编译配置方式已经被取消,取而代之的是cmake工具。因此,我们首先要在系统中源码编译安装cmake工具。# wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz
# tar zxvf cmake-2.8.4.tar.gz
# cd cmake-2.8.4
# ./configure
# make# make install2.确保以下所需系统软件包已经被安装
通过 rpm -qa | grep name 的方式验证以下软件包是否已全部安装。gcc* gcc-c++* autoconf* automake* zlib* libxml* ncurses-devel* libgcrypt* libtool*如果缺少相关的软件包,可通过yum -y install 的方式在线安装,或直接从系统安装光盘中找到并通过rpm -ivh 的方式安装。
3. 安装前的系统设置
建立mysql安装目录及数据存放目录# mkdir /opt/mysql# mkdir /opt/mysql/data创建用户和用户组
# groupadd mysql# useradd -g mysql mysql赋予数据存放目录权限
# chown mysql:mysql -R /opt/mysql/data4.从configure更换为cmake
我相信大多数人都已经习惯了之前的configure方式,并且所使用的参数也是比较个性化的,换成cmake之后,这一方面会带来不少的麻烦。还好,MySQL的官方网站提供了二者的参数对照表,我们可以尽可能的保留之前的参数,来编译配置新的MySQL版本。configure 与 cmake 参数对照指南:
以我自己为例,之前我一直使用的参数为:
./configure --prefix=/opt/mysql/ \--sysconfdir=/opt/mysql/etc \--localstatedir=/opt/mysql/data \--with-tcp-port=3306 \--with-unix-socket-path=/tmp/mysqld.sock \--with-mysqld-user=mysql \--enable-assembler \--with-extra-charsets=all \--enable-thread-safe-client \--with-big-tables \--with-readline \--with-ssl \--with-embedded-server \--enable-local-infile \--with-plugins=partition,innobase,myisammrg经过与cmake的参数对照之后,去除掉已经被取消的参数(大多数是因为新版本已经默认启用),cmake的参数配置如下:
cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql \-DSYSCONFDIR=/opt/mysql/etc \-DMYSQL_DATADIR=/opt/mysql/data \-DMYSQL_TCP_PORT=3306 \-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \-DMYSQL_USER=mysql \-DEXTRA_CHARSETS=all \-DWITH_READLINE=1 \-DWITH_SSL=system \-DWITH_EMBEDDED_SERVER=1 \-DENABLED_LOCAL_INFILE=1 \-DWITH_INNOBASE_STORAGE_ENGINE=15.编译安装 MySQL 5.5.x
通过http://www.mysql.com/downloads/mysql官方网址或国内的sohu镜像下载软件包,如目前最新的MySQL 5.5.13。# wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.13.tar.gz# tar zxvf mysql-5.5.13.tar.gz
# cd mysql-5.5.13
# cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql \-DSYSCONFDIR=/opt/mysql/etc \-DMYSQL_DATADIR=/opt/mysql/data \-DMYSQL_TCP_PORT=3306 \-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \-DMYSQL_USER=mysql \-DEXTRA_CHARSETS=all \-DWITH_READLINE=1 \-DWITH_SSL=system \-DWITH_EMBEDDED_SERVER=1 \-DENABLED_LOCAL_INFILE=1 \-DWITH_INNOBASE_STORAGE_ENGINE=1# make
# make install在make与make install的时候可以看到进度百分比,感觉这一点要比configure方式要好。
6.配置并初始化数据库
创建my.cnf配置文件# mkdir /opt/mysql/log# mkdir /opt/mysql/etc
# cp support-files/my-medium.cnf /opt/mysql/etc/my.cnf初始化数据库
执行前需赋给scripts/mysql_install_db文件执行权限# chmod 755 scripts/mysql_install_db# scripts/mysql_install_db --user=mysql --basedir=/opt/mysql/ --datadir=/opt/mysql/data/创建管理MySQL数据库的shell脚本
# mkdir /opt/mysql/init.d# cp support-files/mysql.server /opt/mysql/init.d/mysql赋予shell脚本可执行权限:
# chmod +x /opt/mysql/init.d/mysql启动MySQL:
# /opt/mysql/init.d/mysql start通过命令行登录管理MySQL服务器(提示输入密码时直接回车):
# /opt/mysql/bin/mysql -u root -p -S /tmp/mysql.sock输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';为root帐户设置初始密码
# /opt/mysql/bin/mysqladmin -u root password 'new-password'删除本机匿名连接的空密码帐号
/opt/mysql/bin/mysql -uroot -p'new-password'mysql>use mysql; //选择系统数据库mysqlmysql>select Host,User,Password from user; //查看所有用户mysql>delete from user where password="";mysql>flush privileges;mysql>select Host,User,Password from user; //确认密码为空的用户是否已全部删除mysql>exit;http://heylinux.com/archives/993.html
