概述:
CentOS 6.4下通过yum安装的MySQL是5.1版的,比较老,所以就想通过源代码安装高版本的5.6.14。
正文:
一:卸载旧版本
使用下面的命令检查是否安装有MySQL Server
rpm -qa | grep mysql
有的话通过下面的命令来卸载掉
rpm -e mysql //普通删除模式 rpm -e --nodeps mysql // 强力删除模式,如果使用上面命令删除时,提示有依赖的其它文件,则用该命令可以对其进行强力删除
二:安装MySQL
安装编译代码需要的包
yum -y install make gcc-c++ cmake bison-devel ncurses-devel
下载MySQL 5.6.14
wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.14.tar.gz tar xvf mysql-5.6.14.tar.gz cd mysql-5.6.14
编译安装
cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DSYSCONFDIR=/etc \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci make && make install
编译的参数可以参考http://dev.mysql.com/doc/refman/5.5/en/source-configuration-options.html。
整个过程需要30分钟左右……漫长的等待
三:配置MySQL
设置权限
使用下面的命令查看是否有mysql用户及用户组
cat /etc/passwd 查看用户列表 cat /etc/group 查看用户组列表
如果没有就创建
groupadd mysql useradd -g mysql mysql
修改/usr/local/mysql权限
chown -R mysql:mysql /usr/local/mysql
修改/usr/local/mysql权限
初始化配置
进入安装路径
cd /usr/local/mysql
进入安装路径,执行初始化配置脚本,创建系统自带的数据库和表
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
注:在启动MySQL服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到则会搜索"$basedir/my.cnf",在本例中就是 /usr/local/mysql/my.cnf,这是新版MySQL的配置文件的默认位置!注意:在CentOS 6.4版操作系统的最小安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字,如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。
启动MySQL
添加服务,拷贝服务脚本到init.d目录,并设置开机启动
cp support-files/mysql.server /etc/init.d/mysql chkconfig mysql on service mysql start --启动MySQL
配置用户
MySQL启动成功后,root默认没有密码,我们需要设置root密码。
设置之前,我们需要先设置PATH,要不不能直接调用mysql
修改/etc/profile文件,在文件末尾添加
PATH=/usr/local/mysql/bin:$PATH export PATH
关闭文件,运行下面的命令,让配置立即生效
<span>source /etc/profile</span>
现在,我们可以在终端内直接输入mysql进入,mysql的环境了
执行下面的命令修改root密码
mysql -uroot mysql> SET PASSWORD = PASSWORD('123456');
若要设置root用户可以远程访问,执行
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%' IDENTIFIED BY '<span>password</span>' WITH GRANT OPTION;
红色的password为远程访问时,root用户的密码,可以和本地不同。
配置防火墙
防火墙的3306端口默认没有开启,若要远程访问,需要开启这个端口
打开/etc/sysconfig/iptables
在“-A INPUT –m state --state NEW –m tcp –p –dport 22 –j ACCEPT”,下添加:
-A INPUT m state --state NEW m tcp p dport 3306 j ACCEPT
然后保存,并关闭该文件,在终端内运行下面的命令,刷新防火墙配置:
service iptables restart
OK,一切配置完毕,你可以访问你的MySQL了~
