mysql-5.5.37多实例的安装
CentOS 6.2下安装编译mysql-5.5.37 ##多实例 原理也是先安装单实例后面安装多实例
首先yum安装
yum install gcc gcc-c++ cmake ncurses-devel bison
1 单实例Mysql数据库的安装
1.1 建立mysql账号
[root@192 ~]# groupadd mysql
[root@192 ~]# useradd -s /sbin/nologin -g mysql -M mysql ##-M表示不创建家目录
创建完成之后查看下
[root@192 ~]# grep mysql /etc/passwd
mysql:x:500:500::/home/mysql:/sbin/nologin
1.2建立mysql的安装目录
[root@192 ~]# mkdir -p /usr/local/mysql
[root@192 ~]# mkdir -p /data/mysql/data
1.3下载mysql http://dev.mysql.com/downloads/ 或者去搜狐镜像源下载 然后上传到服务器
2；安装mysql
2,1检测系统原来是否有安装过mysql
[root@taoke1 ~]# rpm -qa |grep mysql
mysql-libs-5.1.61-1.el6_2.1.i686
这里是没有安装过mysql 如果有的话就需要先卸载mysql安装包 rpm -e --nodeps mysql.X.X.X
2,2安装编译mysql编译所需要的包
yum -y install make gcc-c++ cmake bison-devel ncurses-devel
如果前面安装过这些包的话可以分开查询下再安装
2,3解压mysql并安装
[root@taoke1 ~]# tar xzvf mysql-5.5.37.tar.gz
[root@taoke1 ~]# cd mysql-5.5.37
cmake \
-DMYSQL_USER=mysql \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/data/mysql/data \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \

-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ #套接字文件
[root@taoke1 mysql-5.6.23]# make && make install
3；初始化数据库
[root@xiangys02 mysql]# mkdir -p /data/mysql/data/{3306,3307} ##建立两个实例
/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data/3306 --user=mysql
/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data/3307 --user=mysql
