1.MySQL安装方式选择
1.1 yum直接安装
安装非常简单,适合对MySQL没有什么要求时使用.
正常基本不考虑yum安装(开发本地装个客户端可以用),不能修改安装路径,导致一台服务器上只能安装一个MySQL,要安装新的需要先卸载
1.2 rpm包安装
可以选择MySQL版本进行下载. 与yum基本类似,不同只在于自己去下rpm安装包
同yum
1.2 二进制安装(免编译版)
安装简单(相对源码安装而言,不用定向编译),相当于源码编译出一个通用版,对MySQL系统有基本的控制力,至少可以同时存在多个MySQL版本
性能不如源码编译,因为源码编译可以定制编译参数,使得最后版本定向在某种环境或者某个操作系统而言有额外的运行效率提升.
1.3 源码安装
性能最高(统一的环境下),对MySQL系统干预力度最大(甚至可以自行分解组件等)
编辑参数配置复杂,编译时间长,
这里选择二进制安装,yum,rpm基本不考虑.也达不到需要定制编译来提高性能的程度
2.准备安装包
mysql-5.6.23-linux-glibc2.5-x86_64.tar
上传到服务器
3.安装
3.1安装到这里
#mkdir /usr/local
#mv /opt/software/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz /usr/local/
#cd /usr/local
3.2检查是否存在
#ps -ef|grep mysqld
#rpm -qa |grep -i mysql
3.3解压&&改名
#tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
#mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
3.4创建用户组
#groupadd -g 101 dba
3.5创建管理员
#useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
如果mysqladmin 已经存在#usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #
检查一下 #id mysqladmin
设置管理员密码#passwd mysqladmin
3.6 异步非阻塞接口组件
#yum -y install libaio
3.7配置单独环境变量
#cp /etc/skel/.* /usr/local/mysql
#vi /etc/my.cnf
覆盖以下内容

3.8环境配置文件提权
#chown mysqladmin:dba /etc/my.cnf
#chmod 640 /etc/my.cnf
检查一下#ll /etc/my.cnf
3.9变更独立环境配置文件给MySQL管理员
#chown -R mysqladmin:dba /usr/local/mysql
#chmod -R 755 /usr/local/mysql
4.MySQL初始化
4.1 切换到MySQL管理员账户
#su - mysqladmin
看看 #pwd
#mkdir arch
4.2 初始化
#scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
5.设置开机自启动
# cd /usr/local/mysql
服务文件拷贝到init.d下，并重命名为mysql # cp support-files/mysql.server /etc/rc.d/init.d/mysql
赋予可执行权限 # chmod +x /etc/rc.d/init.d/mysql
删除服务 # chkconfig --del mysql
添加服务 # chkconfig --add mysql
# chkconfig --level 345 mysql on
6.启动MySQL
还是切到MySQL管理员 # su - mysqladmin
# rm -rf my.cnf
# bin/mysqld_safe &
