MySQL安装
安装MySQL版本为5.7，Linux CentOS6系统
前往官网https://dev.mysql.com/downloads/mysql/5.7.html#downloads下载RPM Bundle
上传到服务器上，tar解压:
[root@server0 sh]# tar -xvf mysql-5.7.24-1.el6.x86_64.rpm-bundle.tar [root@server0 sh]# ls *.rpm mysql-community-client-5.7.24-1.el6.x86_64.rpm mysql-community-common-5.7.24-1.el6.x86_64.rpm mysql-community-devel-5.7.24-1.el6.x86_64.rpm mysql-community-embedded-5.7.24-1.el6.x86_64.rpm mysql-community-embedded-devel-5.7.24-1.el6.x86_64.rpm mysql-community-libs-5.7.24-1.el6.x86_64.rpm mysql-community-libs-compat-5.7.24-1.el6.x86_64.rpm mysql-community-server-5.7.24-1.el6.x86_64.rpm mysql-community-test-5.7.24-1.el6.x86_64.rpm
其中：
mysql-community-server-5.7.24-1.el6.x86_64.rpm 主程序包，提供服务的主包
mysql-community-client-5.7.24-1.el6.x86_64.rpm 管理工具数据库
剩下的都是辅助功能软件包，开始安装MySQL5.7：
[root@server0 sh]# rpm -Uvh mysql-community-*.rpm #升级安装mysql，发现依赖包 warning: mysql-community-client-5.7.24-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY error: Failed dependencies: libnuma.so.1()(64bit) is needed by mysql-community-embedded-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-embedded-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-embedded-5.7.24-1.el6.x86_64 libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.24-1.el6.x86_64 libnuma.so.1()(64bit) is needed by mysql-community-test-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-test-5.7.24-1.el6.x86_64 libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-test-5.7.24-1.el6.x86_64 perl(JSON) is needed by mysql-community-test-5.7.24-1.el6.x86_64 perl(Time::HiRes) is needed by mysql-community-test-5.7.24-1.el6.x86_64 [root@server0 sh]# yum -y install libnuma.so.1* #安装依赖包 [root@server0 sh]# yum -y install perl-JSON #安装依赖包 [root@server0 sh]# yum -y install perl-Time-HiRes #安装依赖包 [root@server0 sh]# rpm -Uvh mysql-community-*.rpm #再次执行，成功安装
[root@server0 sh]# rpm -qa | grep -i mysql #查询MySQL是否安装成功 mysql-community-common-5.7.24-1.el6.x86_64 mysql-community-devel-5.7.24-1.el6.x86_64 mysql-community-libs-compat-5.7.24-1.el6.x86_64 mysql-community-libs-5.7.24-1.el6.x86_64 mysql-community-server-5.7.24-1.el6.x86_64 mysql-community-embedded-5.7.24-1.el6.x86_64 mysql-community-test-5.7.24-1.el6.x86_64 mysql-community-client-5.7.24-1.el6.x86_64 mysql-community-embedded-devel-5.7.24-1.el6.x86_64
首次安装完成后mysql会自动创建/var/lib/mysql数据库目录，数据库目录/var/lib/mysql下是没有任何文件的，首次启动数据库的时候会数据初始化，初始化成功后在数据库目录/var/lib/mysql下自动生成文件，每次启动或重启数据库时会加载数据库目录下的文件，如果数据库目录下文件丢失那么会导致服务起不来！
[root@server0 mysql]# service mysqld start #启动mysql 初始化 MySQL 数据库： [确定] 正在启动 mysqld： [确定]
[root@server0 mysql]# service mysqld status #查询服务状态 mysqld (pid 7745) 正在运行...
[root@server0 mysql]# pwd;ls; /var/lib/mysql auto.cnf client-key.pem ib_logfile1 mysql.sock.lock server-cert.pem ca-key.pem ib_buffer_pool ibtmp1 performance_schema server-key.pem ca.pem ibdata1 mysql private_key.pem sys client-cert.pem ib_logfile0 mysql.sock public_key.pem
[root@server0 mysql]# chkconfig mysqld on #设置mysql为开启自启动 [root@server0 mysql]# chkconfig mysqld --list mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
mysql服务相关参数
主配置文件：/etc/my.cnf
数据库目录：/var/lib/mysql（自动创建）
默认端口号：3306
进程名：mysqld
传输协议：TCP
进程所有者：mysql
进程所属组：mysql
使用RPM安装方式会自动创建用户mysql，组mysql，数据库目录的属主组都是mysql，因为要对数据库目录进行读写；
[root@server0 ~]# ls -ld /var/lib/mysql
drwxr-x--x. 5 mysql mysql 4096 12月 4 23:21 /var/lib/mysql
总结：
1、解压
[root@server0 sh]# tar -xvf mysql-5.7.24-1.el6.x86_64.rpm-bundle.tar
2、装包，并且安装依赖包
[root@server0 sh]# rpm -Uvh mysql-community-*.rpm
[root@server0 sh]# yum -y install libnuma.so.1*
[root@server0 sh]# yum -y install perl-JSON
[root@server0 sh]# yum -y install perl-Time-HiRes
[root@server0 sh]# rpm -Uvh mysql-community-*.rpm
3、启服务
[root@server0 mysql]# service mysqld start
4、开机自启
[root@server0 mysql]# chkconfig mysqld on
