MYSQL三种安装方式--rpm包安装

1. 首先检查机器里是否已经存在MySQL 

$ rpm -qa |  grep mysql

2. 去官网下载相应的rpm包：https://dev.mysql.com/downloads/mysql/

mysql-community-common-5.7.19-1.el6.x86_64.rpm
mysql-community-client-5.7.19-1.el6.x86_64.rpm
mysql-community-server-5.7.19-1.el6.x86_64.rpm
mysql-community-libs-5.7.19-1.el6.x86_64.rpm

3. 上传到/usr/local/src文件夹，进行安装mysql

 

# 按照以下顺序进行安装，因为它们之间存在依赖关系
common --> libs --> clients --> server

　　

$ rpm -ivh mysql-community-common-5.7.19-1.el6.x86_64.rpm

$ rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm

$ rpm -ivh mysql-community-clients-5.7.19-1.el6.x86_64.rpm

$ rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rpm

 

！！！这里出现的错误

# error: Failed dependencies: \
        libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.19-1.el6.x86_64 \
        libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.19-1.el6.x86_64 \
        libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.19-1.el6.x86_64 

解决方法：

$ yum install -y numactl

 

4. 安装好后，可以去检查是否存在MySQL的配置文件或者MySQL的命令在/usr/bin下

#mysql配置文件
$ ls /etc/my.cnf

# mysql命令
$ cd /usr/bin/
$ ls | grep mysql

　　

$ /etc/init.d/mysqld start
$ ps aux|grep mysqld
