本文实例为大家分享CentOS 7.2 Yum安装mysql5.6的方法,供大家参考,具体内容如下
配置CentOS SCLo源
[3] 添加 CentOS SCLo Software collections Repository. [root@linuxprobe~]# yum -y install centos-release-scl-rh centos-release-scl # set [priority=10] [root@linuxprobe~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo [root@linuxprobe~]# sed -i -e "s/\]$/\]\npriority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo # for another way, change to [enabled=0] and use it only when needed [root@linuxprobe~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo [root@dlp ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo
yum安装MySQL
# 安装mysql [root@linuxprobe~]# yum --enablerepo=centos-sclo-rh -y install rh-mysql56-mysql-server # 加载环境变量 [root@linuxprobe ~]# scl enable rh-mysql56 bash [root@linuxprobe ~]# mysql -V mysql Ver 14.14 Distrib 5.6.26, for Linux (x86_64) using EditLine wrapper [root@linuxprobe ~]# which mysql /opt/rh/rh-mysql56/root/usr/bin/mysql # 设置mysql开机自启动 root@linuxprobe ~]# vi /etc/profile.d/rh-mysql56.sh #!/bin/bash source /opt/rh/rh-mysql56/enable export X_SCLS="`scl enable rh-mysql56 'echo $X_SCLS'`"
[4] Enable MySQL 5.6 and Configure initial settings. [root@linuxprobe ~]# vi /etc/opt/rh/rh-mysql56/my.cnf.d/mysql-server.cnf # add follows within [mysqld] section [mysqld] character-set-server=utf8 [root@linuxprobe ~]# systemctl start rh-mysql56-mysqld [root@linuxprobe ~]# systemctl enable rh-mysql56-mysqld [root@linuxprobe ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. # set root password Set root password"htmlcode">[root@linuxprobe ~]# mysql -u root -p Enter password: Welcome to the MySQL monitor.

[root@linuxprobe ~]# firewall-cmd –add-service=MySQL –permanent success [root@linuxprobe ~]# firewall-cmd –reload success同样使用yum在vdevops.org上面安装mysql,安装步骤参考上面
