CentOS6.8手动安装MySQL5.6
CentOS6.8手动安装MySQL5.6
yum install perl libaio
众所周知,mysql5.7推出后有很多没有填好的坑,对于老的系统和项目兼容性也存在问题,所以现在普遍的web项目还是应该跑在centos6.8+mysql5.6的环境之下,今天主要说一下mysql5.6如何编译安装的具体步骤。
1.安装mysql5.6依存包
2.下载编译包
wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gztar xvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
3.复制到指定目录
mv mysql-5.6.35-linux-glibc2.5-x86_64 /usr/local/mysql
4.创建mysql用户和组
groupadd mysql useradd -r -g mysql mysql -d /usr/local/mysqlpasswd mysql
5.修改目录权限
chown -R mysql:mysql /usr/local/mysql
6.安装数据库
su mysql/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data exit
7.复制mysql配置文件
cd /usr/local/mysql/support-filescp my-default.cnf /etc/my.cnf
8.添加系统服务
cp mysql.server /etc/init.d/mysql chkconfig mysql on
9.添加环境变量
vim /etc/profile
在最下面添加
export MYSQL_HOME="/usr/local/mysql"export PATH="$PATH:$MYSQL_HOME/bin"
保存退出后,执行生效代码
. /etc/profile
10.启动mysql
service mysql start
11.设置root密码
mysqladmin -u root password '123456'
12.设置默认端口
vim /etc/my.cnf
[mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql/data port=3306server_id=1socket=/tmp/mysql.sock
13.允许所有外部链接访问(可选)
mysql -u root -p
mysql命令行输入
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; FLUSH PRIVILEGES;
