二进制包安装MySQL5.7.29

还是5.7.29，还是CentOS 7

二进制包安装MySQL

一、下载

1. 安装依赖包

   yum install ncurses-devel.x86_64 libaio.x86_64 -y
   

2. 下载MySQL二进制包

   方法一：使用wget命令直接下载

   wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.29-el7-x86_64.tar.gz
   

   方法二：到官网下载，然后上传到Linux

   https://downloads.mysql.com/archives/community/

   选择对应的版本

   

   

3. 解压缩

   # 解压缩
   tar xf mysql-5.7.29-el7-x86_64.tar
   tar -zxf mysql-5.7.29-el7-x86_64.tar.gz
   
   # 移动到/usr/local下
   mv mysql-5.7.29-el7-x86_64 /usr/local/mysql
   

二、修改配置文件并初始化

1. 前提工作

   # 创建mysql用户
   useradd -r -s /sbin/nologin mysql
   
   # 建立工作目录
   mkdir -p /data/mysql/{data,log}
   
   # 授权目录
   chown -R mysql.mysql /data/mysql
   chown -R mysql.mysql /usr/local/mysql
   

2. 编辑配置文件

   cat > /etc/my.cnf << EOF
   [client]
   default-character-set = utf8mb4
   port = 3306
   socket = /data/mysql/mysql.sock
   
   [mysqld]
   server_id = 1
   character-set-server = utf8
   user = mysql
   port = 3306
   socket = /data/mysql/mysql.sock
   basedir = /usr/local/mysql
   datadir = /data/mysql/data
   log-error = /data/mysql/log/mysql_error.log
   log-bin = /data/mysql/log/mysql-bin
   binlog_format = ROW
   pid-file = /data/mysql/mysql.pid
   open_files_limit = 8192
   innodb_buffer_pool_size = 512M
   
   [mysql]
   auto-rehash
   prompt = '\u@\h [\d]> '
   EOF
   

3. 初始化

   /usr/local/mysql/bin/mysqld --initialize  --user=mysql --basedir=/usr/local/mysql/  --datadir=/data/mysql/data/
   

三、启动MySQL

1. 添加环境变量

   echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
   source /etc/profile
   

2. 启动

   cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
   /etc/init.d/mysql start
   chkconfig --add mysql
   

3. 获取默认密码登录

   # 获取默认密码
   temp_passwd=`cat /data/mysql/log/mysql_error.log | grep "temporary password" | awk '{print $NF}'`
   
   # 使用默认密码登录
   mysql -uroot -p$temp_passwd
   
   # 修改密码
   root@localhost [(none)]> ALTER USER 'root'@'localhost' IDENTIFIED BY 'NewPassword2233$';
   

二进制包安装mysql完成！
