CentOS7.4下MySQL5.7.28二进制方式安装的方法步骤
这篇文章主要介绍了CentOS7.4下MySQL5.7.28二进制方式安装的方法步骤,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
Linux系统版本:CentOS7.4
MySQL版本:5.7.28
在Linux平台有RPM包、二进制包、源码包3中安装方式,这一篇文章主要是以RPM包为例来介绍如何在Linux平台下进行MySQL的安装。
下载地址:
https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz
具体安装步骤如下:
(1)首先卸载mariadb,不然后面会和安装mysql需要的库冲突:
1 2 3 | [root@localhost ~] # rpm -qa | grep mariadb mariadb-libs-5.5.56-2.el7.x86_64 [root@localhost ~] # rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64 |
(2)用root用户登录系统,增加mysql用户和组,数据库安装在此用户下:
1 2 | [root@localhost ~] # groupadd mysql [root@localhost ~] # useradd -r -g mysql -s /bin/false mysql |
(3)准备数据目录
以/app/data为例,建议使用逻辑卷
1 2 3 | [root@localhost ~] # mkdir -p /app/data [root@localhost ~] # chown mysql.mysql /app/data/ [root@localhost ~] # chmod 750 /app/data |
(4)准备二进制文件:
1 2 3 4 | [root@localhost ~] # tar xvf mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ root@localhost ~] # cd /usr/local [root@localhost local ] # ln -sv mysql-5.7.28-linux-glibc2.12-x86_64 mysql ‘mysql ' -> ‘mysql-5.7.28-linux-glibc2.12-x86_64' |
(5)初始化MySQL:
1 2 3 4 5 6 7 8 9 | [root@localhost ~] # cd /usr/local/mysql [root@localhost mysql] # bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/app/data 2019-11-03T09:47:18.263716Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2019-11-03T09:47:19.059462Z 0 [Warning] InnoDB: New log files created, LSN=45790 2019-11-03T09:47:19.140866Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2019-11-03T09:47:19.207569Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: ed1cd8ec-fe1e-11e9-8c9c-000c29f8617a. 2019-11-03T09:47:19.209181Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2019-11-03T09:47:19.646366Z 0 [Warning] CA certificate ca.pem is self signed. 2019-11-03T09:47:20.056792Z 1 [Note] A temporary password is generated for root@localhost: rY-6f?? #!<zO |
其中--basedir mysql基础目录 --datadir mysql数据存放目录,并创建了root用户的临时密码:rY-6f??#!<zO
(6)开启ssl连接:
1 2 3 | [root@localhost mysql] # bin/mysql_ssl_rsa_setup 2019-11-03 23:09:55 [ERROR] Failed to access directory pointed by --datadir. Please make sure that directory exists and is accessible by mysql_ssl_rsa_setup. Supplied value : /usr/local/mysql/data [root@localhost mysql] # bin/mysql_ssl_rsa_setup --datadir=/app/data |
命令后面不加参数报错,加了--datadir后不报错
(7)编辑配置文件,保存退出:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | [root@localhost mysql] # vim /etc/my.cnf [mysqld] # GENERAL datadir= /app/data socket= /app/data/mysql .sock user=mysql default-storage-engine=InnoDB [mysqld_safe] log-error= /app/data/mysql-error .log pid- file = /app/data/mysqld .pid [client] socket= /app/data/mysql .sock |
(8)启动MySQL:
1 | [root@localhost mysql] # bin/mysqld_safe --user=mysql & |
(9)配置环境变量:
1 2 3 4 | [root@localhost ~] # vim /etc/profile #添加下面一行 export PATH=$PATH: /usr/local/mysql/bin [root@localhost ~] # source /etc/profile |
(10)设置开机启动:
1 2 | [root@localhost mysql] # cp support-files/mysql.server /etc/init.d/mysql.server [root@localhost mysql] # chkconfig --add mysql.server |
(11)测试登录成功:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | [root@localhost ~] # mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
