# CentOS 8.2 安装 MySQL 5.7.39
|
||||
|
||||
## 检查系统是否自带MySQL
|
||||
|
||||
::: warning 笔者说
|
||||
检查系统中是否已经安装了 MySQL 或 MariaDB ,如果已经安装了,那就必须提前卸载掉它们,否则它们占用的端口号、服务名或是一些其他配置很可能会干扰到后续我们要安装的 MySQL 版本。
|
||||
|
||||
以前笔者就遇到过几次由这个情况引发的问题,要么是 MySQL 无法安装成功,要么是 MySQL 安装成功后输入正确密码却登录不进去。
|
||||
:::
|
||||
|
||||
```shell
|
||||
rpm -qa | grep mysql
|
||||
rpm -qa | grep mariadb
|
||||
# 如果上方两条命令查询出了内容,就把查出的软件卸载掉
|
||||
rpm -e --nodeps 软件名
|
||||
```
|
||||
|
||||
## 安装依赖
|
||||
|
||||
::: warning 笔者说
|
||||
和在 Windows 系统中一样,Linux 系统中安装程序也需要准备好所需的运行库。
|
||||
|
||||
不确认安装好它们,那在安装 MySQL 时就会出现这样那样的依赖报错,像下面这段报错就是由于没有安装好 `libaio` 库引起的。
|
||||
|
||||
>/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
|
||||
:::
|
||||
|
||||
```shell
|
||||
yum -y install numactl
|
||||
yum -y install libncurses*
|
||||
yum -y install libaio
|
||||
```
|
||||
|
||||
## 下载并上传安装包
|
||||
|
||||
可前往 [官网](https://downloads.mysql.com/archives/community) 下载 MySQL 安装包然后上传到服务器。也可以直接在服务器内下载。
|
||||
|
||||
```shell
|
||||
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.39-linux-glibc2.12-x86_64.tar.gz
|
||||
```
|
||||
|
||||
## 解压安装包
|
||||
|
||||
::: warning 笔者说
|
||||
除去一些固定的东西,一定要记得根据你实际的情况调整好目录位置或命名。
|
||||
:::
|
||||
|
||||
```shell
|
||||
# 解压安装包到指定目录(如指定目录不存在则需要先提前用 mkdir 创建)
|
||||
# 下方 /opt/disk 是服务器的一块数据盘挂载目录
|
||||
tar -zxvf mysql-5.7.39-linux-glibc2.12-x86_64.tar.gz -C /opt/disk
|
||||
|
||||
# 重命名目录
|
||||
mv mysql-5.7.39-linux-glibc2.12-x86_64 mysql
|
||||
|
||||
# 创建 MySQL 数据存储目录
|
||||
cd mysql
|
||||
mkdir data
|
||||
```
|
||||
|
||||
## 创建mysql用户组和mysql用户
|
||||
|
||||
```shell
|
||||
# 创建 mysql 用户组
|
||||
groupadd mysql
|
||||
|
||||
# 创建 mysql 用户
|
||||
useradd -r -g mysql mysql
|
||||
|
||||
# 将 MySQL 安装目录授权给 mysql 用户组的 mysql 用户
|
||||
chown -R mysql:mysql ./
|
||||
```
|
||||
|
||||
## 创建配置文件
|
||||
|
||||
创建 my_default.cnf 配置文件。
|
||||
|
||||
```shell
|
||||
vim /opt/disk/mysql/support-files/my_default.cnf
|
||||
```
|
||||
|
||||
将下方内容插入到配置文件中,保存并退出编辑。
|
||||
|
||||
::: tip 笔者说
|
||||
下方的配置中,指定了 MySQL 安装目录、MySQL 数据存储目录、MySQL 服务占用端口、MySQL 默认字符集、MySQL 日志文件位置、MySQL 进程文件位置等。
|
||||
|
||||
**一定记得根据你实际的情况调整好。**
|
||||
:::
|
||||
|
||||
```shell
|
||||
[mysqld]
|
||||
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
|
||||
|
||||
basedir = /opt/disk/mysql
|
||||
datadir = /opt/disk/mysql/data
|
||||
port = 3306
|
||||
socket = /tmp/mysql.sock
|
||||
character-set-server=utf8
|
||||
|
||||
log-error = /opt/disk/mysql/data/mysqld.log
|
||||
pid-file = /opt/disk/mysql/data/mysqld.pid
|
||||
```
|
||||
|
||||
拷贝一份配置文件到 /etc 目录下,命名为 `my.cnf`。
|
||||
|
||||
```shell
|
||||
cp support-files/my_default.cnf /etc/my.cnf
|
||||
```
|
||||
|
||||
## 安装并启动MySQL服务
|
||||
|
||||
使用 `mysqld` 命令来安装 MySQL 服务,并指定好用户名、MySQL 安装目录、MySQL 数据存储目录。
|
||||
|
||||
```shell
|
||||
bin/mysqld --initialize --user=mysql --basedir=/opt/disk/mysql/ --datadir=/opt/disk/mysql/data/
|
||||
```
|
||||
|
||||
拷贝一份 MySQL 服务脚本到 `/etc/init.d` 目录下,命名为 `mysql`。
|
||||
|
||||
```shell
|
||||
cp support-files/mysql.server /etc/init.d/mysql
|
||||
```
|
||||
|
||||
启动 MySQL 服务。
|
||||
|
||||
```shell
|
||||
systemctl start mysql
|
||||
```
|
||||
|
||||
配置 MySQL 开机自启动。
|
||||
|
||||
```shell
|
||||
systemctl enable mysql
|
||||
```
|
||||
到此,MySQL 服务就安装完成了。但别着急,还需要做些配置才能真正用起来。
|
||||
|
||||
## 设置环境变量
|
||||
|
||||
::: tip 笔者说
|
||||
配置好环境变量,我们才能方便的在任何目录下使用 MySQL 的命令。
|
||||
:::
|
||||
|
||||
```shell
|
||||
# 1、打开 profile 文件
|
||||
vim /etc/profile
|
||||
|
||||
# 2、在其中插入环境变量配置
|
||||
MYSQL_HOME=/opt/disk/mysql
|
||||
PATH=$MYSQL_HOME/bin:$PATH
|
||||
export MYSQL_HOME PATH
|
||||
|
||||
# 3、重新加载 profile 文件,使最新配置生效
|
||||
source /etc/profile
|
||||
```
|
||||
|
||||
## 登录并修改密码
|
||||
|
||||
第一次登录时,首先从日志文件中找到随机生成的密码。
|
||||
|
||||
```shell
|
||||
cat /opt/disk/mysql/data/mysqld.log
|
||||
```
|
||||
|
||||
在日志文件中找到类似于下方输出的位置,其中 `8QE2NEqhB:ks` 就是密码。
|
||||
|
||||
```
|
||||
[Note] A temporary password is generated for root@localhost: 8QE2NEqhB:ks
|
||||
```
|
||||
|
||||
登录到 MySQL 服务端。
|
||||
|
||||
::: warning 笔者说
|
||||
有些时候随机生成的密码包含特殊符号,例如:`&`、`/`、`.`(你没看错,有时候最后有个 `.` 可千万别当作是句子结尾。
|
||||
|
||||
这种密码你在登录的时候,记得用 `'` 单引号给它引起来。
|
||||
|
||||
例如:`mysql -uroot -p'7AB5CDadE&'`
|
||||
:::
|
||||
|
||||
```shell
|
||||
mysql -uroot -p刚才从日志中找到的随机密码
|
||||
```
|
||||
|
||||
修改密码。
|
||||
|
||||
```shell
|
||||
set password = password('新密码');
|
||||
```
|
||||
|
||||
## 创建用户并授权
|
||||
|
||||
这一步就要根据你的实际个人需要来操作了。
|
||||
|
||||
```shell
|
||||
grant all on *.* to root@'%' identified by '你的密码';
|
||||
```
