rocky9 安装mysql

基于二进制方式

系统信息：

$ cat /etc/system-release
Rocky Linux release 9.0 (Blue Onyx)

1. 准备安装包：

https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz

2. 解压

$ tar zxvf mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz -C /usr/local

3. 创建用户授权

$ useradd mysql
$ mv /usr/local/mysql-5.7.38-linux-glibc2.12-x86_64 /usr/local/mysql
$ chown mysql:mysql -R /usr/local/mysql
$ echo "export PATH=\$PATH:/usr/local/mysql/bin" >> ~/.bash_profile
$ source ~/.bash_profile

4. 创建配置文件

$ tee /etc/my.cnf <

5. 创建所需目录

$ mkdir -p /var/run/mysqld
$ chown mysql:mysql /var/run/mysqld
$ touch /var/log/mysqld.log /var/log/slow-query.log
$ chown mysql:mysql /var/log/mysqld.log
$ chown mysql:mysql /var/log/slow-query.log

6. 创建service

$ tee /usr/lib/systemd/system/mysqld.service <

7. 初始化数据

$ /usr/local/mysql/bin/mysql_install_db --user=mysql --datadir=/var/lib/mysql

8. 启动mysql

$ systemctl enable --now mysqld

9. 查看状态

$ systemctl status mysqld

10. 建立动态库链接

$ ln -s /usr/lib64/libncurses.so.6 /usr/lib64/libncurses.so.5
$ ln -s /usr/lib64/libtinfo.so.6 /usr/lib64/libtinfo.so.5

11. 初始化root口令测试

$ systemctl stop mysqld
$ mysqld_safe --skip-grant-tables &
$ mysql -u root
