The Tenth Week (Lucklyzpp)

1、通过编译、二进制安装MySQL5.7

root@Lucklyzpp ~]# ls
anaconda-ks.cfg  a.txt  mysql-5.7.35-linux-glibc2.12-x86_64.tar
[root@Lucklyzpp ~]# yum  -y install libaio numactl-libs
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
软件包 libaio-0.3.109-13.el7.x86_64 已安装并且是最新版本
软件包 numactl-libs-2.0.12-5.el7.x86_64 已安装并且是最新版本
无须任何处理
[root@Lucklyzpp ~]# groupadd mysql
[root@Lucklyzpp ~]# useradd -r -g mysql -s /bin/false mysql

2、二进制安装mariadb10.4

#mysql用户组和用户的创建
groupadd -r mysql
useradd -r -g mysql -s /sbin/nologin mysql

#压缩包解压到指定目录
tar xvf mariadb-10.5.5-linux-x86_64.tar.gz -C /usr/local

#进入解压缩目录
cd /usr/local

#建立软连接并更改权限
ln -s mariadb-10.5.5-linux-x86_64/ mysql
chown -R root.root /usr/local/mysql/

#准备配置文件
vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
skip_name_resolve=1
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid

[client]
socket=/data/mysql/mysql.sock

[mysql]
auto-rehash
prompt="\u@\h [\d]>"

#进入mysql目录
cd mysql

#数据库文件初始化
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql


#环境变量设置
方法1   echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
        . /etc/profile.d/mysql.sh

方法2   ln -s /usr/local/mysql/bin/* /usr/local/bin/

#准备服务脚本
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

#启动mysql
chkconfig --add mysqld
service mysqld start

#修改root登录口令
mysqladmin -uroot password zhengpengpeng@1

#登录mysql
mysql -uroot -pzhengpengpeng@1
