下面 启动服务器
systemctl start mysqld
登录MySQL
# 获取初始化密码
[root@localhost opt]# cat /var/log/mysqld.log | grep password
# 登录
[root@localhost opt]# mysql -u root -p# 修改密码
mysql> ALTER USER USER() IDENTIFIED BY 'Abc123-S';
# 退出
mysql> exit;
Bye
因为root账户只能本地登录，所以我们给他新建用户
mysql> CREATE USER 'tom'@'%' IDENTIFIED BY 'Abc123-S';
Query OK, 0 rows affected (0.01 sec)mysql> GRANT ALL ON *.* TO 'tom'@'%';
Query OK, 0 rows affected (0.00 sec)
开启防火墙端口
firewall-cmd --zone=public --add-port=3306/tcp --permanentsystemctl restart firewalld
Navicat连接
安装Redis
解压到当前文件夹
tar -xvf redis-6.0.6.tar.gz
安装gcc（因为centos默认安装4.8.5版本的，不满足需要）
yum install centos-release-scl
yum install devtoolset-8-gcc*
echo "source /opt/rh/devtoolset-8/enable" >>/etc/profile
source /etc/profile
# 查看版本
gcc -v
gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)
进入redis目录
cd redis-6.0.6/
执行make命令
make MALLOC=libc/jemalloc
然后install
make install
这个默认在/usr/local/bin目录生成服务器文件
修改redis配置文件
vi /opt/redis-6.0.6/redis.conf
bind 192.168.28.128
daemonize yes
绑定地址，以及后台启动
启动
./redis-server /opt/redis-6.0.6/redis.conf
本地连接测试
