vue项目部署上线遇到的问题及解决方法

mkdir /usr/local //进入此目录 
wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz //下载mysql压缩包
tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz //解压
mv mysql-5.7.11-Linux-glibc2.5-x86_64/ mysql //重命名,方便后面的设置groups mysql //查看是否有mysql用户组,有就跳过(mysql:mysql) 没有就创建(groups:mysql: No such user) 括号里为判断信息groupadd mysql useradd -r -g mysql mysql //创建用户组cd mysql/ chown -R mysql:mysql ./ //修改权限
mkdir /usr/local/mysql/data //创建data目录
./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ //初始化信息 这里可能报错一个模块找不到,直接yum安装              就行了
[root@localhost mysql] ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

cp -a ./support-files/my-default.cnf /etc/my.cnf //复制文件
cp -a ./support-files/mysql.server /etc/init.d/mysqld
修改my.cnf文件

ln -s /usr/local/mysql/ /usr/bin/ //创建In

[root@localhost ~]# mysql -u root -p //登录数据库
alter user root@localhost identified by 'tiger'; //修改数据库密码(有的时候修改成功了,远程的时候还是不可以.远程管理工具比如dbvisualizer报错28000 
       那么就在修改一次数据库密码)
flush privileges; //刷新
show databases;//显示数据库。

 在shell6连接到mysql 数据库
 use mysql //选择mysql 数据库
