  搭建服务器第一步:安装数据库

 我这里选择的是比较通用的mysql,满足大部分的市场需求了。

  首先准备好mysql压缩包Xshell和Xftp这里给个地址:https://pan.baidu.com/s/1DHZaroNWV78TYnob5kOTgg

1、在上面的链接下载tar包,或者使用wget从官网下载

  wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

2、将mysql安装到/usr/local/mysql下

  # 解压

  tar -xvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

  # 移动

  mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/

  # 重命名

  mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql

3、新建data目录

  mkdir /usr/local/mysql/data

4、新建mysql用户、mysql用户组

  # mysql用户组

  groupadd mysql

  # mysql用户

  useradd mysql -g mysql

5、将/usr/local/mysql的所有者及所属组改为mysql

  chown -R mysql.mysql /usr/local/mysql

6、配置

  /usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data

  # 如果出现以下错误:

2018-07-14 06:40:32 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-07-14 06:40:32 [ERROR]   Child process: /usr/local/mysql/bin/mysqldterminated prematurely with errno= 32
2018-07-14 06:40:32 [ERROR]   Failed to execute /usr/local/mysql/bin/mysqld --bootstrap --datadir=/usr/local/mysql/data --lc-messages-dir=/usr/local/mysql/share --lc-messages=en_US --basedir=/usr/local/mysql
-- server log begin --

-- server log end --

  # 则使用以下命令:

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

  # 如果出现以下错误:

/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

  # 则执行以下命令:

  yum -y install numactl

  # 完成后继续安装:

/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

  # 编辑/etc/my.cnf

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8
# 取消密码验证
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

  7、开启服务

  # 将mysql加入服务

  cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

  # 开机自启

  chkconfig mysql on

  # 开启

  service mysql start

  8、设置密码

  # 登录(由于/etc/my.cnf中设置了取消密码验证,所以此处密码任意)

  /usr/local/mysql/bin/mysql -u root -p

  # 操作mysql数据库

  >>use mysql;

  # 修改密码

  >>update user set authentication_string=password(‘你的密码‘) where user=‘root‘;

  >>flush privileges;

  >>exit;

  9、将/etc/my.cnf中的skip-grant-tables删除

  10、登录再次设置密码(不知道为啥如果不再次设置密码就操作不了数据库了)

  /usr/local/mysql/bin/mysql -u root -p

   >>ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘修改后的密码‘;

  >>exit;

  11、允许远程连接

  /usr/local/mysql/bin/mysql -u root -p

  >>use mysql;

  >>update user set host=‘%‘ where user = ‘root‘;

  >>flush privileges;

  >>eixt;

  12、添加快捷方式

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