一、软件安装 1. 安装必要的软件依赖
yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
2、下载 mysql 源码包
mkdir /software
cd /software
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26.tar.gz
查看下载包:
[root@localhost software]# ls
mysql-5.7.26.tar.gz
3、解压 mysql 源码包
tar -zxvf mysql-5.7.26.tar.gz
3、配置编译 mysql 源码包
进入解压后的目录,为了保持源码干净,新建子目录 yunxiaochong,在子目录下编译
[root@localhost software]# ls
mysql-5.7.26 mysql-5.7.26.tar.gz
[root@localhost software]# cd mysql-5.7.26/
[root@localhost mysql-5.7.26]# mkdir yunxiaochong
[root@localhost mysql-5.7.26]# cd yunxiaochong/
cmake 配置:
cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_SSL=bundled \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/tmp
注:
如果编译出现错误,请先删除 CMakeCache.txt 后,再重新编译:
rm -rf CMakeCache.txt
如果出现下面的提示就表示成功生成了编译环境:
— Configuring done
— Generating done
编译:
make -j 10
安装:
make instal
二、数据库安装 1、创建用户
1
2
groupadd mysql
useradd -g mysql mysql
2、创建目录,并修改目录属主和添加环境变量
mkdir -p /data/mysql/{3306,3307}/{data,log}
chown -R mysql:mysql /data/mysql/
chown -R mysql:mysql /usr/local/mysql/
echo export PATH=$PATH:/usr/local/mysql/bin /etc/profile
source /etc/profile
3、创建配置文件
3306
vim /data/mysql/3306/my3306.cnf
内容如下:
[mysqld]
basedir=/usr/local/mysql
datadir=/data/mysql/3306/data
port=3306
socket=/data/mysql/3306/mysql3306.sock
character-set-server=utf8
log-error=/data/mysql/3306/log/error3306.log
pid-file=/data/mysql/3306/mysqld3306.pid
3307
vim /data/mysql/3307/my3307.cnf
内容如下:
[mysqld]
basedir=/usr/local/mysql
datadir=/data/mysql/3307/data
port=3307
socket=/data/mysql/3307/mysql3307.sock
character-set-server=utf8
log-error=/data/mysql/3307/log/error3307.log
pid-file=/data/mysql/3307/mysqld3307.pid
4、数据库初始化
(1)3306
1
mysqld –defaults-file=/data/mysql/3306/my3306.cnf –initialize –user=mysql
(2)3307
1
mysqld –defaults-file=/data/mysql/3307/my3307.cnf –initialize –user=mysql
5、数据库启动
(1)3306
cd /usr/local/mysql/bin
./mysqld_safe --defaults-file=/data/mysql/3306/my3306.cnf --user=mysql
(2)3307
cd /usr/local/mysql/bin
./mysqld_safe --defaults-file=/data/mysql/3307/my3307.cnf --user=mysql
6、获取初始密码 [root@localhost bin]# less /data/mysql/3307/log/error3307.log|grep A temporary password
2019-07-22T02:04:41.482707Z 1 [Note] A temporary password is generated for root@localhost:
Kjipuugr0:0v
登录报错:
[mysql@localhost ~]$ mysql -uroot -P3306 -S /data/mysql/3307/mysql3307.sock -p
Enter password:
ERROR 1862 (HY000): Your password has expired. To log in you must change it using a client that supports expired passwords.
解决方法:
(1)先关闭数据库实例,由于不能登录,所以只能有 kill -9 执行杀掉进程。
(2)再配置文件中,添加选项 skip-grant-tables
(3)重启数据库实例
(4)免密码登录:
mysql -uroot -P3306 -S /data/mysql/3306/mysql3306.sock
(5.1)修改密码过期策略:
MySQL [none] use mysql
MySQL [mysql] update user set password_expired= N where user= root
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
(5.2)修改密码:
MySQL [none] use mysql
MySQL [mysql] update user set authentication_string = password(Yxc@3306) where user= root ;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
(6)重启数据库实例
[mysql@localhost ~]$ mysqladmin -uroot -S /data/mysql/3306/mysql3306.sock shutdown
cd /usr/local/mysql/bin
./mysqld_safe --defaults-file=/data/mysql/3306/my3306.cnf --user=mysql
7、创建用户
MySQL [(none)] create USER root @ % IDENTIFIED WITH mysql_native_password BY Yxc3307
Query OK, 0 rows affected (0.00 sec)
MySQL [(none)] grant all privileges on *.* to root @ %
Query OK, 0 rows affected (0.00 sec)
说明:
MySQL8.0 之前的版本密码加密规则:mysql_native_password,
MySQL8.0 密码加密规则:caching_sha2_password
8、navicat 登录
