centos 7 安装 mysql 5.7

1、环境

Centos 7

2、下载

官方网站https://dev.mysql.com/downloads/mysql/5.7.html#downloads ，选择要下载的版本，centos 7 同red hat ，所以选择操作系统为red had。

下载文件如：mysql-5.7.18-1.el7.x86_64.rpm-bundle.tar

3、解压安装

使用命令"tar -xf mysql-5.7.18-1.el7.x86_64.rpm-bundle.tar",解压程序包

得到文件：

mysql-community-client-5.7.18-1.el7.x86_64.rpm
mysql-community-common-5.7.18-1.el7.x86_64.rpm
mysql-community-devel-5.7.18-1.el7.x86_64.rpm
mysql-community-embedded-5.7.18-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.18-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.18-1.el7.x86_64.rpm
mysql-community-libs-5.7.18-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.18-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.18-1.el7.x86_64.rpm
mysql-community-server-5.7.18-1.el7.x86_64.rpm
mysql-community-server-minimal-5.7.18-1.el7.x86_64.rpm
mysql-community-test-5.7.18-1.el7.x86_64.rpm

安装

rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.18-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.18-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.18-1.el7.x86_64.rpm

在安装过程中警告失败，如：

file /usr/share/mysql/czech/errmsg.sys from install of mysql-community-common-5.7.18-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64...

需要卸载mariadb

方式1：使用命令“rpm -qa|grep mariadb” 查找安装项，再使用命令“rpm -e --nodes *** ”，如：

[root@localhost mysql]# rpm -qa|grep mariadb
mariadb-libs-5.5.41-2.el7_0.x86_64
[root@localhost mysql]# rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64

方式2：使用命令“yum list installed |grep mariadb"查找安装项,再使用命令“yum remove *** ”，如：

[root@localhost mysql]# yum list installed |grep mariadb
mariadb-libs.x86_64 1:5.5.52-1.el7 @base
[root@localhost mysql]# yum remove mariadb-libs.x86_64

在安装过程种发生如下错误：

#rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm
warning: mysql-community-server-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
        libaio.so.1()(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
        libaio.so.1(LIBAIO_0.1)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64
        libaio.so.1(LIBAIO_0.4)(64bit) is needed by mysql-community-server-5.7.18-1.el7.x86_64

需要安装libaio

从centos 下载libaio

#wget http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm

安装libaio

#rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

卸载后正常，如

[root@localhost mysql]# rpm -ivh mysql-community-common-5.7.18-1.el7.x86_64.rpm
warning: mysql-community-common-5.7.18-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

[root@localhost mysql]#：

4、数据库初始化及设置用户密码

使用命令“mysqld --initialize --user=mysql ”，指定数据用户为“mysql”

使用命令“cat /var/log/mysqld.log” 查看数据库日志，查看原始密码，如：

[root@localhost mysql]# cat /var/log/mysqld.log
2017-07-02T15:30:25.274266Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2017-07-02T15:30:25.453876Z 0 [Warning] InnoDB: New log files created, LSN=45790
2017-07-02T15:30:25.556284Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2017-07-02T15:30:25.729883Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 5edc5c08-5f3b-11e7-baff-000c29931b60.
2017-07-02T15:30:25.780510Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2017-07-02T15:30:25.782981Z 1 [Note] A temporary password is generated for root@localhost: 26Fp?yMzd3W%

找到在内容中可以看到一个临时密码被创建，数据库用户名：root, 密码：26Fp?yMzd3W%

使用命令“systemctl start mysqld.service”,启动数据库，可通过“systemctl status mysqld.service” 查看服务状态，其他还有“stop/restart/enable/disable”等服务命令

使用命令“mysql -u root -p”，复制log密码登陆数据库,如：

[root@localhost ~]# mysql -u root -p

Enter password:

Welcome to the MySQL monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

现在已经成功登陆数据库了，在使用数据库前，需要更改密码，使用命令“ alter user 'root'@'localhost' IDENTIFIED BY 'yours password'; ”

5、防火墙开放端口3306。

[root@master ~]# firewall-cmd --add-port=3306/tcp --permanent

[root@master ~]# firewall-cmd --reload
