0、環境

本文操作系統: CentOS 7.2.1511 x86_64
MySQL 版本: 5.7.19

安裝之前先把開發環境裝一下

yum -y install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre* make gd-devel libjpeg-devel 
libpng-devel libxml2-devel bzip2-devel libcurl-devel glib2 glib2-devel GeoIP-devel ncurses-devel zlib zlib-devel

yum install gcc* net-tools perl

yum -y groupinstall "Development Tools" ##會一次安裝很多常用的開發包，包括gcc，g++等編譯文件必須的工具。

1、卸載系統自帶的 mariadb-lib

[root@centos-linux ~]# rpm -qa|grep mariadb
 mariadb-libs-5.5.44-2.el7.centos.x86_64 
[root@centos-linux ~]# rpm -e mariadb-libs-5.5.44-2.el7.centos.x86_64 --nodeps

2、下載我們需要的mysql5.7.19 rpm安裝包，官網mysql安裝包是mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar下載地址

[root@centos-linux ~]# wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar

然後解壓

　[root@linux_node_1 src]# tar -xvf mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar 
  mysql-community-libs-compat-5.7.16-1.el7.x86_64.rpm
  mysql-community-devel-5.7.16-1.el7.x86_64.rpm
  mysql-community-minimal-debuginfo-5.7.16-1.el7.x86_64.rpm
  mysql-community-libs-5.7.16-1.el7.x86_64.rpm
  mysql-community-common-5.7.16-1.el7.x86_64.rpm
  mysql-community-embedded-compat-5.7.16-1.el7.x86_64.rpm
  mysql-community-test-5.7.16-1.el7.x86_64.rpm
  mysql-community-embedded-devel-5.7.16-1.el7.x86_64.rpm
  mysql-community-server-minimal-5.7.16-1.el7.x86_64.rpm
  mysql-community-server-5.7.16-1.el7.x86_64.rpm
  mysql-community-client-5.7.16-1.el7.x86_64.rpm
  mysql-community-embedded-5.7.16-1.el7.x86_64.rpm
3、安裝
依次執行（幾個包有依賴關系，所以執行有先後）下面命令安裝
[root@centos-linux ~]# rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm 
[root@centos-linux ~]# rpm -ivh mysql-community-libs-5.7.16-1.el7.x86_64.rpm
[root@centos-linux ~]# rpm -ivh mysql-community-client-5.7.16-1.el7.x86_64.rpm 
[root@centos-linux ~]# rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm
在安裝rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm的時候報錯如下：

  [root@linux_node_1 src]# rpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm 
  warning: mysql-community-server-5.7.16-1.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-5.7.16-1.el7.x86_64
  libaio.so.1(LIBAIO_0.1)(64bit) is needed by mysql-community-server-5.7.16-1.el7.x86_64
  libaio.so.1(LIBAIO_0.4)(64bit) is needed by mysql-community-server-5.7.16-1.el7.x86_64
 


  這個報錯的意思是需要安裝libaio包：可以yum安裝一下，安裝 libaio-0.3.107-10.el6.x86_64.rpm，下載地址：
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm

4、數據庫初始化

為了保證數據庫目錄為與文件的所有者為 mysql 登陸用戶，如果你是以 root 身份運行 mysql 服務，需要執行下面的命令初始化
mysqld --initialize --user=mysql


  如果是以 mysql 身份運行，則可以去掉 --user 選項。

  另外 --initialize 選項默認以“安全”模式來初始化，則會為 root 用戶生成一個密碼並將該密碼標記為過期，登陸後你需要設置一個新的密碼，而使用 --initialize-insecure 命令則不使用安全模式，則不會為 root 用戶生成一個密碼。

  這裏演示使用的 --initialize 初始化的，會生成一個 root 賬戶密碼，密碼在log文件裏，紅色區域的就是自動生成的密碼
  [root@linux_node_1 src]# cat /var/log/mysqld.log 
  2016-12-07T04:41:58.028558Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
  2016-12-07T04:41:58.315188Z 0 [Warning] InnoDB: New log files created, LSN=45790
  2016-12-07T04:41:58.355114Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
  2016-12-07T04:41:58.418448Z 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: 7cc98831-bc37-11e6-a263-000c29f902dc.
  2016-12-07T04:41:58.419935Z 0 [Warning] Gtid table is not ready to be used. Table ‘mysql.gtid_executed‘ cannot be opened.
  2016-12-07T04:41:58.420558Z 1 [Note] A temporary password is generated for root@localhost:hm9dKgzQdm:W
 

  現在啟動mysql數據庫systemctl start mysqld.service
  [root@linux_node_1 src]# systemctl start mysqld.service
  [root@linux_node_1 src]# mysql -uroot -p
  Enter password:

  mysql>
 
  5、修改密碼
 
  該密碼被標記為過期了，如果想正常使用還需要修改密碼
 
mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

 
  以前的 password()函數將會被拋棄，官方建議使用下面的命令來修改密碼
 
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘new_password‘;

 
  同時，如果你設置的密碼過於簡單也會報錯。
 
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘123‘;
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

具體關於設置密碼的規則，可以看官方文檔；

這裏我們註意設置密碼 長度要大於8，同時要有數字，大小寫，特殊字符。

遠程權限

  grant all privileges on *.* to root@‘%‘ identified by ‘Password123!‘ with grant option;

  flush privileges;

這樣就用遠程客戶端登錄了。

記一次 centos7.2 rpm方式安裝mysql5.7.19 報錯
