CentOS7 安装Mysql5.7(解压缩版)

1、下载安装包

http://dev.mysql.com/downloads/mysql/#downloads

推荐下载通用安装方法的TAR包

2.检查库文件是否存在，如有删除。

[[email protected] Desktop]$ rpm -qa | grep mysql

mysql-libs-5.1.52-1.el6_0.1.x86_64

[[email protected] ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps

[[email protected] ~]$

3.检查mysql组和用户是否存在，如无创建。

[[email protected] ~]$ cat /etc/group | grep mysql

mysql:x:490:

[[email protected] ~]$ cat /etc/passwd | grep mysql

mysql:x:496:490::/home/mysql:/bin/bash

以上为默认存在的情况，如无，执行添加命令：

[[email protected] ~]$groupadd mysql

[[email protected] ~]$useradd -r -g mysql mysql

//useradd -r参数表示mysql用户是系统用户，不可用于登录系统。

4.解压TAR包，更改所属的组和用户

[[email protected] ~]$ cd /usr/local/

[[email protected] local]$ tar xvf mysql-5.7.12-linux-glibc2.5-x86_64.tar

[[email protected] local]$ ls -l

total 1306432

-rwxr--r--. 1 root root  668866560 Jun  1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar

-rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz

[[email protected] local]$ tar xvfz mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz

[[email protected] local]$ mv mysql-5.7.12-linux-glibc2.5-x86_64 mysql

[[email protected] local]$ ls -l

[[email protected] local]$ chown -R mysql mysql/

[[email protected] local]$ chgrp -R mysql mysql/

[[email protected] local]$ cd mysql/

5.安装和初始化数据库

[[email protected] mysql]$ bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

2016-06-01 15:23:25 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize

2016-06-01 15:23:30 [WARNING] The bootstrap log isn't empty:

2016-06-01 15:23:30 [WARNING] 2016-06-01T22:23:25.491840Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead

2016-06-01T22:23:25.492256Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)

2016-06-01T22:23:25.492260Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

==如果改变默认安装路径，则需要

1）/etc/my.cnf、/etc/init.d/mysqld中修改

basedir='/apps/mysql'

datadir='/apps/mysql/data'

2）创建ln

mkdir -p /usr/local/mysql/bin

ln -s /apps/mysql/bin/mysqld /usr/local/mysql/bin/mysqld==

---

[[email protected] mysql]$

[[email protected] mysql]$ cp -a ./support-files/my-default.cnf /etc/my.cnf

[[email protected] mysql]$ cp -a ./support-files/mysql.server  /etc/init.d/mysqld

[[email protected] mysql]$ cd bin/

[[email protected] bin]# ./mysqld_safe --user=mysql &

6.初始化密码

mysql5.7会生成一个初始化密码，而在之前的版本首次登陆不需要登录。

[[email protected] bin]$ cat /root/.mysql_secret

# Password set for user '[email protected]' at 2016-06-01 15:23:25

,xxxxxR5H9

[[email protected] bin]$./mysql -uroot -p

Enter password:
