centos7.4 tar包安装 MySQL5.7.22，

一、CentOS7.4系统自带mariadb

# 查看系统自带的Mariadb
[root@vmtest ~]# rpm -qa|grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64

# 卸载系统自带的Mariadb
[root@vmtest ~]# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

# 删除etc目录下的my.cnf
[root@vmtest ~]# rm /etc/my.cnf

二、检查mysql是否存在

# 检查mysql是否存在
[root@VMTest ~]# rpm -qa | grep mysql
[root@VMTest ~]#

三、查看用户和组是否存在

1）检查mysql组合用户是否存在

# 检查mysql组和用户是否存在，如无则创建
[root@VMTest ~]# cat /etc/group | grep mysql
[root@VMTest ~]# cat /etc/passwd | grep mysql

# 查询全部用户（只是做记录，没必要执行）
[root@VMTest ~]# cat /etc/passwd|grep -v nologin|grep -v halt|grep -v shutdown|awk -F ":" '{print $1 "|" $3 "1" $4}' | more
root|010
sync|510
mysql|99711001

2）若不存在，则创建mysql组和用户

# 创建mysql用户组
[root@VMTest ~]# groupadd mysql

# 创建一个用户名为mysql的用户，并加入mysql用户组
[root@VMTest ~]# useradd -g mysql mysql

# 制定password 为111111
[root@VMTest ~]# passwd mysql
Changing password for user mysql.
New password:
BAD PASSWORD: The password is a palindrome
Retype new password:
passwd: all authentication tokens updated successfully.

四、下载mysql的tar包

https://dev.mysql.com/downloads/mysql/5.7.html#downloads

五、上传第四步下载的mysql TAR包到

# 进入/usr/local/src文件夹
[root@VMTest ~]# cd /usr/local/src/

# 上传mysql TAR包
[root@VMTest src]# rz

# 解压tar文件
[root@VMTest src]# tar xvf mysql-5.7.22-el7-x86_64.tar

# 解压mysql-5.7.22-el7-x86_64.tar.gz
[root@VMTest src]# tar -zxvf mysql-5.7.22-el7-x86_64.tar.gz

# 解压后的文件移动到/usr/local文件夹
[root@VMTest src]# mv mysql-5.7.22-el7-x86_64 /usr/local

# 进入/usr/local下，修改为mysql
[root@VMTest src]# cd /usr/local
[root@VMTest local]# mv mysql-5.7.22-el7-x86_64 mysql

六、更改所属的组和用户

# 更改所属的组和用户
[root@VMTest local]# chown -R mysql mysql/
[root@VMTest local]# chgrp -R mysql mysql/
[root@VMTest local]# cd mysql/

[root@VMTest mysql]# mkdir data

[root@VMTest mysql]# chown -R mysql:mysql data

七、进入mysql文件夹，并安装mysql

# 进入mysql
[root@VMTest etc]# cd /usr/local/mysql/

# 安装mysql
[root@VMTest mysql]# bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ 
                     --datadir=/usr/local/mysql/data/
or(推荐):
[root@VMTest mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ 
                     --datadir=/usr/local/mysql/data/

2018-07-04 15:46:02 [WARNING] 5mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-07-04 15:46:05 [WARNING] The bootstrap log isn't empty:
2018-07-04 15:46:05 [WARNING] 2018-07-04T15:46:02.728710Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
2018-07-01T15:46:02.729161Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2018-07-04 T15:46:02.729167Z 0 [Warning] Changed limits: table_open_cache: 407 (requested 2000)

[root@VMTest mysql]# cp ./support-files/mysql.server /etc/init.d/mysqld
[root@VMTest mysql]# chown 777 /etc/my.cnf
[root@VMTest mysql]# chmod +x /etc/init.d/mysqld

八、在/etc下创建my.cnf文件

# 进入/etc文件夹下
[root@VMTest mysql]# cd /etc

# 创建my.cnf文件
[root@VMTest etc]# touch my.cnf

# 编辑my.cnf
[root@VMTest etc]# vim my.cnf

1）my.cnf添加如下内容：

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8

[mysqld]
# 设置3306端口
port = 3306

# 设置mysql的安装目录
basedir=/usr/local/mysql

# 设置mysql数据库的数据的存放目录
datadir=/usr/local/mysql/data

# 允许最大连接数
max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8

# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M

2）查看my.cnf内容

# 查看my.cnf文件
[root@VMTest mysql]# cat /etc/my.cnf

九、启动mysql

# 启动mysql
[root@VMTest mysql]# /etc/init.d/mysqld start
or
[root@VMTest mysql]# ./mysqld --defaults-file=/etc/my.cnf --user=root
MySQL manager or server PID file could not be found! [FAILED]

解决：

# 1、查看进程
[root@VMTest mysql]# ps aux|grep mysql
root 10031 0.0 0.1 113264 1616 pts/0 S 14:36 0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/iZ2ze3hm3gyjyjz628l7rgZ.pid
mysql 10220 0.0 19.1 1140876 195072 pts/0 Sl 14:36 0:02 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=iZ2ze3hm3gyjyjz628l7rgZ.err --pid-file=/usr/local/mysql/data/iZ2ze3hm3gyjyjz628l7rgZ.pid --port=3306
root 10421 0.0 0.0 112660 968 pts/0 R+ 15:51 0:00 grep --color=auto mysql

# 2、杀死进程
[root@VMTest mysql]# kill -9 10031
[root@VMTest mysql]# kill -9 10220

# 3、重启mysql
[root@VMTest mysql]# /etc/init.d/mysqld restart
Shutting down MySQL..
Starting MySQL.

十、设置开机启动

#设置开机启动
[root@VMTest mysql]# chkconfig --level 35 mysqld on
[root@VMTest mysql]# chkconfig --list mysqld

[root@VMTest mysql]# chmod +x /etc/rc.d/init.d/mysqld
[root@VMTest mysql]# chkconfig --add mysqld
[root@VMTest mysql]# chkconfig --list mysqld
[root@VMTest mysql]# service mysqld status
SUCCESS! MySQL running (4475)

十一、修改配置文件

# 进入/etc/profile文件夹
[root@VMTest mysql]# vim /etc/profile

1）修改/etc/profile，在最后添加如下内容

# 修改/etc/profile文件
#set mysql environment
export PATH=$PATH:/usr/local/mysql/bin

# 使文件生效
[root@VMTest mysql]# source /etc/profile

十二、获得mysql初始密码

# 1、获得mysql初始密码
[root@VMTest bin]# cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2017-04-17 17:40:02
_pB*3VZl5T<6

# 2、修改密码
[root@VMTest bin]# mysql -uroot -p
Enter password:

十三、添加远程访问权限

# 添加远程访问权限
mysql> use mysql

You can turn off this feature to get a quicker startup with -A
Database changed

mysql> update user set host='%' where user='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 1 Changed: 0 Warnings: 0

mysql> select host,user from user;
+-----------+---------------+
| host | user |
+-----------+---------------+
| % | root |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+---------------+
3 rows in set (0.00 sec)

十四、重启mysql生效

# 重启mysql
[root@VMTest bin]# /etc/init.d/mysqld restart
Shutting down MySQL..
Starting MySQL.

备注：

由于安装在/usr/local下面的mysql，因此可以在任何文件夹启动mysql

若安装在别的文件夹，请执行以下命令：
# 为了在任何目录下可以登录mysql
ln -s /你的mysql路径/mysql /usr/local/mysql
