1.這裏我將mysql安裝在/usr/local/mysql目錄裏面，也可以安裝在其他地方
mkdir /usr/local/mysql
2.下載mysql壓縮包
wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
也可以本地下載好再上傳上去 百度mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz下載 一堆....
3.解壓並複製
tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.11-Linux-glibc2.5-x86_64/* /usr/local/mysql/
4.創建data目錄
mkdir /usr/local/mysql/data
5.創建mysql用戶和修改權限
useradd -g mysql mysql
groupadd mysql
chown -R mysql.mysql /usr/local/mysql/
6.初始化數據
下載libaio組件：
[root@localhost mysql]# yum search libaio
[root@localhost mysql]# yum install libaio
初始化：
[root@localhost mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

7. 複製配置文件到 /etc/my.cnf
cp -a ./support-files/my-default.cnf /etc/my.cnf (選擇y)
注意：可能會沒有這個文件，可以自己創建
這個文件詳細查看最後附(非常重要文件)
8. mysql的服務腳本放到系統服務中
cp -a ./support-files/mysql.server /etc/init.d/mysqld
cp /bin/* /usr/bin/
9.啓動服務 service mysqld start
10.修改密碼
mysql -u root mysql
注意：如果不行的話 在my.cnf文件最後加
skip-grant-tables 跳過密碼進入配置，再重啓mysql進入控制檯
進入mysql管理臺 執行
update mysql.user set authentication_string=PASSWORD('password') where User='root';
flush privileges;
11.
需要遠程連接需關閉防火牆 並賦予外部連接權限
開遠程登錄
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user; (%表示所有)
關防火牆
service iptables stop
chkconfig iptables off
12.進入控制檯
如果加了skip-grant-tables，則註釋掉，然後重啓 service mysqld restart
[root@localhost mysql]# mysql -u root -p 輸入密碼 進入控制檯
重置密碼：mysql> SET PASSWORD = PASSWORD('您得密碼');
Query OK, 0 rows affected, 1 warning (0.01 sec)
13.大功告成，可以用遠程客戶端連接啦。
附: 1. 初始化或啓動報錯 在data文件夾下localhost.localdomain.err文件找錯誤原因
2. my.cnf配置:

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended
