安裝環(huán)境：
docker -> centos7.2.1511
1、進入下載目錄
cd /usr/local/src
2、下載mysql5.7 編譯安裝需要boost 庫
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.25.tar.gz
獲取以前老的版本下載地址：
http://downloads.mysql.com/archives/community/
3、解壓
tar -zxvf mysql-boost-5.7.25.tar.gz
4、安裝依賴包
yum install -y gcc gcc-c++ cmake ncurses ncurses-devel bison
5、添加用戶
cd /usr/local/src/mysql-5.7.25
useradd -s /sbin/nologin mysql
6、編譯并指定安裝目錄
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost
7、安裝
make && make install
---------------------------------------------配置-----------------------------------------------------
8、編輯 /etc/my.cnf（ 如果沒有則創(chuàng)建）
vim /etc/my.cnf
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
port = 3306
socket = /tmp/mysql.sock
user = mysql
basedir = /usr/local/mysql
datadir = /data/mysql/data
pid-file = /data/mysql/mysql.pid
log_error = /data/mysql/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /data/mysql/mysql-slow.log
skip-external-locking
key_buffer_size = 32M
max_allowed_packet = 1024M
table_open_cache = 128
sort_buffer_size = 768K
net_buffer_length = 8K
read_buffer_size = 768K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
thread_cache_size = 16
query_cache_size = 16M
tmp_table_size = 32M
performance_schema_max_table_instances = 1000
explicit_defaults_for_timestamp = true
#skip-networking
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535
log_bin=mysql-bin
binlog_format=mixed
server_id = 232
expire_logs_days = 10
early-plugin-load = ""
default_storage_engine = InnoDB
innodb_file_per_table = 1
innodb_buffer_pool_size = 128M
innodb_log_file_size = 32M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
[myisamchk]
key_buffer_size = 32M
sort_buffer_size = 768K
read_buffer = 2M
write_buffer = 2M
9、創(chuàng)建 MySQL 相關(guān)目錄及權(quán)限
chown -R mysql:mysql /usr/local/mysql
mkdir -p /data/mysql/{data,log,tmp}
chown -R mysql:mysql /data/mysql
10、添加 MySQL 環(huán)境變量
vim /etc/profile
在 ~/.bashrc文件下添加如下語句
export MYSQL_HOME=/usr/local/mysql
export PATH=${MYSQL_HOME}/bin:$PATH
保存后，使環(huán)境變量生效
source /etc/profile
11、初始化mysql（當(dāng)前路徑是 /usr/local/mysql ）
./bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
–initialize-insecure使用空密碼。你應(yīng)該在生產(chǎn)中及時修改密碼。
或者使用--initialize這樣的話，會為 root 用戶生成一個隨機的密碼。
12、拷貝可執(zhí)行配置文件
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
13、設(shè)置開機自啟動并啟動
systemctl enable mysqld
service mysqld start
14、登陸MySQL（無密碼）
./bin/mysql -hlocalhost -uroot -p
備注：
1、
centos在docker容器中不存在service這個命令，會報錯bash: service: command not found所以要進行安裝yum install initscripts -y
2、本地鏈接mysql時:
Host 'gateway' is not allowed to connect to this MySQL server;
mysql> use mysql;
Database changed
mysql> select 'host' from user where user='root' ;
+------+| host |
+------+| host |
+------+
1 row in set (0.00 sec)
mysql> update user set host = '%' where user ='root';
Query OK, 1 row affected (0.00 sec)Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> select 'host' from user where user='root';
+------+| host |
+------+| host |
+------+
1 row in set (0.00 sec)
3、報錯
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
原因一：是因為不存在
/tmp/mysql.sock這個文件，但是在/tmp/目錄下沒有找到此文件find / -name mysql.sock ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
原因二：權(quán)限問題
chown -R mysql:mysql /data/mysql
