Centos7编译安装mysql5.7.9

mysql5.7有更好的性能，对多核CPU和固态硬盘有着更好的优化，

更好的InnoDB引擎，更为健壮的复制功能,原生json的支持

加上一些程序的新版本也偏向优先支持MySQL5.7，所以我们有必要安装配置一下mysql5.7

平台：Centos 7

版本：Centos 5.7.9

一 准备工作

安装依赖

$ yum -y install gcc gcc-c++ ncurses ncurses-devel cmake

如果是centos6并已经装好cmake，需要检查一下cmake的版本，编译MySQL5.7需要的最低版本为2.8

下载源码包

$ wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.12.tar.gz

$ wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.12.tar.gz

编译MySQL5.7需要boost支持，如果事先没有装好boost，就下载下面这个。

添加MySQL用户

$ sudo useradd -M -s /sbin/nologin     mysql

安装

解压然后进入

$ tar -xf mysql-boost-5.7.12.tar.gz && cd mysql-5.7.12

预编译

$ cmake /

    -DCMAKE_INSTALL_PREFIX=/home/nick/mysql     /

    -DMYSQL_UNIX_ADDR=/home/nick/mysql/mysql.sock /

    -DDEFAULT_CHARSET=utf8 /

    -DDEFAULT_COLLATION=utf8_general_ci /

    -DWITH_INNOBASE_STORAGE_ENGINE=1 /

    -DWITH_ARCHIVE_STORAGE_ENGINE=1 /

    -DWITH_BLACKHOLE_STORAGE_ENGINE=1 /

    -DMYSQL_DATADIR=/home/nick/mysql/data /

    -DMYSQL_TCP_PORT=3306

    -DWITH_BOOST=boost

编译安装，最好开个screen

$ make && make install

这一步时间会比较长，你可以出去吃个饭或者睡一觉，如果在上班的话，那就先忙其他的，两三个个小时后看看。

完成之后

 $ cd /home/nick/mysql && mkdir etc tmp var log data

 #复制一份配置文件，有需要的话进去修改一下

 cp support-files/my-default.cnf  etc/my.cnf

我看了下，默认的话其实并没有什么配置，所以可以参照下面的

port = 3306

socket = /home/nick/mysql/mysql.sock

default-character-set = utf8mb4

[mysqld]

port = 3306

socket = /home/nick/mysql/mysql.sock

basedir = /home/nick/mysql

datadir = /home/nick/mysql/data

pid-file = /home/nick/mysql/log/mysql.pid

user = mysql

bind-address = 0.0.0.0

server-id = 1

init-connect = 'SET NAMES utf8mb4'

character-set-server = utf8mb4

#skip-name-resolve

#skip-networking

back_log = 300

max_connections = 1000

max_connect_errors = 6000

open_files_limit = 65535

table_open_cache = 128

max_allowed_packet = 1M

binlog_cache_size = 1M

max_heap_table_size = 2M

tmp_table_size = 4M

read_buffer_size = 1M

read_rnd_buffer_size = 2M

sort_buffer_size = 2M

join_buffer_size = 2M

key_buffer_size = 1M

thread_cache_size = 8

query_cache_type = 1

query_cache_size = 2M

query_cache_limit = 1M

ft_min_word_len = 4

log_bin = mysql-bin

binlog_format = mixed

expire_logs_days = 30

log_error = /home/nick/mysql/log/mysql-error.log

slow_query_log = 1

long_query_time = 1

slow_query_log_file = /home/nick/mysql/log/mysql-slow.log

performance_schema = 0

explicit_defaults_for_timestamp

#lower_case_table_names = 1

skip-external-locking

default_storage_engine = InnoDB

#default-storage-engine = MyISAM

innodb_file_per_table = 1

innodb_open_files = 500

innodb_buffer_pool_size = 16M

innodb_write_io_threads = 4

innodb_read_io_threads = 4

innodb_thread_concurrency = 0

innodb_purge_threads = 1

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 1M

innodb_log_file_size = 8M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

bulk_insert_buffer_size = 8M

myisam_sort_buffer_size = 8M

myisam_max_sort_file_size = 1G

myisam_repair_threads = 1

interactive_timeout = 28800

wait_timeout = 28800

[mysqldump]

quick

max_allowed_packet = 8M

然后初始化mysql

$ /home/nick/mysql/bin/mysqld --initialize-insecure --user=nick --basedir=/home/nick/mysql --datadir=/home/nick/mysql/data

之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃

“–initialize”会生成一个随机密码(~/.mysql_secret)，而”–initialize-insecure”不会生成密码

–datadir目标目录下不能有数据文件

注意 这次安装的MySQL5.7.12是没有生产 ~/.mysql_secret文件的，同时也没有密码 输入用户名就可以直接登录。

启动MySQL

$ /home/nick/mysql/bin/mysqld --defaults-file=/home/nick/mysql/etc/my.cnf

登录后修改root密码

mysql5.7以后mysql.user表就没有了password字段

update mysql.user set authentication_string=password('123456') where user='root' and Host = 'localhost';

plush privileges;

使用supervisor来管理MySQL

supervisor的部署就不多说了，直接看配置

[program:mysql]

command=/home/nick/mysql/bin/mysqld --defaults-file=/home/nick/mysql/etc/my.cnf

directory=/home/nick/mysql

user=nick

MySQL5.7就此安装完毕
