MySql5.7

1、安装依赖软件

yum install -y gcc-c++ make cmake bison bison-devel ncurses-devel libaio-devel perl perl-Data-Dumper

 

2、创建用户与用户组

cat /etc/passwd | grep mysql

cat /etc/group | grep mysql

groupadd mysql

useradd -r -g mysql mysql

 

3、解压boost和mysql安装包

tar xzf boost_1_59_0.tar.gz

tar xzf mysql-boost-5.7.17.tar.gz

 

4、创建MySQL数据目录

mkdir -p /data/mysql

cd mysql-5.7.17

 

5、预编译

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/data/mysql -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/data/software/mysql/boost_1_59_0

 

6、编译安装

make -j `grep processor /proc/cpuinfo | wc -l` #编译很消耗系统资源，小内存可能编译通不过

make install

 

7、设置开机自动开启

/bin/cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld on

 

8、修改/etc/my.cnf

[client]

port = 3306

socket = /tmp/mysql.sock

default-character-set = utf8

 

[mysqld]

port = 3306

socket = /tmp/mysql.sock

 

basedir = /usr/local/mysql

datadir = /data/mysql

pid-file = /data/mysql/mysql.pid

user = mysql

bind-address = 0.0.0.0

server-id = 1

 

init-connect = 'SET NAMES utf8'

character-set-server = utf8

log_bin_trust_function_creators=1

 

#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 = 4M

binlog_cache_size = 1M

max_heap_table_size = 8M

tmp_table_size = 16M

 

read_buffer_size = 2M

read_rnd_buffer_size = 8M

sort_buffer_size = 8M

join_buffer_size = 8M

key_buffer_size = 4M

 

thread_cache_size = 8

 

query_cache_type = 1

query_cache_size = 8M

query_cache_limit = 2M

 

ft_min_word_len = 4

 

log_bin = mysql-bin

binlog_format = mixed

expire_logs_days = 30

 

log_error = /data/mysql/mysql-error.log

slow_query_log = 1

long_query_time = 1

slow_query_log_file = /data/mysql/mysql-slow.log

 

performance_schema = 0

explicit_defaults_for_timestamp

 

lower_case_table_names = 1

sql_mode='NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_ZERO_DATE,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER'

 

 

skip-external-locking

 

default_storage_engine = InnoDB

#default-storage-engine = MyISAM

innodb_file_per_table = 1

innodb_open_files = 500

innodb_buffer_pool_size = 64M

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 = 2M

innodb_log_file_size = 32M

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 = 10G

myisam_repair_threads = 1

 

interactive_timeout = 28800

wait_timeout = 28800

 

[mysqldump]

quick

max_allowed_packet = 16M

 

[myisamchk]

key_buffer_size = 8M

sort_buffer_size = 8M

read_buffer = 4M

write_buffer = 4M

 

9、初始化数据库

/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

 

10、启动数据库

service mysqld start

 

11、设置数据库密码及授权

dbrootpwd=Ces123456 #数据库root密码

/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1' identified by \"$dbrootpwd\" with grant option;"

/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'localhost' identified by \"$dbrootpwd\" with grant option;"

 

12、添加环境变量 vi /etc/profile

export MYSQL_HOME=/usr/local/mysql

export PATH=$PATH:$MYSQL_HOME/bin

 

13、修改root密码和授权新用户

mysql> set password=password('Ces123456');

mysql> grant all on *.* to root@'%' identified by 'Ces123456';

mysql> flush privileges;

mysql> select user,host,authentication_string from mysql.user;

 

14、开放3306端口号

vi /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

service iptables restart

在另一台web服务器上安装nc测试端口连通性

yum install nc -y

nc -z -w 1 192.168.1.247 3306
