Mysql源码编译安装

安装环境说明：

安装步骤：

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

cd /usr/local/source
wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.9.tar.gz[/code] 
附：百度云盘分享 http://pan.baidu.com/s/1qYo2luW

添加用户组

groupadd mysql
useradd -r -g mysql mysql


4.编译&安装

tar xzf boost_1_59_0.tar.gz
tar xzf mysql-5.7.9.tar.gz
mkdir -p /data/mysql
cd mysql-5.7.9
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/data/mysql
-DDOWNLOAD_BOOST=1
-DWITH_BOOST=../boost_1_59_0
-DSYSCONFDIR=/etc
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_PARTITION_STORAGE_ENGINE=1
-DWITH_FEDERATED_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_MYISAM_STORAGE_ENGINE=1
-DENABLED_LOCAL_INFILE=1
-DENABLE_DTRACE=0
-DDEFAULT_CHARSET=utf8mb4
-DDEFAULT_COLLATION=utf8mb4_general_ci
-DWITH_EMBEDDED_SERVER=1
make
make install


5.启动脚本，设置开机自启动

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on


6.配置mysql的/etc/my.cnf

仅供参考，实际可根据生产环境调整

[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8mb4

[mysqld]
port = 3306
socket = /tmp/mysql.sock

datadir = /data/mysql
pid-file = /data/mysql/mysql.pid
user = mysql
bind-address = 0.0.0.0
server-id = 1
init-connect = 'SET NAMES utf8mb4'
character-set-server = utf8mb4
back_log = 300
max_connections = 1000
max_connect_errors = 6000

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

[mysqldump]
quick
max_allowed_packet = 16M

[myisamchk]
key_buffer_size = 8M
sort_buffer_size = 8M
read_buffer = 4M
write_buffer = 4M


7.初始化数据库

/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local
9dd9
/mysql --datadir=/data/mysql


8.启动数据库

service mysqld start


9.设置root密码

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


10.开放防火墙端口

firewall-cmd --zone=public --add-port=80/tcp --permanent #开放指定端口
firewall-cmd --zone=public --add-port=3306/tcp --permanent
systemctl stop firewalld.service #重启防火墙
systemctl start firewalld.service
