在CentOS7.4上手动编译安装Mysql-5.7.20

实验环境:
CentOS 7.4

mysql软件: mysql-boost-5.7.20.tar.gz

1.安装编译工具

yum -y install \
ncurses \
ncurses-devel \
bison \
cmake\
gcc \
gcc-c++ \
make

2.解压包

tar xf mysql-boost-5.7.20.tar.gz

3.定制配置

cd mysql-5.7.20/

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \                     //5.7版本必须添加这个参数
-DWITH_SYSTEMD=1

4.编译并安装

make && make install

5.添加程序帐户，并相关设置

useradd -s /sbin/nologin  mysql

chown -R mysql:mysql /usr/local/mysql/

chown mysql:mysql /etc/my.cnf

6.修改配置文件

vi /etc/my.cnf

[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

7.设置环境变量

echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile                //把这两个路径添加到环境变量中，并放到profile文件中使之开机自运行，否则不生效

echo 'export PATH' >> /etc/profile                                                       //把PATH设为全局变量

source /etc/profile

8.初始化数据库

cd /usr/local/mysql/

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

9.添加到systemctl系统服务

cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/

systemctl daemon-reload

systemctl start mysqld

netstat -anpt | grep 3306

systemctl enable mysqld

10.Mysql设置帐户和密码,默认无密码

mysqladmin -u root -p password "abc123"

mysql -u root -p
