LAMP环境之MySQL服务安装详细过程

1、安装Mysql环境依赖包
[root@localhost ~]#
yum -y install
gcc-c++
gcc
make
ncurses
ncurses-devel
bison
cmake

2、创建运行用户
[root@localhost ~] useradd -s /sbin/nologin mysql

3、编译安装
###上传mysql-boost-5.7.20.tar.gz到opt目录下###
[root@localhost ~]cd /opt
[root@localhost opt]# tar xzvf mysql-boost-5.7.20.tar.gz
[root@localhost opt]# cd /opt/mysql-5.7.20/
[root@localhost 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
-DWITH_SYSTEMD=1

[root@localhost mysql-5.7.20]# make && make install
[root@localhost mysql-5.7.20]#
用make -j2 安装开始时间：10：38 安装11:58 接下来是make install 时间开始13:37
------注意：如果在CMAKE的过程中有报错---
当报错解决后，需要把源码目录中的CMakeCache.txt文件删除，然后再重新CMAKE，否则错误依旧
------注意：make: *** No targets specified and no makefile found. Stop.解决方法

1. wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.6.tar.gz
2. tar zxvf ncurses-5.6.tar.gz
3. ./configure -prefix=/usr/local -with-shared-without-debug
4. make
5. make install

4、数据库目录进行权限调整
[root@localhost mysql-5.7.20]#chown -R mysql:mysql /usr/local/mysql/

5、调整配置文件
[root@localhost mysql-5.7.20]#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

chown mysql:mysql /etc/my.cnf

6、设置环境变量
echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
echo 'export PATH' >> /etc/profile
source /etc/profile

7、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

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

8、数据库开启自启、 关闭、状态
systemctl enable mysqld
systemctl start mysqld
systemctl stop mysqld
systemctl status mysqld
netstat -anpt | grep 3306

9、设置Mysql密码

mysqladmin -u root -p password //刚开始没密码是空的直接回车，然后输入密码123123,在此确认123123,这是在root账户下运行的

10、登录数据库
mysql -u root -p ##这个命令敲下，提示要输入密码,这个就是刚才设置的密码123123

这样就OK登录了！
