Mysql编译安装

mysql应用编译安装：

• 修改配置文件：

# wget -c https://downloads.mysql.com/archives/get/file/mysql-5.6.25.tar.gz
# apt-get -y install make gcc g++ cmake perl vim
# apt-get install make gcc g++ libcurl3-openssl-dev libfreetype6-dev libmcrypt-dev
# apt-get install libpcre3 libpcre3-dev zlib1g-dev libssl-dev build-essential
# apt-get install openssl libssl-dev
# groupadd -r mysql
# useradd -g mysql -r -d /mydata/data mysql
# mkdir /mydata/data -pv
# tar xf mysql-5.6.25.tar.gz 
# cd mysql-5.6.25
# vim cmd-line-utils/libedit/terminal.c
		把terminal_set方法中的 char buf[TC_BUFSIZE]; 这一行注释,再把 area = buf;改为 area = NULL;
		protected int
		terminal_set(EditLine *el, const char *term)
		{ 
		int i; 
		/*char buf[TC_BUFSIZE];*/
		char *area;
		...
		area = NULL;
# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql 
		  -DMYSQL_DATADIR=/mydata/data 
		  -DSYSCONFDIR=/etc 
		  -DWITH_INNOBASE_STORAGE_ENGINE=1 
		  -DWITH_ARCHIVE_STORAGE_ENGINE=1 
		  -DWITH_BLACKHOLE_STORAGE_ENGINE=1 
		  -DWITH_READLINE=1 
		  -DWITH_SSL=system 
		  -DWITH_ZLIB=system 
		  -DWITH_LIBWRAP=0 
		  -DMYSQL_UNIX_ADDR=/tmp/mysql.sock 
		  -DDEFAULT_CHARSET=utf8 
		  -DDEFAULT_COLLATION=utf8_general_ci
# make
# make install
# cd /usr/local/mysql
# sudo chown -R mysql:mysql ./
# sudo chown -R mysql:mysql /mydata/data
# cp support-files/my-default.cnf /etc/my.cnf
# sudo chown mysql:mysql /etc/my.cnf

• 修改配置文件：

# sudo vi /etc/my.cnf 
	[client] 
	port = 3306 
	socket = /usr/local/mysql/data/mysql.sock

	[mysqld] 
	port = 3306 
	socket = /usr/local/mysql/data/mysql.sock 
	basedir = /usr/local/mysql 
	datadir = /usr/local/mysql/data

• 初始化数据库

# cd /usr/local/mysql 
# sudo scripts/mysql_install_db –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data/

• 启动mysql服务

# 方法1：
	# 直接启动 
	# bin/mysqld_safe &
	# 检查MySQL服务是否启动：
	# ps -ef |grep mysql
# 方法2：
	# 通过服务启动
	# 添加服务，复制启动脚本到/etc/init.d目录：

	# cd /usr/local/mysql/
	# cp support-files/mysql.server /etc/init.d/mysql
	# 设置文本的权限：
	# sudo chmod 755 /etc/init.d/mysql

	# 启动：
	# sudo /etc/init.d/mysql start
	# (关闭mysql服务：sudo /etc/init.d/mysql stop)
	# 或者
	# sudo service mysql start
	# (关闭mysql服务：sudo service mysql stop)
	# 检查MySQL服务是否启动：
	# ps -ef |grep mysql

• 配置环境变量

# 为了直接调用mysql，需要将mysql的bin目录加入PATH环境变量。
# 编辑/etc/profile.d/：
# sudo vim /etc/profile.d/mysql
	PATH=$PATH:/usr/local/mysql/bin
	export PATH
# 关闭文件，运行下面的命令，让配置立即生效：
# source /etc/profile

• 修改root密码（因为默认密码为空）

# mysql -h127.0.0.1 -uroot -p
# update mysql.user set password=password('root') where user='root'; 
# flush privileges;
# service mysql restart

• 开机自启动

# update-rc.d nginx defaults 99

• mysql测试语句：

# mysql> select now(),user(),version(); 
+---------------------+------------------+-----------+
| now()               | user()           | version() |
+---------------------+------------------+-----------+
| 2018-08-27 19:00:59 | evescn@localhost | 5.6.25    |
+---------------------+------------------+-----------+
# CREATE DATABASE IF NOT EXISTS evescn DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
# CREATE TABLE IF NOT EXISTS `runoob_tbl`(
	   `runoob_id` INT UNSIGNED AUTO_INCREMENT,
	   `runoob_title` VARCHAR(100) NOT NULL,
	   `runoob_author` VARCHAR(40) NOT NULL,
	   `submission_date` DATE,
	   PRIMARY KEY ( `runoob_id` )
	)ENGINE=InnoDB DEFAULT CHARSET=utf8;
# INSERT INTO runoob_tbl
	(runoob_title, runoob_author, submission_date)
	VALUES
	("学习 MySQL", "菜鸟教程", NOW());
# INSERT INTO runoob_tbl 
	(runoob_title, runoob_author, submission_date)
	VALUES
	("学习 PHP", "菜鸟教程", NOW());
