今天为大家介绍下MySQL 5.5.37的编译安装方式,在工作中编译安装也是我们常用的一种方式。希望通过这篇文章的介绍,,能够给大家提供一个安装思路!
A、创建mysql的安装目录和用户
mkdir -p /usr/local/mysql #安装mysql
mkdir -p /usr/local/mysql/data #存放数据库
groupadd mysql
useradd -r -g mysql mysql
B、yum安装依赖库
yum install gcc-c++ ncurses-devel –y
#安装错误信息:
CMake Error atcmake/readlineNaNake:83 (MESSAGE):
Curses library notfound. Please install appropriatepackage,
#解决方法
yum install ncurses-devel
rm CMakeCache.txt
C、编译安装cmake
tar -zxv -f cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./configure
make && make install
D、编译安装mysql5.5.37
tar -zxv -f mysql-5.5.37.tar.gz #解压
cd mysql-5.5.37
#编译参数
[root@localhost mysql-5.5.37]#
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DMYSQL_USER=mysql \
-DMYSQL_TCP_PORT=3306
#执行make命令
make
make install
E、检查是否安装成功
cd /usr/local/mysql/
[root@localhost mysql]#ls
bin COPYING data docs include INSTALL-BINARY lib man mysql-test README scripts share sql-bench support-files
#有bin等以上文件的话,恭喜你已经成功安装了mysql。
F、配置mysql5.5.37详细步骤
#把当前目录中所有文件的所有者设为root,所属组为mysql
chown -R root:mysql .
chown -R mysql:mysql data (可选)
#将mysql的启动服务添加到系统服务中
[root@localhost mysql]# cp support-files/my-medium.cnf /etc/my.cnf
cp:是否覆盖”/etc/my.cnf”? y
#mysql启动出错解决方法
1、问题
[root@localhost mysql]# /etc/rc.d/init.d/mysql statusMySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED][root@localhost mysql]# /etc/rc.d/init.d/mysql startStarting MySQL…The server quit without updating PID file(/usr/local/mysql/data/localhost.localdomain.pid). [FAILED]
2、原因
没有初始化权限表
3、解决办法
cd /usr/local/mysql(进入mysql安装目录)chown -R mysql.mysql .
#重新初始化数据库
[root@B2C-test-server mysql]# ./scripts/mysql_install_db–user=mysql
[root@B2C-test-server mysql]# /etc/init.d/mysql start
Starting MySQL.. SUCCESS!
#直接输入mysql启动数据库出错:
[root@localhost mysql]# mysql
-bash: mysql: command not found
#解决方法
[root@localhost mysql]# ln -s /usr/local/mysql/bin/mysql/usr/bin/
#修改MySQL的root用户的密码以及打开远程连接
[root@B2C-test-server mysql]# mysql -u root mysql
mysql> use mysql;
mysql> desc user;
mysql> GRANT ALL PRIVILEGES ON *.* TO root@”%” IDENTIFIED BY “root”; #为root添加远程连接的能力
mysql> update user set Password = password(‘123456′) where User=’root’; #设置root用户密码
mysql> select Host,User,Password from user where User=’root’;
mysql> flush privileges;
mysql> exit
#重新登录
[root@B2C-test-server mysql]# mysql -u root -p
Enter password:123456
#若还不能进行远程连接,关闭防火墙
[root@B2C-test-server mysql]# /etc/rc.d/init.d/iptables stop
G、设置mysql密码
#方法一:在mysql系统外,使用mysqladmin
[root@B2C-test-server mysql]# mysqladmin -u rootflush-privileges password ‘root’
#方法一:通过登录mysql系统
[root@B2C-test-server mysql]# mysql -u root -p
Enter password:
mysql> use mysql;
Database changed
mysql> update user set password=password(“root”)where user=’root’;
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> flush privileges;
mysql> exit;
H、Mysql root密码忘记解决方法
#方法一:
# /etc/init.d/mysqld stop
# mysqld_safe –user=mysql –skip-grant-tables –skip-networking&
# mysql -uroot mysql
mysql> update user setPassword=Password(‘newpassword’) where User=’root’;
mysql> flush privileges;
mysql> quit
# /etc/init.d/mysql restart
# mysql -uroot -penter password:
#方法二:
#修改MySQL的登录设置:
#在[mysqld]的段中加上一句:skip-grant-tables
如下:
[root@B2C-test-server mysql]# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
skip-grant-tables
#重启mysql
/etc/init.d/mysqld restartStoppingmysqld:
[ OK ]Startingmysqld: [ OK ]
#无密码登录:
# mysql
mysql> use mysql;update user setPassword=Password(‘root’) where User=’root’; mysql> flush privileges;
#退出,修改/etc/my.conf,删除skip-grant-tables,重启mysql。搞定
OK! mysql的编译安装今天就先介绍到这里吧!
