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！
一、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
二、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
三、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
四、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
五、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。
六、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
七、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;
八、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:
