Centos安装成功mysql-5.5.37

            摘自http://www.2cto.com/os/201404/296364.html（原文请关注）

这几天在centos下装mysql，这里记录一下安装的过程，方便以后查阅

Mysql5.5.37安装须要cmake，5.6版本号開始都须要cmake来编译，5.5以后的版本号应该也要装这个。

安装cmake

[plain] view plaincopyprint?01.[root@local ~]# wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz 
02.[root@local ~]# tar xvf cmake-2.8.12.2.tar.gz 
03.[root@local ~]# cd cmake-2.8.12.2 
04.[root@local cmake-2.8.12.2]#./bootstrap 
05.[root@local cmake-2.8.12.2]# make 
06.[root@local cmake-2.8.12.2]# make install 
[root@local ~]# wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz
[root@local ~]# tar xvf cmake-2.8.12.2.tar.gz
[root@local ~]# cd cmake-2.8.12.2
[root@local cmake-2.8.12.2]#./bootstrap
[root@local cmake-2.8.12.2]# make

[root@local cmake-2.8.12.2]# make install 安装mysql

[plain] view plaincopyprint?01.[root@local ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz 
02.[root@local ~]# tar xvf mysql-5.5.37.tar.gz 
03.[root@local ~]# cd mysql-5.5.37 
04.[root@local mysql-5.5.37]# cmake ./ 
[root@local ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz
[root@local ~]# tar xvf mysql-5.5.37.tar.gz
[root@local ~]# cd mysql-5.5.37
[root@local mysql-5.5.37]# cmake ./

可能还会报这个错，没有就跳过

[plain] view plaincopyprint?01.CMake Error at cmake/readline.cmake:83(MESSAGE): 
02.Curses library not found.  Pleaseinstall appropriate package, 
03.remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name islibncurses5-dev, on Redhat and derivates it is ncurses-devel.

说明centos系统没有ncurses-devel

[plain] view plaincopyprint?01.[root@local ~]# wgethttp://invisible-island.net/datafiles/release/ncurses.tar.gz 
02.[root@local ~]# cd ncurses-5.9 
03.[root@local ncurses-5.9]#./configure 
04.[root@local ncurses-5.9]# make 
05.[root@local ncurses-5.9]# make install 
[root@local ~]# wgethttp://invisible-island.net/datafiles/release/ncurses.tar.gz
[root@local ~]# cd ncurses-5.9
[root@local ncurses-5.9]#./configure
[root@local ncurses-5.9]# make
[root@local ncurses-5.9]# make install

再删除刚才编译生成的 CMakeCache.txt 文件，否则无法进行下一步

[plain] view plaincopyprint?01.[root@local mysql-5.5.37]# rm -f CMakeCache.txt 
[root@local mysql-5.5.37]# rm -f CMakeCache.txt

继续编译mysql

[plain] view plaincopyprint?01.[root@local ~]# cmake ./ 
02.[root@local ~]# make 
03.[root@local ~]# make install 
[root@local ~]# cmake ./
[root@local ~]# make
[root@local ~]# make install

这样，mysql默认将安装成功到/usr/local/mysql

创建mysql用户组

[plain] view plaincopyprint?01.[root@local ~]# groupadd mysql 
02.[root@local ~]# useradd –r –g mysql mysql 
03.[root@local ~]# chown –R mysql.mysql /usr/local/mysql  或者
[root@local ~]# groupadd mysql
[root@local ~]# useradd –r –g mysql mysql
[root@local ~]# chown mysql.mysql /usr/local/mysql

启动mysql

[plain] view plaincopyprint?01.[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql 
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql

这里可能会错误发生。没有就跳过：

[plain] view plaincopyprint?01.FATAL ERROR: Could not find./bin/my_print_defaults 
02.If you compiled from source, you need torun 'make install' to 
03.copy the software into the correct locationready for operation. 
04.If you are using a binary release, you musteither be at the top 
05.level of the extracted archive, or pass the --basedir option 
06.pointing to that location. 
FATAL ERROR: Could not find./bin/my_print_defaults
If you compiled from source, you need torun 'make install' to
copy the software into the correct locationready for operation.
If you are using a binary release, you musteither be at the top

解决方法：

[plain] view plaincopyprint?

01.[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 
[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

再启动mysql

[plain] view plaincopyprint?

01.[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql 
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql

注冊mysql服务，开机自己主动启动

1.设置mysql配置文件到/etc文件夹

[plain] view plaincopyprint?01.[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf 
[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf

2.设置mysql开机自启

[plain] view plaincopyprint?01.[root@local ~]# cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 
02.[root@local ~]# chmod +x /etc/init.d/mysql 
03.[root@local ~]# /sbin/chkconfig --add mysql 
[root@local ~]# cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@local ~]# chmod +x /etc/init.d/mysql
[root@local ~]# /sbin/chkconfig --add mysql

3.启动mysql服务

能够加入系统变量:export PATH=/usr/local/mysql/bin/:$PATH
[plain] view plaincopyprint?01.[root@local ~]# service mysql start 

假设出现错误Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/iZ23i33p2ccZ.pid).等

则可查看日志cat /usr/local/mysql/data/iZ23i33p2ccZ.err

运行/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data自己主动刷新重新启动下

我的解决方法是：

可能是/usr/local/mysql/data/rekfan.pid文件没有写的权限
解决方法 ：给予权限，运行 “chown -R mysql:mysql /var/data” “chmod -R 755 /usr/local/mysql/data”  然后又一次启动mysqld！

測试mysql是否成功安装

[plain] view plaincopyprint?01.[root@local ~]# /usr/local/mysql/bin/mysql -u root -p 
02.Enter password:  
03.Welcome to the MySQL monitor.  Commands end with ; or g.

24.4 rows in set (0.03 sec)

假设遇到错误 

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

我的解决方法：

创建符号连接：

为mysql.sock添加软连接（相当于windows中的快捷方式）。

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

參考网址： http://blog.csdn.net/wyzxg/article/details/4720041

2015-1-24加入例如以下内容，安装完毕后

改动MySQL的root用户的password以及打开远程连接

[root@localhost mysql]# mysql -u root mysql

mysql> use mysql;
mysql> desc user;
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root"; //为root加入远程连接的能力
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

假设不行则能够尝试
