OpenSolaris0811中使用tar.gz成功安装配置mysql

使用mysql安装文件mysql-5.0.67-solaris10-i386.tar.gz成功在OpenSolaris0811上安装

解压文件
dong@opensolaris:~/Download$ gtar xvf mysql-5.0.67-solaris10-i386.tar.gz

生成目录
dong@opensolaris:~/Download$ ls -l | grep mysql
drwxr-xr-x 14 dong staff 19 2008-08-04 21:40 mysql-5.0.67-solaris10-i386
-rwxr-xr-x 1 dong staff 56209790 2009-05-07 21:54 mysql-5.0.67-solaris10-i386.tar.gz

移动目录，我将mysql安装在/opt下
dong@opensolaris:~/Download$ pfexec mv mysql-5.0.67-solaris10-i386 /opt/mysql
dong@opensolaris:~/Download$ cd /opt/mysql

切换到root，懒得老是打pfexec
dong@opensolaris:/opt/mysql$ su
Password:
dong@opensolaris:/opt/mysql#

添加mysql用户组和用户，不过OpenSolaris0811貌似默认就有了，安全起见在跑一次
dong@opensolaris:/opt/mysql# groupadd mysql
UX: groupadd: ERROR: mysql is already in use. Choose another.
dong@opensolaris:/opt/mysql# useradd -g mysql mysql
UX: useradd: ERROR: mysql is already in use. Choose another.

转换mysql目录的所有权
dong@opensolaris:/opt/mysql# chown -R mysql .
dong@opensolaris:/opt/mysql# chgrp -R mysql .

运行mysql数据库安装脚本
dong@opensolaris:/opt/mysql# ./scripts/mysql_install_db --user=mysql

启动mysql数据库服务
dong@opensolaris:/opt/mysql# ./bin/mysqld_safe --user=mysql &

关闭mysql数据库服务
dong@opensolaris:/opt/mysql# ./bin/mysqladmin -u root shutdown

到此mysql安装完成，不过仍然存在不少问题

问题一：找不到mysql数据目录，因为mysql的默认安装目录是/usr/local/mysql

dong@opensolaris:/opt/mysql$ ./bin/mysqld_safe --user=mysql &
[1] 919
nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /usr/local/mysql/data
./bin/mysqld_safe[380]: /usr/local/mysql/data/opensolaris.err: cannot create [No such file or directory]
./bin/mysqld_safe[388]: eval[1]: /usr/local/mysql/data/opensolaris.err: cannot create [No such file or directory]
STOPPING server from pid file /usr/local/mysql/data/opensolaris.pid
tee: /usr/local/mysql/data/opensolaris.err: No such file or directory
090513 23:17:14 mysqld ended
tee: /usr/local/mysql/data/opensolaris.err: No such file or directory

[1]+ Exit 1 ./bin/mysqld_safe --user=mysql

解决方法：使用mysql的配置文件
support-files目录下自带了一些配置文件，我使用的是my-small.cnf，将它copy到/etc下，并重命名为my.cnf，配置一下mysqld_safe

dong@opensolaris:/opt/mysql/support-files# cp my-small.cnf /etc/my.cnf
在文件中增加mysqld_safe的配置
[mysqld_safe]
basedir=/opt/mysql
datadir=/opt/mysql/data

问题二：权限问题，除了root或者用pfexec外，其他用户不能启动服务

dong@opensolaris:/opt/mysql$ ./bin/mysqld_safe --user=mysql &
[1] 1081
nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /opt/mysql/data
./bin/mysqld_safe[380]: /opt/mysql/data/opensolaris.err: cannot create [Permission denied]
rm: cannot remove `/opt/mysql/data/opensolaris.pid': Permission denied
./bin/mysqld_safe[388]: eval[1]: /opt/mysql/data/opensolaris.err: cannot create [Permission denied]
STOPPING server from pid file /opt/mysql/data/opensolaris.pid
tee: /opt/mysql/data/opensolaris.err: Permission denied
090513 23:34:01 mysqld ended
tee: /opt/mysql/data/opensolaris.err: Permission denied

发生这问题主要是因为data权限的问题，以下是我更改之前的权限
drwxr-x--- 4 mysql mysql 8 2009-05-13 23:15 data

我的做法是更改目录权限，并为经常使用的用户添加mysql附属组
dong@opensolaris:/opt/mysql# chmod 770 data
dong@opensolaris:/opt/mysql# usermod -G "mysql" dong
UX: usermod: dong is currently logged in, some changes may not take effect until next login.
重新登录，并查看一下自己的信息
dong@opensolaris:~$ id -a
uid=101(dong) gid=10(staff) groups=10(staff),70(mysql)
dong@opensolaris:~$ cd /opt/mysql/
dong@opensolaris:/opt/mysql$ ./bin/mysqld_safe --user=mysql &
[1] 1215
nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /opt/mysql/data

dong@opensolaris:/opt/mysql$ ps -ef | grep mysql
dong 1215 1198 0 23:44:00 pts/2 0:00 /bin/sh ./bin/mysqld_safe --user=mysql
dong 1239 1215 0 23:44:01 pts/2 0:01 /opt/mysql/bin/mysqld --basedir=/opt/mysql --datadir=/opt/mysql/data --pid-file
dong 1245 1198 0 23:44:51 pts/2 0:00 grep mysql
正常启动，可以使用mysql工具连接测试一下
停止服务
dong@opensolaris:/opt/mysql$ ./bin/mysqladmin -u root shutdown

问题三：在其他目录下不能启动服务，必须在安装目录下才能启动

dong@opensolaris:~$ /opt/mysql/bin/mysqld_safe --user=mysql &
[1] 847
/opt/mysql/bin/mysqld_safe[199]: my_print_defaults: not found [No such file or directory]
/opt/mysql/bin/mysqld_safe[204]: my_print_defaults: not found [No such file or directory]
The file /usr/local/mysql/bin/mysqld doesn't exist or is not executable
Please do a cd to the mysql installation directory and restart
this script from there as follows:
./bin/mysqld_safe.
See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more
information

[1]+ Exit 1 /opt/mysql/bin/mysqld_safe --user=mysql

my_print_defaults在/opt/mysql/bin下的，只要将/opt/mysql/bin配置到PATH中去，就不怕找不到了
另外如果不是在安装目录下运行mysqld_safe还要指定mysqld所在的目录，这里通过配置文件解决就可以了
在[mysqld_safe]多加一条ledir=/opt/mysql/bin，用来指定mysqld所在的目录

[mysqld_safe]
basedir=/opt/mysql
datadir=/opt/mysql/data
ledir=/opt/mysql/bin

ok，启动服务

dong@opensolaris:~$ /opt/mysql/bin/mysqld_safe --user=mysql &
[1] 1328
