The MySQL herd is proud to announce that MySQL 4.1 can now be found in Gentoo's |
| 79 |
unstable tree (~arch). As the team hopes that it soon will be able to stabilize |
| 80 |
this ebuild, here's an upgrade path for all willing testers. |

<p> |
| 96 |
Users upgrading from an old version (<4.0.24) of MySQL will first have to |
| 97 |
install MySQL 4.0.25. If you are already running a current version, you can skip |
| 98 |
this section and continue with the next one. |
| 99 |
</p> |
| 100 |
|
| 101 |
<pre caption="Simple upgrade"> |
| 102 |
# <i>emerge -av --buildpkg "<mysql-4.1"</i> |
| 103 |

<title>Creating a backup of your current data</title> |

<section> |

|
| 114 |
<p> |
| 115 |
One of the fundamental works of every database administrator is ... to make |
| 116 |
backup of the data. So proceed with one. |
| 117 |
</p> |
| 118 |
|
| 119 |
<pre caption="Dump of all databases"> |
| 120 |
# <i>mysqldump \</i> |
| 121 |
<i>-uroot \</i> |
| 122 |
<i>-p$PASSWORD \</i> |
| 123 |
<i>-hlocalhost \</i> |
| 124 |
<i>--all-databases \</i> |
| 125 |
<i>--all \</i> |
| 126 |
<i>--opt \</i> |
| 127 |
<i>--allow-keywords \</i> |
| 128 |
<i>--flush-logs \</i> |
| 129 |
<i>--hex-blob \</i> |
| 130 |
<i>--master-data \</i> |
| 131 |
<i>--max_allowed_packet=16M \</i> |
| 132 |
<i>--result-file=BACKUP_MYSQL_4.0.SQL</i> |
| 133 |
</pre> |
| 134 |
|
| 135 |
<p> |
| 136 |
Now a file named <path>BACKUP_MYSQL_4.0.SQL</path> should exist, this one can be |
| 137 |
used to recreate your data, the data is described in the MySQL dialect of SQL, |
| 138 |
the Structured Query Language. |
| 139 |
</p> |
| 140 |
|
| 141 |
<p> |
| 142 |
This would be a good time to see if the backup you have created is working. |
| 143 |
</p> |
| 144 |
|
| 145 |
</body> |
| 146 |
</section> |

<chapter> |

<title>Upgrading from recent versions of MySQL</title> |
| 151 |
<section> |
| 152 |
<body> |
| 153 |
|
| 154 |
<p> |
| 155 |
If you have skipped step #1, you now have to create a backup package (the |
| 156 |
database server, not the data) of the currently installed version: |
| 157 |
</p> |
| 158 |
|
| 159 |
<pre caption="Binary package backup"> |
| 160 |
# <i>quickpkg dev-db/mysql</i> |
| 161 |
</pre> |
| 162 |
|
| 163 |
<p> |
| 164 |
Now it's time to clean out the current version and all it's data: |
| 165 |
</p> |
| 166 |
|
| 167 |
<pre caption="Uninstall MySQL"> |
| 168 |
# <i>/etc/init.d/mysql stop</i> |
| 169 |
# <i>emerge -C mysql</i> |
| 170 |
# <i>tar -cjpvf ~/mysql.$(date +%F_%H-%M).tar.bz2 /etc/mysql/my.cnf /var/lib/mysql/</i> |
| 171 |
# <i>ls -l ~/mysql.*</i> |
| 172 |
# <i>rm -rf /var/lib/mysql/ /var/log/mysql</i> |
| 173 |
</pre> |
| 174 |
|
| 175 |
<note> |
| 176 |
At this time two backup should exist, one portable between various MySQL |
| 177 |
versions, the SQL one. <br /> |
| 178 |
The other instead permit to restore quickly the system at this point. Later on |
| 179 |
this doc will be explain how to recover from this last one. |
| 180 |
</note> |
| 181 |
|
| 182 |
<p> |
| 183 |
After you got rid of your old MySQL installation, you can now install the new |
| 184 |
version. Note that <c>revdep-rebuild</c> is necessary for rebuilding packages |
| 185 |
linking against MySQL. |
| 186 |
</p> |
| 187 |
|
| 188 |
<pre caption="Upgrading the binaries"> |
| 189 |
# <i>emerge -av ">mysql-4.1"</i> |
| 190 |
# <i>dispatch-conf</i> |
| 191 |
# <i>revdep-rebuild</i> |
| 192 |
</pre> |
| 193 |
|
| 194 |
<p> |
| 195 |
Now configure the newly installed version of MySQL and restart the daemon: |
| 196 |
</p> |
| 197 |
|
| 198 |
<pre caption="Configure MySQL 4.1 base setup"> |
| 199 |
# <i>ebuild /var/db/pkg/dev-db/mysql-4.1.<micro_version>/mysql-4.1.<micro_version>.ebuild config</i> |
| 200 |
# <i>/etc/init.d/mysql start</i> |
| 201 |
</pre> |
| 202 |
|
| 203 |
<p> |
| 204 |
Finally you can import the backup you have created during step #2: |
| 205 |
</p> |
| 206 |
|
| 207 |
<pre caption="Importing the SQL backup"> |
| 208 |
# <i>cat BACKUP_MYSQL_4.0.SQL \</i> |
| 209 |
<i>| mysql \</i> |
| 210 |
<i>-uroot \</i> |
| 211 |
<i>-p$PASSWORD \</i> |
| 212 |
<i>-hlocalhost \</i> |
| 213 |
<i>--max_allowed_packet=16M</i> |
| 214 |
|
| 215 |
# <i>mysql_fix_privilege_tables \</i> |
| 216 |
<i>--defaults-file=/etc/mysql/my.cnf \</i> |
| 217 |
<i>--user=root \</i> |
| 218 |
<i>--password=$PASSWORD</i> |
| 219 |
</pre> |
| 220 |
|
| 221 |
<p> |
| 222 |
If you now restart your MySQL daemon and everything went as expected, you will |
| 223 |
have a fully working version of 4.1.x! :-) |
| 224 |
</p> |
| 225 |
|
| 226 |
<pre caption="Restart the MySQL instance"> |
| 227 |
# <i>/etc/init.d/mysql restart</i> |
| 228 |
</pre> |
| 229 |
|
| 230 |
<p> |
| 231 |
If you encountered any problems during the upgrade process, please report them |
| 232 |

If the result is not fully satisfactory, it's possible to reinstall the old |
| 246 |
MySQL 4.0 version. |
