10 Database backup |
|
11 ^^^^^^^^^^^^^^^ |
|
12 It is always wise to back up your database from time to time. |
|
13 Particularly with regard to an impending structure modification. |
|
14 |
|
15 Example: Backing up the `mailsys` database with pg_dump_. |
|
16 |
|
17 .. code-block:: console |
|
18 |
|
19 root@host:~# pg_dump -h localhost -U vmm -W mailsys > mailsys-0.4.sql |
|
20 |
|
21 Stopping Postfix and Dovecot |
|
22 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
23 Before updating the database you have to stop Postfix and Dovecot. |
|
24 |
|
25 .. code-block:: console |
|
26 |
|
27 root@host:~# /etc/init.d/postfix stop |
|
28 Stopping Postfix Mail Transport Agent: postfix. |
|
29 root@host:~# /etc/init.d/dovecot stop |
|
30 Stopping IMAP/POP3 mail server: dovecot. |
|
31 |
|
32 Database update |
|
33 ^^^^^^^^^^^^^^^ |
|
34 Connect as your `vmm` database user to your database. |
|
35 |
|
36 .. code-block:: console |
|
37 |
|
38 root@host:~# psql mailsys vmm -W -h localhost |
|
39 |
|
40 In the PostgreSQL interactive terminal you have to run the following |
|
41 commands to perform the update. |
|
42 |
|
43 .. code-block:: postgresql-console |
|
44 |
|
45 mailsys=> \i /path/to/vmm-0.5.2/update_tables_0.4.x-0.5.pgsql |
|
46 mailsys=> GRANT SELECT ON postfix_alias TO postfix; |
|
47 mailsys=> \q |
|
48 |
|
49 .. _database-update-for-dovecot-v1-2-x: |
|
50 |
|
51 Database update for Dovecot v1.2.x |
|
52 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
53 When you are already using Dovecot v1.2.x, you have to perform one or two |
|
54 **additional** database updates. |
|
55 |
|
56 .. code-block:: postgresql-console |
|
57 |
|
58 mailsys=> \i /path/to/vmm-0.5.2/update_tables_0.5.x_for_dovecot-1.2.x.pgsql |
|
59 mailsys=> GRANT SELECT ON dovecot_password TO dovecot; |
|
60 mailsys=> -- If you are using the function dovecotpassword() in the |
|
61 mailsys=> -- password_query setting of your dovecot-sql.conf update it also: |
|
62 mailsys=> \i /path/to/vmm-0.5.2/update_types_and_functions_0.5.x_for_dovecot-1.2.x.pgsql |
|
63 mailsys=> \q |
|

|
65 .. _adjusting-permissions-of-the-setuid-root-deliver-copy: |
|
66 |
|
67 Adjusting permissions of the setuid root deliver copy |
|
68 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
69 Starting with Dovecot version 1.2.0 the LDA ``deliver`` will no longer |
|
70 work, if the binary has the setuid-root bit set **and** it's executable |
|
71 for everyone. |
|
72 Independent of the directory permissions, where the ``deliver`` binary |
|
73 is located. |
|
74 For this reason you have to adjust the permission of the ``deliver`` binary. |
|
75 |
|
76 .. code-block:: console |
|
77 |
|
78 root@host:~# chown root:`id -g nobody` /usr/local/lib/dovecot/deliver |
|
79 root@host:~# chmod u+s,o-rwx /usr/local/lib/dovecot/deliver |
|
80 |
|
81 .. _check-update-postfix-master-cf: |
|
82 |
|
83 Check/update Postfix' master.cf |
|
84 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
85 In prior setups the service *dovecot* was configured slightly different. |
|
86 If you have set the command attribute user to ``nobody:mail``, either |
|
87 remove the group *mail* or replace it with the group *nobody* or *nogroup*. |
|
88 The second line of the service *dovecot* entry should look similar to this:: |
|
89 |
|
90 flags=DORhu user=nobody argv=/usr/local/lib/dovecot/deliver … |
|
91 |
|
92 Start Dovecot and Postfix again |
|
93 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
|
94 After a successfully update start Dovecot and Postfix again. |
|
95 |
|
96 .. code-block:: console |
|
97 |
|
98 root@host:~# /etc/init.d/dovecot start |
|
99 Starting IMAP/POP3 mail server: dovecot. |
|
100 root@host:~# /etc/init.d/postfix start |
|
101 Starting Postfix Mail Transport Agent: postfix. |
|
102 |
|
103 Upgrade vmm |
|
104 ^^^^^^^^^^^ |
|
105 Finally execute the ``upgrade.sh`` script to install the new code and |
|
106 update your ``/usr/local/etc/vmm.cfg``. |
|
107 |
|
108 .. code-block:: console |
|
109 |
|
110 root@host:~# cd /path/to/vmm-0.5.2 |
|
111 root@host:/path/to/vmm-0.5.2# ./upgrade.sh |
|
112 |
|
113 Please have a look at your /usr/local/etc/vmm.cfg |
|
114 and verify the value from option 'postconf' in section 'bin'. |
|
115 |
|
116 root@host:/path/to/vmm-0.5.2# |
|
117 |
|
118 Upgrading from vmm-0.5.x |
|
119 ------------------------ |
|
120 Upgrade vmm |
|
121 ^^^^^^^^^^^ |
|
122 When you have already installed vmm-0.5 or vmm-0.5.1 only a single step is |
|
123 necessary to update your vmm installation. |
|
124 cd in the source directory and execute the ``upgrade.sh`` script. |
|
125 That's it. |
|
126 |
|
127 .. code-block:: console |
|
128 |
|
129 root@host:~# cd /path/to/vmm-0.5.2 |
|
130 root@host:/path/to/vmm-0.5.2# ./upgrade.sh |
|
131 root@host:/path/to/vmm-0.5.2# |
|
132 |
