Configure, compile and install AOLserver. Many people need to run more than one version of AOLserver in parallel. This section accomodates future upgrades by installing AOLserver 4 in /usr/local/aolserver40r2.

[root aolserver]# cd /usr/local/src/aolserver40r2/aolserver
[root aolserver]# ./configure --prefix=/usr/local/aolserver40r2 --with-tcl=/usr/local/lib/
[root aolserver]# make install
      cd /usr/local/src/aolserver40r2/aolserver
./configure --prefix=/usr/local/aolserver40r2 --with-tcl=/usr/local/lib/
make install
ln -s /usr/local/aolserver40r2 /usr/local/aolserver

If this is the only version of AOLserver in use, or is the default version, create a symlink. If not, then be sure to use /usr/local/aolserver40r2 instead of /usr/local/aolserver in future steps.

[root aolserver]# ln -s /usr/local/aolserver40r2 /usr/local/aolserver

Configure, compile and install the modules.
1. Install nscache
```
[root aolserver]# cd /usr/local/src/aolserver40r2/nscache
[root nscache]# make install
```
2. Install nsoracle (if you want to use Oracle)
```
[root nscache]# cd ../nsoracle
[root nsoracle]# make install
```
3. Install nspostgres (if you want to use Postgres)
```
[root nsrewrite]# cd ../nspostgres
[root nspostgres]# make install POSTGRES=LSB ACS=1 INST=/usr/local/aolserver40r2 
```
  If you get errors like:
```
nspostgres.c: In function `Ns_PgTableList':
nspostgres.c:679: warning: passing arg 3 of `Tcl_DStringAppend' as signed due to prototype
```
  then PostGreSQL is probably not in the standard location. The location of PostGreSQL is very dependent on which method was used to install it. To correct the problem, replace LSB with the path to the path to your PostGreSQL installation. Often this is /usr/local/pgsql.
  Another possibility is that you may need to set the LD_LIBRARY_PATH environmental variable. You may still get warnings, but sometimes this will fix things enough to work.
```
[root nspostgres]# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib
              
```
  You can use the ldd command to verify that all libraries are linked in: ldd nspostgres.so
  If you run into problems with libpq.a do the following (and repeat the step above)
```
[root nspostgres]# ranlib /usr/local/pgsql/lib/libpq.a
```
  If you run into problems with the linker, edit the Makefile. Add -lnsdb to the MODLIBS var.
```
MODLIBS = -L$(PGLIB) -lpq -lnsdb
```
4. Install nssha1
```
[root nsrewrite]# cd ../nssha1
[root nssha1]# make
```
  If the make fails you will have to edit nssha1.c. Comment out the following 2 lines (lines 139-140):
```
// typedef unsigned int u_int32_t;
// typedef unsigned char u_int8_t;
```
  Now install nssha1:
```
[root nssha1]# make install
```
5. Install tDOM
```
[root nssha1]# cd ../tDOM-0.7.8/unix
```
  Edit the CONFIG file. Uncomment the instructions meant for AOLserver 4, but edit it to look like this:
```
../configure --enable-threads --disable-tdomalloc
          --prefix=/usr/local/aolserver40r2 --with-tcl=/usr/local/lib
```
  Now you can compile and configure tDOM
```
[root unix]# sh CONFIG
[root unix]# make install
```

Add a database-specific wrapper script. This script sets database environment variables before starting AOLserver; this allows the AOLserver instance can communicate with the database. There is one script each for Oracle and PostgreSQL. They don't conflict, so if you plan to use both databases, install both.

Oracle

[root aolserver]# cd /usr/local/aolserver40r2/bin
[root bin]# cp /tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/nsd-oracle.txt ./nsd-oracle
[root bin]# chmod 750 nsd-oracle
[root bin]#
cd /usr/local/aolserver40r2/bin
cp /tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/nsd-oracle.txt ./nsd-oracle
chmod 750 nsd-oracle

PostgreSQL

[root aolserver]# cd /usr/local/aolserver40r2/bin
[root bin]# cp /tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/nsd-postgres.txt ./nsd-postgres
[root bin]# chmod 755 nsd-postgres
[root bin]#
cd /usr/local/aolserver40r2/bin
cp /tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/nsd-postgres.txt ./nsd-postgres
chmod 755 nsd-postgres

You may need to edit these scripts if you are not using /usr/local/aolserver as the directory of Aolserver4.

Change startup script (optional). If you want to run AOLserver on a port below 1024 (normally, for a webserver you will use 80), you will have to change the /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/daemontools/run script according to the documentation found there (namely: Add the -b yourip:yourport switch)
Test AOLserver.
