5 # you can set CFLAGS before running installer
17 ${ME} <installer options>
19 Valid <installer options> are:
21 --install /PATH/TO/INSTALL
23 If your give: --install /opt
24 netdata will be installed in /opt/netdata
28 Do not (re)start netdata.
33 Do not wait for the user to press ENTER.
34 Start immediately building it.
38 If you get errors about missing zlib,
39 but you know it is available,
40 you have a broken pkg-config.
41 Use this option to allow it continue
42 without checking pkg-config.
44 Netdata will by default be compiled with gcc optimization -O3
45 If you need to pass different CFLAGS, use something like this:
47 CFLAGS="<gcc options>" $ME <installer options>
49 For the installer to complete successfully, you will need
50 these packages installed:
52 gcc make autoconf automake pkg-config zlib1g-dev
54 For the plugins, you will at least need:
63 if [ "$1" = "--install" ]
65 NETDATA_PREFIX="${2}/netdata"
67 elif [ "$1" = "--zlib-is-really-here" ]
71 elif [ "$1" = "--dont-start-it" ]
75 elif [ "$1" = "--dont-wait" ]
79 elif [ "$1" = "--help" -o "$1" = "-h" ]
86 echo >&2 "I cannot understand option '$1'."
95 Nice to see you are giving it a try!
97 You are about to build and install netdata to your system.
99 It will be installed at these locations:
101 - the daemon at ${NETDATA_PREFIX}/usr/sbin/netdata
102 - config files at ${NETDATA_PREFIX}/etc/netdata
103 - web files at ${NETDATA_PREFIX}/usr/share/netdata
104 - plugins at ${NETDATA_PREFIX}/usr/libexec/netdata
105 - cache files at ${NETDATA_PREFIX}/var/cache/netdata
106 - log files at ${NETDATA_PREFIX}/var/log/netdata
108 This installer allows you to change the installation path.
109 Press Control-C and run the same command with --help for help.
113 if [ ! "${UID}" = 0 -o "$1" = "-h" -o "$1" = "--help" ]
116 echo >&2 "You have to run netdata as root."
117 echo >&2 "The netdata daemon will drop priviliges"
118 echo >&2 "but you have to start it as root."
123 if [ ${DONOTWAIT} -eq 0 ]
125 if [ ! -z "${NETDATA_PREFIX}" ]
127 read -p "Press ENTER to build and install netdata to '${NETDATA_PREFIX}' > "

141 Sorry! NetData failed to build...
143 You many need to check these:
145 1. The package zlib1g-dev has to be installed.
147 2. You need basic build tools installed, like:
149 gcc make autoconf automake pkg-config
151 3. If your system cannot find ZLIB, although it is installed
152 run me with the option: --zlib-is-really-here
154 If you still cannot get it to build, ask for help at github:
