一行入魂

Ubuntuに最新のjemallocをインストールしたいのですが
なぜかppaにあるのはバージョン3系ばかりで最新の4系が無いんですよ。
なので、Ansibleでソースからインストールするroleを書いてみました。

tasks/main.yaml

- name: "test jemalloc"
  command: bash -lc "ls -la {{ src_dir }}|grep {{ jemalloc_name }}"
  register: jemalloc_installed
  ignore_errors: yes

- name: "get file"
  get_url:
    url: "{{ jemalloc_url }}"
    dest: "{{ src_dir }}"
    mode: 0664
  when: jemalloc_installed|failed

- name: "unarchive"
  unarchive:
    copy: no
    src: "{{ jemalloc_archive }}"
    dest: "{{ src_dir }}"
  when: jemalloc_installed|failed

- name: "rm archive"
  file:
    path: "{{ jemalloc_archive }}"
    state: absent
  when: jemalloc_installed|failed

- name: "configure"
  command: ./configure
  args:
    chdir: "{{ jemalloc_dir }}"
  when: jemalloc_installed|failed

- name: "make"
  command: make
  args:
    chdir: "{{ jemalloc_dir }}"
  when: jemalloc_installed|failed

- name: "setting"
  template:
    src: ld.so.preload.j2
    dest: /etc/ld.so.preload
    mode: 0644
    owner: root
    group: root
  when: jemalloc_installed|failed
  become: yes

templates/ld.so.preload.j2

{{ jemalloc_library }}

vars/main.yaml

jemalloc_version: "4.0.4"
jemalloc_name: "jemalloc-{{ jemalloc_version }}"
jemalloc_url: "https://github.com/jemalloc/jemalloc/releases/download/{{ jemalloc_version }}/{{ jemalloc_name }}.tar.bz2"
jemalloc_dir: "{{ src_dir }}/{{ jemalloc_name }}"
jemalloc_archive: "{{ jemalloc_dir }}.tar.bz2"
jemalloc_library: "{{ jemalloc_dir }}/lib/libjemalloc.so"
