메모: gitlab - ce 교체 (2)

필기 2gitlab 의 9.4.3 버 전 을 예 로 들 면 [toc]
1. nginx / apache 교체 gitlab - nginx

수정 /etc/gitlab/gitlab.rb:

nginx['enable'] = false

##     ，
## nginx：nginx.conf     user（    www www）
## apache：httpd.conf     User Group （    daemon daemon）
web_server['external_users'] = ['www']


##    apache，      ,nginx  
gitlab_workhorse['listen_network'] = "tcp"
gitlab_workhorse['listen_addr'] = "127.0.0.1:8181"

# gitlab-workhorse is listening on port 8181. To allow gitlab-workhorse to
# listen on port 8181, edit /etc/gitlab/gitlab.rb and change the following:
#
# gitlab_workhorse['listen_network'] = "tcp"
# gitlab_workhorse['listen_addr'] = "127.0.0.1:8181"

2, mysql 교체 gitlab - postgres ：gitlab-ce-9.4.3-ce.0.el7.x86_64.rpm ，，。 ： gitlab mysql ，。（，）
(1) gitlab 에 권한 계 정 을 설정 하고 라 이브 러 리 를 만 듭 니 다.

mysql> grant all privileges on *.* to gitlab@"localhost" identified by "lzour";
mysql> flush privileges;
mysql> CREATE DATABASE IF NOT EXISTS `gitlab` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_general_ci`;

(2) gitlab 설정 수정 /etc/gitlab/gitlab.rb:

#    postgresql
postgresql['enable'] = false

# mysql   
gitlab_rails['db_adapter'] = 'mysql2'
gitlab_rails['db_encoding'] = 'utf8'
#       ，    IP  
gitlab_rails['db_host'] = '127.0.0.1'
gitlab_rails['db_port'] = '3306'
gitlab_rails['db_username'] = 'gitlab'
gitlab_rails['db_password'] = 'lzour'
gitlab_rails['db_host'] = "127.0.0.1"
gitlab_rails['db_port'] = 3306

(3) 설정 후 실행 gitlab-ctl reconfigure, 오류 발생

[root@stone ~]# gitlab-ctl reconfigure
