GitLab在Centos下的安装步骤

第一步:(安装工具包)

sudo yum install curl openssh-server postfix cronie
sudo service postfix start
sudo chkconfig postfix on
sudo lokkit -s http -s ssh

第二步:（安装ruby，如果已安装则可跳过这个步骤）

sudo yum install ruby ruby-irb

第三步：（下载并安装gitlab-ce-xx.rpm安装包）

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install gitlab-ce

如果下载过于缓慢或下载失败，则可选择使用以下方式

http://pan.baidu.com/s/1kTzsCfX

如果已成功下载，则使用下面的命令安装

rpm -i gitlab-ce-XXX.rpm

第四步：(修复软连接)

首先修复modprobe

rm -f /sbin/modprobe
ln -s /bin/true /sbin/modprobe

其次修复sysctl

rm -f /sbin/sysctl
ln -s /bin/true /sbin/sysctl

如果在配置使用过程中，出现了以下错误，一定要使用上述操作步骤进行修复

error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key
error: permission denied on key 'net.ipv4.tcp_max_syn_backlog'
error: permission denied on key 'net.core.netdev_max_backlog'
error: permission denied on key 'net.core.wmem_default'
error: permission denied on key 'net.core.rmem_default'
error: permission denied on key 'net.core.rmem_max'
error: permission denied on key 'net.core.wmem_max'
error: permission denied on key 'net.ipv4.tcp_timestamps'
error: permission denied on key 'net.ipv4.tcp_synack_retries'
error: permission denied on key 'net.ipv4.tcp_syn_retries'
error: permission denied on key 'net.ipv4.tcp_tw_recycle'
error: permission denied on key 'net.ipv4.tcp_tw_reuse'
error: permission denied on key 'net.ipv4.tcp_mem'
error: permission denied on key 'net.ipv4.tcp_max_orphans'
error: permission denied on key 'net.ipv4.ip_local_port_range'

第五步：（修改日志文件夹的访问权限）

sudo chmod -R  /var/log/gitlab

第六步：（配置gitlab.rb文件，主要看未注释掉的代码部分）

sudo nano /etc/gitlab/gitlab.rb

修改后的文件如下

## Latest options listed at https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-config-template/gitlab.rb.template

## Url on which GitLab will be reachable.

注：在这里唯一需要修改的就是把文件里xxxxxxxx@163.com这个邮件地址改为自己真实可用的邮箱地址即可，好像一共有三处；其次别忘了在这里修改自己的邮箱密码，如果是163邮箱，录入的密码不是真实的邮箱密码，而是代理密码，即一个加密后的密码串，具体情况自己可登录163邮箱查看。

gitlab_rails['smtp_user_name'] = "xxxxxxxx@163.com"
gitlab_rails['smtp_password'] = "mjaiuhvi"

第七步：（修改PostgreSQL的配置文件）

在这里需要依次修改两个文件（如果你需要远程访问PostgreSQL数据库，需要再额外的修改postgresql.conf文件），分别为pg_hba.conf与postgresql.conf文件

sudo nano /var/opt/gitlab/postgresql/data/pg_hba.conf
sudo nano /var/opt/gitlab/postgresql/data/postgresql.conf

1）配置待访问的主机IP（客户端）

# This file is managed by gitlab-ctl. Manual changes will be
# erased! To change the contents below, edit /etc/gitlab/gitlab.rb
# and run `sudo gitlab-ctl reconfigure`.

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the
# PostgreSQL documentation for a complete description
# of this file.  A short synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access.  Records take one of these forms:
#
# local      DATABASE  USER  METHOD  [OPTION]
# host       DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostssl    DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostnossl  DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain socket,
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", a database name, or
# a comma-separated list thereof.
#
# USER can be "all", a user name, a group name prefixed with "+", or
# a comma-separated list thereof.  In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names from
# a separate file.
#
# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between  and  (IPv4) or  (IPv6) inclusive) that specifies
# the number of significant bits in the mask.  Alternatively, you can write
# an IP address and netmask in separate columns to specify the set of hosts.
#
# METHOD can be "trust", "reject", "md5", "crypt", "password", "gss", "sspi",
# "krb5", "ident", "pam" or "ldap".  Note that "password" sends passwords
# in clear text; "md5" is preferred since it sends encrypted passwords.
#
# OPTION is the ident map or the name of the PAM service, depending on METHOD.
#
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
# "samerole" makes the name lose its special character, and just match a
# database or username with that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal.  If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect.  You can use
# "pg_ctl reload" to do that.

# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL listen
# on a non-local interface via the listen_addresses configuration parameter,
# or via the -i or -h command line switches.
#

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               trust
host    all            all            192.168.30.0/          trust
host    all            all            192.168.10.0/          trust
#map=gitlab

如果希望某个IP段的主机也可以访问数据库，只需再增加这个段就可以了，例如192.168.10.0~192.168.10.255，就可以写成以下的方式

host    all            all            192.168.10.0/          trust

2）启用监听所有客户端

 # This file is managed by gitlab-ctl. Manual changes will be
 # erased! To change the contents below, edit /etc/gitlab/gitlab.rb
 # and run `sudo gitlab-ctl reconfigure`.

 # -----------------------------
 # PostgreSQL configuration file
 # -----------------------------
 #
 # This file consists of lines of the form:
 #
 #   name = value
 #
 # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
 # "#" anywhere on a line.  The complete list of parameter names and allowed
 # values can be found in the PostgreSQL documentation.
 #
 # The commented-out settings shown in this file represent the default values.
 # Re-commenting a setting is NOT sufficient to revert it to the default value;
 # you need to reload the server.
 #
 # This file is read on server startup and when the server receives a SIGHUP
 # signal.  If you edit the file on a running system, you have to SIGHUP the
 # server for the changes to take effect, or use "pg_ctl reload".  Some
 # parameters, which are marked below, require a server shutdown and restart to
 # take effect.
 #
 # Any parameter can also be given as a command-line option to the server, e.g.,
 # "postgres -c log_connections=on".  Some parameters can be changed at run time
 # with the "SET" SQL command.
 #
 # Memory units:  kB = kilobytes        Time units:  ms  = milliseconds
 #                MB = megabytes                     s   = seconds
