postmaster.pid權限被拒絕的CentOS 7

Question

的Postgres 9.2在CentOS 7

後 「蘇 - Postgres的」 我用

PG-CTL在initdb -D在/ var/lib中/ pgsql的/數據

裝

運行良好。

當我 「蘇 - Postgres的」 我能 「碰」 的文件， 「LS」 的文件， 「RM」 /var/lib/pgsql/data/postmaster.pid。數據權限爲700個postgres：postgres。 pgsql是/ data0/postgres的一個符號鏈接，postgres是700個postgres：postgres。

ADDITIONS：

我忘了提及，有這個問題後，我取代爲ExecStartPre和ExecStart的命令與寫的用戶，主組，PGDATA和PGPORT值到一個文件殼腳本。他們都是正確的。開始仍然在postmaster.pid上死亡。

的postgresql.service文件：

[root@server /]# cat /usr/lib/systemd/system/postgresql.service 
# It's not recommended to modify this file in-place, because it will be 
# overwritten during package upgrades. If you want to customize, the 
# best way is to create a file "/etc/systemd/system/postgresql.service", 
# containing 
#  .include /lib/systemd/system/postgresql.service 
#  ...make your changes here... 
# For more info about custom unit files, see 
# http://fedoraproject.org/wiki/Systemd#How_do_I_customize_a_unit_file.2F_add_a_custom_unit_file.3F 

# For example, if you want to change the server's port number to 5433, 
# create a file named "/etc/systemd/system/postgresql.service" containing: 
#  .include /lib/systemd/system/postgresql.service 
#  [Service] 
#  Environment=PGPORT=5433 
# This will override the setting appearing below. 

# Note: changing PGPORT or PGDATA will typically require adjusting SELinux 
# configuration as well; see /usr/share/doc/postgresql-*/README.rpm-dist. 

# Note: do not use a PGDATA pathname containing spaces, or you will 
# break postgresql-setup. 

# Note: in F-17 and beyond, /usr/lib/... is recommended in the .include line 
# though /lib/... will still work.

Answer 1

我想通了。運行initdb後，我將數據目錄複製到另一個驅動器。通過SELinux，FILETYPE切換到目標父目錄FILETYPE。我試圖semanage的目錄，但這是行不通的。所以我重新開始並移動了數據目錄，而保留了FILETYPE。
